So - this just completely spared me!!! First - the cheapest multimeter I found that looked like yours was $30 at Lowes. But it doesn’t matter because your test helped me pinpoint that my remote wire was not receiving proper voltage. Come to find out, my floor trim was pinching the wire (I know, rookie mistake). SO GLAD I found this video - your videos always help me and this time was no different!!!!
Bravo for comprehensive troubleshooting guide! Tells us how to confirm power, input signal, output signal, speakers, every little step you gave us a way to test. Troubleshooting is mostly breaking down the needle in haystack into smaller and smaller haystack. Divide and conquer. Exactly like how you showed us how to check for power, then if that is problem, what to do next. Next step to make haystack smaller. Trace cable. Check fuses, etc.
I don't know why it was so hard to find info like this. I was looking to see if the OEM amp is supplying signal to my subwoofer but for some reason I wasn't getting voltage right at the terminals on the sub. Finally, I understand now that V squiggly is Voltage AC and that I need to test for VAC instead of VDC. Nice! Thanks for the info all in one video.
Guys i spent 2 days trying to set up my godfor saken amp and i could not get it to turn on, but i finally realised that the Remote wire was somehow messed up and no current was getting through, i did it bois, it worka
At 0 Ohms their actually is a connection, a short circuit that is. What i think you are trying to say was the multimeter displaying O.L. meaning Over Load. Than the circuit is open because the multimeter can't measure the resistance in open air ;-)
So, I just installed my amp and speakers In my car, and I'm having an issue with the amp turning on. Whenever I change where my ground wire is bolted in at In my trunk, the amp turns on for about a minute and plays. After I stop giving the car gas or shut the car off and turn it back on, the amp doesn't come back on, until I move the ground wire to a different location. I know my ground connection is good metal on metal polished so what is going on here, please help.
i have brand new out of the box, enclosed subwoofers and amplifier. I’m not sure if blue means its in protection mode or does it mean it’s on. Sadly neither devices came with a manual, and i’ve been look everywhere. I cannot find anything on the amp. I even went as far as replacing both power and remote turn on wires, and still no bass. please help. 🙏🏾
There’s a setting on aftermarket receivers that can turn off pre amp outputs. If your speakers are getting power from an external amp. Make sure that’s on or else you aren’t gonna get any sound either.
@@CarAudioFabrication yeah so I had this friend, he has a system where he had a cross over, an external equalizer and his amp wired to his subs, speakers and headunit and I was curious as how to do it exactly
I’m thinking my voltage drops are from the Hondas eld/voltage regulator system, it will not get a full voltage load at a stop for example, however, if I turn my headlights on, AC , etc.. and I’m driving, it puts out a higher voltage. Not sure what to do to keep the voltage up
What if I got only 11.3 volts at the blue wire and over 12 volts at the red wire? It's an after market retro radio and a 200a4 rockford fosgate amplifier. There are 2 speakers in front and 2 rear...no sound. It use to work fine, but has sat for 8 months at least.
Get quality amps and speakers upgrade wiring to match speaker ratings. Lastly do the big 3 thicker gauge power and add an extra ground. Then upgrade battery and alternator. More amperage alternator!
Hey man, love the videos, they've really helped me setting up my sound stage. One issue I have which you may be able to advise- I have an amp in my BMW 3 series F30 (4x100w rms). I used a T harness at the HU, split speaker wires in half, one half went to a LOC which was then sent to the amp via RCAs before finally being sent back to the other end of the T harness to complete the circuit. This obviously allowed for me to use the OEM speaker wire. The system had been working fine for a few months up until last week when my rear passenger speaker blew up (think it was the capacitor as it still functions, though I have disconnected it) and now my passenger door speaker is constantly failing, it will work for 5-10 seconds then pretty much die soon after. I inspected the speaker and it's fine. I swapped the amp output channel for this speaker and interestingly it worked without any problems, pretty much confirming that there is no issues with the wiring. Is it possible that singular output channels on amps can be faulty whilst the others work as intended? I'm losing my mind with this so any help would be greatly appreciated. I'm using 4x 60w RMS Crunch Definition coaxial speakers and the link for the amp is: www.caraudiocentre.co.uk/product_m-in-phase-car-audio-ipa8704d_p-42215.htm Thanks so much in advance
So my amp is not in protection but after a minute my subs stop bumping. I turn the car off and turn it back on, I get another minute of bump before it cuts off agsin. Power,ground are fine 14.7 volts. What's my problem?
Hi that's really a great video. I have underseat subwoofer. When I am turning on my vehicle and playing any song ,the volume from the speaker got very low,however when I remove my subwoofer connection,the speaker sounds get ok.what can be issue?
I just installed a jL audio amp 4 ch and wired it all up and only the left rear speaker plays and it’s quiet. I haven’t touched any of the nobs yet what do I do?
