Amplifer Troubleshooting: What to check if your amp is cutting off, no sound, protect mode 

1:16 Finally a troubleshooting guy that actually test the voltage! I can't count how many RU-vidrs just skip the voltage like Amp regulators never fail!

I got one for ya. More frequently now, my amp will cut out. If I turn the bass up or volume up, it will come back on for a bit then cut off again. Sometimes it won't come back on at all.

JP, great video man, And if you touched on this in the video, forgive me. Cause I completely missed it LOL. My subwoofer seems to cut off once I turn the volume to a certain level. When I looked at my amp I see it is in protect mode. If I keep the volume lower. Nothing happens but as soon as I turn it up Protect mode kicks in and subwoofer cuts out. Which of the tests you showed applied to that or did you not cover that specifically? I would appreciate your help brother

Great video, troubleshooting a problem and you literally gave me the grocery list of things to test, amazing stuff

Best explanation simple and clear

hey, i'm wondering if you have experienced installing aftermarket radio with honda stream premium audio factory amplifier. i've been looking for info like where the factory amp is located and which wire from the stock harness powers the amp. so far my android unit plays normally but no sound is coming out. if i wired a speaker directly to the player, there is audio. appreciate your assistance. thanks

Thank you so much for taking time to make this 🙌

This really helped. My new amp doesn’t work. Thanks….

The crazy thing is I had subscribe before you even mentioned it I liked after seeing the quality of the video you helped a Hugh pain the neck ✊😅😂

Bro, thank you so much and love the video. I’m not sure if this vid is gonna help me solve my problem, but after watching 10+ others I can say yours is the most useful and easy for someone like me who knows nothing to have a direction to go. That being said, if I do these tests and can’t solve it, would you be down to have me send you a video of the problem and you respond diagnosing it? (The video I send will just be to you and you can use or not use it in your response, just trying to figure my problem out). Either I haven’t been searching right, or I have a unicorn but my bass just thumped with no music connected and the engine turned off with the key out the ignition 😂 anyways,gonna try all this tomorrow and weather it works or not I’ll give an update

This guys a good instructor..smooth and precise, very knowledgeable . Nice work brother

how you doing my great brother would you happen to know a good place that repairs aftermarket amps ?

The AMP power gauge accidentally touched the casing of the capacitor and caused a small spark. Does that short circuit anything and affect the SUB and AMP?

I've got a power acoustic amp I'm not sure if it's blown or not anytime it powers on both power and protect come on but then power stays on and protect leaves the chat trying to push a 3k skar 15 inch svr

My amp is instantly going into protect mode. Checked power ground, and speaker wires. Everything seems fine. So idk.. 😢

So I’ve had my system hooked up for years like 5-6. Rockford fosgate p3 12 2ohm and a 500 watt fosgate amp they actually pushes 620 watts. All of a sudden now when I turn it up it’s going into protect I never have all the settings all the way up and far as I can see all connections are good I can’t figure it out only does it on higher end of the volume

Thanks

I have a Toyota RAV4 with a JBL factory radio and it also has an amp radio come on but no sound comes out

Hey bro I have a kicker CXA 1800.1 with two Q-class L7 12's I recently upgraded my alternator and added a second power run and bigger grounds and a few fuses with a 29AH SCIB bank everything has been working fine for the past two weeks except for when I turn the car off if I open the door before everything completely shuts off it will burp my subs at Max volume for several seconds today I was checking it out clamping my setup and turned the car off and had the door open and it burped them louder than ever enough to shake the house and make the neighbors mad anyway I didn't think anything about it because it has happened several times but I went to get cigarettes about an hour ago and as soon as I turned the car on everything was fine except I was getting a major voltage drop at the positive input on the amp itself this has never happened before I literally never get voltage drop with the overkill power supply on a 2k amp so this has me really concerned I understood the amp and everything is completely fine throughout the rest of the car all the way to the lithium in the trunk right next to the amp so have I fried it it didn't have any music playing through it or anything and was dropping from 14.8 to 13.2 just driving to the gas station and it never did this before it burped today

So, I have a MTX and when I connect my positive, the ground side has sparks and is in safety mode, so you know how to fix that? I’ve changed the fuses but it’s still the same

I have a Kicker amp and I want to know about what does it mean or what do I have to do on REM what kind of wire do I use or how do I hook it up can you tell me

Hey guys. I've got 2 fosgate and P3 12s and a skar amp and DD in doors. Every once in a while. Whenever I turn up the base by the base knob or it hits hard, it doesn't go into protective mode, but it does cut out the base. the music keeps playing, but the base turns off. Wish do I do first? Could it be the amp itself and how can I know?

I have a Rockford fosgate R2-500 X1 I was Coming home from work Banging my sounds And all of a sudden My protect light comes on when the bass goes up I thought maybe it was overheated So I went home Turned it off Woke up this morning And It's doing The same thing now It won't let me Bang Keeps going into protect mode What do I need to do please help

How do I disconnect my amplifier? Can I just take the fuse out? My battery has been getting drained.

For a while now my amp has been stuck in protect mode it started one day when i had them too loud and they stopped playing and started smoking so im assuming the amp is just done 100% but i want to make sure theres no fix before i buy a new one. Right now when i put all the wiring in the amp it stays with the blue light until i put the remote wire in and then it goes back into protect mode does anybody know what the problem is or have a fix. I've alr tried letting it sit with no wiring.

Think I found the issue. Looks like I’m gonna be busy tomorrow 🤦🏻‍♂️

Nice

Bother sub is working but truck speaker does not working only sub working

Im goad 199,000k other people also struggle like me

Hello I’m in need for some help I just set up my scar 2500 watt sun and amp I get power and everything is looks wired correctly can someone help me I’m getting no sound

Hello can anyone help me I have the same issue but I don’t have an amp. I upgraded the door speakers on my car to ds18 hybrids and they are hooked up to the radio with no amp it cuts out sometimes and only the subs play how do I fix this am I forced to get a amp for the door speakers?

my amp cuts out but the power light stay on and it not go into protected mood

THESE SO CALLED TIPS IS NOT GOING TO WORK. THE REASON IS NONE OF YOU DO NOT NOTHING ON THE AMP BOARDS AND DO IN HOUSE TESTING before install it is common sense. All gronds no matter what grounding point is P.S AND THING PASS THE FRONT DASH IS ALL BAD GROUNDING POINTS PERIOD.

So a blown speaker can make the amp go into protect mode? I do have one blown speaker and when I turn it up to loud my amp light will turn red and stop working. I bought the rockville 8in sub and amp combo so I know the amp is right for these speakers also.

I have a zero gauge positive wire.. put my negative wire is a 4 gauge.. will that burn my amp out.?..now my amp no making no noises but tge light comes on ..on the amp.can somebody help me.

Thanks!

Simple for this long ass video, (solution is the ground cable.) no need to check with any volt meter. It’s obvious if you know what you’re doing. Duhhh 🤦🏻🤦🏻🤦🏻

My amp light is on blue and then goes into protect after volume goes up or the bass kicks in and then goes to red

Please answer man when I test my ac on speaker wire I’m getting nothing but when I turn my volume up real real high they turn on but it’s distorted and barley working. Everything else is good so it’s from the amp to the subs

My amp won’t get out of protect no matter what I do it was in protect when I installed it

this is such a good video. Actually showing how to diagnose instead of assuming everyone just knows what youre talking about

I will disconnect the negative but it would play bass for 2 seconds but won’t play at all with everything hooked up anyone help?

I have been the whole weekend fighting with this exact problem with my amo, low voltage in the positive and perfect on the remote cable. I did check the fuse, it does look fine me. So as soon I can today I will replace the fuse if that doesn’t fixed the I’ll run a new wire. Thank you and I let you know what happens.

Mine was working all of the sudden protection is blinking also the orange light on clip is on and power goes and goes off

Getting no sound I used a line output converter everything's working amp but the sub isn't producing any Bass

Great video .. no bullshit. Just facts. Very good at making the way things work and how to use meter understandable..