So I bought a home system subwoofer, I get power to the unit and I can actually run signal through it into my studio monitors/ and successfully get sound through my studio monitors!!! but my subwoofer is just not firing at all.??? Has no sound. I have put my multimeter up to it and it is reading 3.2 ohms. Its a 4 ohm subwoofer. Can't seem to diagnose it unless that means its a bad woofer. It has a slight ruffle sound when I press it in really hard... any suggestions?
Hi iv got a targa 2.8kz amplifier works 100% took it to the tech my ground is fine I don't even put rcas in when I connect the amp and it goes straight into protection what else could be the problem
if i turn up the volume to high and my amp getting in protection mode .. so i turn off the head using .. after 5 minutes i can play it again . then got protection mode again .. and you got any issues that would could be??
Hi I’m have a problem with my LC-4-800 I set my gain with a SMD DD1 but as I started to turn the volume up on my head unit the amp goes into protect mode help please
I really appreciate your videos, they have helped me considerably with my installation. I have been buying parts from your sponsors instead of Amazon as a show of support. keep up the great content!
Looking for advice I have mono block 1ohm stable 2x 12" dvc subs at 2ohm Remote ok Power ok 12v + and - at 13 14vdc But amp staying in protection mode light stays red I have turned it of and on disconnected everything and reconnect it all and then also just conected power and remote but (bass knob and rca) not connected and still a redlight how do i fix it?
hey guys have anyone know how it fix a car amp goes into protection mode when you switch to bass mode when ever you rise the volume up it shut down completely
it is recommended that you never go into bassmode. You can change your levels in the back on the amplifier itself. If you dont get the bass levels you wish from changing the settings on the amp itself then it may be time to just upgrade your system. Whenever you get your car tuned at a professional shop you'll notice they never tough the bass levels on the headunit itself.
When my car is in the ACC position, the voltage at my amp is around 12.2 and it runs fine. When I start the car, the voltage is just over 14 and the amp does not work. Why would this be?
Hm, I know my input isn't of any use right now, but a car only ever used the full 12 volts when starting the car, so for your car to be reading 14 is well beyond me, hope you find the answer your looking for!
Hey Mark love the content🤙 just wondering, I have a 2019 F150 and I’m having issues with my right door speaker volume spiking up intermittently any idea what it could be? Thank you!
just a question i bought a cerwin vega 1200w amp thinking yeah this will give me more bass than my 600w sony xplod but when i hooked it all up the bass power was actually a little less than the 600w how can this be when 1200w is supposed to be twice the power i ended up running both amps 1 to each 15 inch sub and works well but just don't get how the 1200w has close to the same as the 600w sony is a good brand i know but i must be missing something here
Funny, but I have that same D6.1200 and just started having a protection mode issue over the last few days. System was fine for 3 weeks. I’ve narrowed the problem down to my front left door mid-bass (Earthquake SWS6.5X), and here’s where it gets odd... The amp goes I to protection the moment I begin to thread one of the 2 screws that go through my MDF baffle and into the actual door (ground). Two things: 1. Why would this become a problem after weeks of protection-free operation? 2. Why would the basket of the speaker coming in contact with a ground source even cause this?
I am only getting 10V from my battery and remote start wire. But the amp is still turning on and in protect mode. Do you know why it's not at 12V I only have a 500 amp setup for subs. I wouldn't think that require any extra power to be put in my car
what about subs output is strong then fades to where you cant even notice them? As in they hit hard and then hardly hear the subs? I have a new alternator and wires ran to the according places.
Hey Mark, great video as per usual, I have a weird one for ya, I have an lc7i in my car, it’s connected, full power & signal going inn & coming out, whenever I plug it into an amplifier the amp goes into protection mode & I get no sound, I’m not sure what to do, any advice, maybe a setting on the lc7i I’m unaware of?
I have an RCA connection to an underseat sub. The subwoofer is working ok but the light on the sub does not come on. Just wonder why this is as it initially worked when it was new and occasionally flashes now and then.
so when i start my car, i can crank my 2x12 inch subs to full volume, i can drive out of a carpark fine. but the minute i get down the road the amp will shut off if the volume is up too high and theres is too much bass. i have redone my earth, everything is fine there, any suggestions?
What is the amps is working but the power light doesn’t come on. One of the RCA’s had a bend on the end of the pen so we replace them with new RCA cables but now the power light does not come on with the RCA’s plugged in but it does work when we unplug the RCA’s the power light comes on and still works
Hi what would cause a 4 channel amp not get power. Reason is no music from car speakers. Fuses are good at the amp. Also when I turn key to accessories the protection mode comes on and off quickly but no power.