Thanks dude. Helped me out. Well made video. 💯 ............... Question tho: I have a rockford fosgate t1000x5ad..... and when I have her all hooked up, I get ZERO sign of life?? I've checked all V reading at all points with the meter. All at the correct numbers. But check it out....--->I tried taking a wire and jumping it at the B+ to Remote and when doing so.....my amp gave me a SPLIT SECOND of life with a BLUE light....then NOTHING. 🤔 **I even took it in to my local car audio shop to have them test it.....They said IT WORKS PERFECTLY!!! O_o Duh Shiiiiiit my dude?!?! lmao. ... .. . What's you're idea/opinion?? Please help me slap again!! 🙏🙏

Great video will Subscribe, J.P. did have loose ground, however still need to get the correct voltage match have levels inputs all the way down on channels 1/2 & 3/4 bridged. The 6X9 speakers are rated at 120 rms 240 max, so guessing Amp isn't 🤔 powerful enough to drive em. LET ME KNOW.

I recently changed my head unit, there was already an aftermarket radio in it I just changed to a different one, everything was just unplug and plug back in. Everything works except my amp and sub, the LED on my amp flashes red and blue and then turns off. Any ideas on what the problem is? The only wiring I had to do was cutting the remote wire off the old harness and connecting it to the new one. My amp is a Vertigo Power Acoustik 1600W

I have this amp, I used 2 different power cables, 2 ground cables, and I disconnected everything and I still have the red light, but when I disconnect the control amp, no light appears. I tried another cable and the same thing happens. Rockford fosgate r2 blinking red light with amp control

Right on time my good friend. Great video.

After my comment I realized there’s a bunch of people helping others in the comments so figure I’ll throw my issue out there. Couple weeks ago every once in a while my highs would cut out while driving ( I have a bass and a high amp). Everything except the bass would cut out. I’d pull over, shut off my truck, start it again and everything would be fine.. that started happening more often until today something stranger happened.. (While sitting in my truck waiting for it to warm up because I just replaced and filled my radiator). All of a sudden I started hearing bass. Just a thump every second or two. I checked to make sure my phone wasn’t connected to the truck (it was connected to a Bluetooth speaker in the garage) and it was still thumping. I look at my deck and it isn’t lit up at all, like it’s not powered on. I turn off my phone music, it still thumps once every second or two.. Now I have no idea what’s going on, I turn off the truck and pull the key out the ignition… still.. the thump continues.. super confused, I start the truck. The deck lights up, the Bluetooth connects to my phone and everything is fine. Now, listening to my phone through my truck, I’m watching RU-vid videos trying to figure this out.. 5-10 minutes in, my highs cut out and it’s just bass like what happened before. Anyone know the first place I should look?

Anyone knows why my amp is in protection mode then when I remove my rca cables the red light turns off. Help!

Do you have a video on how to test for ground?

My amp light is on blue but still no sound

Why does my amp read 29 volts but my battery is at 13? I've been trying to figure this out. They worked fine until the other day. All the sudden my amp is reading high and isn't in protect mode until I hook speakers to it. But I tested speakers with multimeter and they good not blown. I'm soooo lost

I have a 5000w orion amp connected 2 a 12" american bass sub. Had a pro install it worked great for around 8 months. All of a sudden now its popping and making weird noises the light keeps turning red. Once in a while it will run good then do it again

hi I have a Rockville rws 10ca 1000 amplified power car subwoofer enclosure and for some reason when i am playing music the sub will stop playing then when I play another it might turn on play for about 3 minutes then it may stop again. I thought that maybe it was the radio which was a factory radio now I have a jvc kw-560bt and I thought that fixed the problem but its doing the same thing . works when it wants to . I know that its getting power because the green light is on

This content is riveting. I read a similar book that was a linchpin in my personal growth. "A Life Unplugged: Reclaiming Reality in a Digital Age" by Theodore Blaze

Helloo , I have a BELVA-BB200ABV2 amp. My amp goes to protect mode, I don't know why. I run a wire from the (+) battery to the 12v of the amp. I connect the REM of the amp to blue wire on the radio. I get the ground from the (-) pole of the battery. Any advice is greatly appreciated.