I have an Alpine Xi-650 aftermarket head unit. I installed it with no issues using the factory connections. Then I upgraded all four door speakers, and added two kicker subs. I'm running all speakers to a 5 channel Soundstream amp and using the RCA jacks for all connections. My amp is powering on, but I'm not getting sound from any of the speakers. I reconnected the factory wiring and it plays fine. Bought it all from Crutchfield, they thought I might have a bad amp. Sent me a new one, same thing. I bought a 3.5mm cable and connected my phone into the RCA's going into the amp, still nothing. I'm at a loss.
@A. Melbs Hey. yeah, I found out I had some copper showing on one of my new speaker wires from from one of the doors. It was touching metal on the amp and basically shorting everything out. I cut off all the ends cleaning, made sure not to have too much wire showing at the terminals on the amp and reconnected everything. Been playing great ever since.
Why would my 2 amps be cutting out when I hook my phone up to my radio with Bluetooth it happens after I go above 17 on the volume the front speakers that I have hooked up to my radio stay playing it’s my sub JL W7 my jl 6x9 and rear tweeter when I switch over too the radio I can put the volume up too as high as I’d like it’s only when I hook my iPhone up too the head unit with Bluetooth
My mono block should put out 1250 watts on 2 ohm and I do get sound from my subwoofer but It's barely anything, can't hear it while driving. I measured AC volts from the speaker outputs and it's only putting out 10 volts at MAX gain! Is my amp blown?
Love the vids. Keep them up. Quick question. When ever I hook up a fan to the amp to keep it kooler, it cuts off. I've switched wiring , used ground as negative and hooked positive wire directly to the power splitter. Still cuts amp off. Like it's going into protect mode. It's an old skool Rockford 801s amp
Hi nice video but one problem I m facing is my Mono amplifier running fine when I only use MONO amplifier but when I m trying to use 2 amplifiers like one 4 channel amp and one mono amp then my amp work sometime then get off (No protection light on and no heating issue) then after some time it automatically gets on and after sometime again off then again on but when i use mono amp separately it runs all time. can you tell me either proper current is providing to run 2 amplifier or there is issue in amplifier. please waiting for your reply
My Taramp TS2000 Is Stuck In Protection Mode I Honestly i CheCcked Everything And Its Running into another battery . What Could be the issue ? Dont wanna Have too buy a new amp i Checked the wiring everything Is goor
I tested the AC of the speaker's channel on my amp and they are stable but with the bridged channel I'm using for my sub it goes up and down (when playing a test tone frequency so it should stay stable). Any idea what can cause this?
installed a kicker key 4 channel amp. I have a low volume hissing noise. The noise has stable volume no matter the radio volume. The noise is still there even with the inputs disconnected and the engine off. My grounds are confirmed good. And my gain is all the way down. Also my amp chassis doesn't touch metal where it is mounted. Is there anything else i can try to remove this sound? It is not very loud but it is there and before the amp install there was no noise.Thanks.
Any idea why a stereo with integrated amp (sony ax7000) would do this? I've tried every idea on the internet but it still happens. Also happens to a different stereo I have with integrated amp as well.
I just installed a full system to my stock head unit. Now my blinkers are LOUD!! and there is a constant buzz. The lower line is run away from speaker wire. Any ideas what I should check?
I have a old Alpine amp and my fuse holder is in bad shape,the prongs are bent,the housing is cracked,surprisingly the amp is in good shape,i know the housing is soldered in,where could i find a new housing? i have a crystal clear picture of what one in good shape looks like,any input from the masters out there?i wanna save the amp, i have plenty of them, just attached to this one,lol, thank you for any input.
Hi Mark, I have a 4 channel jbl stage a6004 560amp, I've wired up the rear speakers and added a sub both via high level input, but I seem to be getting a power drain and the speakers cut out temporarily whenever I accelerate or brake, power steering etc.. or use anything else that uses the power from the battery I've even replaced the battery with a more powerful one. I've checked all connections, ground, remote etc and all is good Could it be anything to do with the power cable that I'm using? Many thanks in advance
My amp is consistently in protect mode but while I'm driving it will occasionally switch out of protect mode and I can hear bass coming from my subwoofer, the voltage for my amp's power and ground is 3 dc volts is this my issue and if so how do I fix it or figure out why my amp is not receiving enough power?
Hi Mark ... you are great, what about Latinos or Spanish speakers? it would be nice to have subtitles or a channel with dubbing ... it's just a suggestion, I love your videos
My speaker amp goes into protection mode everytime i turn on my car & i just have to disconnect the remote wire & connect it back & i dont have any problem. Its just when i turn on the car. Would appreciate any help. Its just the speakers amp. Never had that problem with my sub amp
HELP! Doing the Blue and Ground wire test, I’m getting 11.75 volts and my fuses are fine. How can I fix this to get 12+ volts out of here? (Power and Ground comes to 12.12 volts)