He said, okay, we just crunk the car up😂😂😂 on Ben frank I'm tryna Crunk my shit up too😂😂

I thought my door speakers were shorting on the sheet metal but I'm not sure they're connected to the amp while running subs that should be a separate circuit

I have sony ax8100 and amplifiers was sony 4ch and sony mono block when i connects mono amp to sony ax8100 in subwoofer slot when sound was high my amp was cut off please suggest how to install

Amp is receiving power the speaker terminals aren’t reading anything on the multimeter.

I checked All the power and ground connections, I have over 12 volts I checked oms on the speaker outputs and it reads from 1 and drops to zero. Does this mean the problem lies with the sub?

7:30 what if it read .35 ohms??

im not getting anything when i check the output of my amplifier speaker wires when testing it on ac volts. what does this mean?

I have a 4 channel amp that I've had 6 yrs. This just started the FR door speaker is popping at high volume, I took it loose and connect it to the FL speaker channel 1 on the amp it stopped should I just replace the amp

Great Vid Bro Will be Checking my Protection light now keep coming on Thanks Keep up the Great Work Best Sound Instructor I watch clear and Uncut Didn't miss anythg covered it all from A to Z 💯💯💯💯

My amp & eq stopped working while I was driving. Voltage in power wire but No voltage in remote wire. Fuses aren’t blown. Connections look good. Amp & eq going to fuse box. If you could give me something I’m missing I’d appreciate the help

Question for the comments my amp got a lil warm and cut off now I don't have any bass it is not in protect mode and all my wires and fuses are good help ?

I was bumping my subs yesterday and then all of a sudden my head unit said amp error now my subs don't work. Do you know what the problem could be? Thanks

Could there be something wrong with my bass knob ? I just bought a new one it works only if it is partly plugged in the sub

Install consists of head unit ,amp ,1*12"sub and 2*6.5 mids When i switch functions on the head unit say from tuner to aux or cd ,the amplifier switches off. Only when you switch back to tuner mode on the head unit,the amp turns back on I check all the connections..

I have a problem where my subs and amp were working fine for a year, now all of a sudden it only works when the truck is off, but once the car starts the amp instantly goes into protect mode. I swear I have go over everything 😩 ugh

My amp plays good on low but when the bass hits hard it makes a rumbling noise what could that be

So I have a cxa600.5 and it worked great for a very long time. I did have a sub problem and since replaced it with a new one, but it worked right away and now it doesn’t work at all after a short drive. Could it have blown that fast?

Great tutorial, followed step by step and I have no measurable AC output from the speaker wires. I don't know what to do next.

How to tune amp if u have two bass knobs one for amp and one for digital processor

my amp is at 18V but the batterie is on 12V why is that

I have a skar audio 2,400 watts dual 12 and on the side were the speakers wire goes it says that is 1,200 watts at 1 ohms and I have a boss chaos’s 2,800 4 channel and when I turn my bass up my amp goes to protection mode but when I turn my bass down it doesn’t I want to know what u think my problem is

I have power to all my wires and I did tests on everything except the fuse I checked that and it looked fine but I will check it now, if it’s none of those things what are some possibilities of what’s wrong? I have a mb quart rw-110a with the amp built in with the sub and it’s in protect mode when I try to use it

Hey the speakers randomly will be really loud and then it will go quiter as well as the sub what could be the problem

I keep blowing fuses and I unhook everything but when I go to hook it all back up it sparks when I put it back together and blows the fuses

How would you go about wireing a sing voice coil sub and a dual voice coil together

Do you know how to take the dash apart under the steering wheel on a 2012 Kia Sorento?! To change an ignition?

You did great on explaining everything 👏.

what if the amp has the clipping color solid only? not protect mode

Got a new subscriber, great job on video🤝🏾

My car amplifier have power protection on. I'm getting reading of 12.8V on pos cable but 10.5v at remote. Everything was fine since yesterday that my amp got a little bit of water under the amp. I've check every fuse and power cable. All of them are reading 12.8V. Only thing I guess, is the remote cable. Can somebody have an idea what could be the problem? Thanks in advance

Great advice on the OFC spend a little more save yourself from issues down the road.

my amp keep going into clip mode 🤦‍♂️
