WHY YOU NEED EXTERNAL REGULATION FOR YOUR ALTERNATOR 

hey man I feel like you made this just for me

Good Video JP. I enjoy your your little lesson videos and even learn a little bit.

Right on, thanks for info jp! 👍

Keep up the great work.

NICE INFO BRO!!!

question, the jp23 stopped playing for a while and the temp light was on, but it was at 100 degrees on the remote. this was the first time playing it with the back seats up usually theyre down and it will get even hotter than 100 degrees and it has never temporarily cut off. so im not sure if it was cause i had the seats up even though it wasnt too hot on the remote, or if it was detecting the subs temp? which also werent hot barely warm on the dust cap theyre 2 audio pipe bd4 12s at .5 ohm on the jp23

Will this work in a 2021 rav4 with with the proper alt? I heard the oem in these new cars restrict volts at some point.

What do I need if I'm just upgrading my factory alternator to a 300 amp? Do I need regulator and any other special equipment??

Thanks for b the info JP

hey jp thanx for the info cause I want to run a 16v system when I get two wolfram 9000.1

This is Kelvin I have a question to ask I have brought me some sundown E65CS speakers and some E69CX what would be the best sundown amp to run those

Question, I have 4 Sundown SD-4 12s on a SFB-3000. I'm trying to get my mids and highs together. I have 4 DS18 Pro-X6BM, 2 DS18 Pro-TW420, and adding a DS18 Pro-XBM6.4. I bought a SFB-500.4 to run everything. Is this ok, should I buy multiple amps for mids and highs? Space is kinda a issue, because its going under a truck seat. The subs are behind the seat. So the amp rack and extra battery is going under seat.

What is the name of the pigtail thing thing you were speaking about to boost voltage

Thx for that info

Will the d3400r fit my Mitsubishi lancer 2016

Will the blue unit work for any aftermarket high output alternator???

I have a js alternator 320a and I'm running it in a 91 jeep Cherokee that is already regulated by my ecm and it is severly cutting back my voltage at times, will the mechanic external voltage regulator work well with my Js brand alternator. Also I already purchased the regulator and just checking before I install it so any feedback would be much appreciated.

Can this unit be used to dial DOWN voltage? I have a 370 amp Mechman alternator and it is great 99.9% of the time. Its a 2 pin unit and was on my 2012 Duramax 6.6 diesel Silverado. I've taken it off because upon start up of the engine, the voltage fluctuates WILDLY for about 30 seconds to a minute or so. I've seen the voltage spike into the 17v area during this time. It settles back to around 14.8v after a minute or so, but during that time, all sorts of weird stuff happens.... Dash lights for things like BATTERY, CHECK TRACTION CONTROL, CHECK STABILITRAK, etc as well as the speakers make loud "crackling" sounds, like someone has applied power to them! I'm currently using a smaller 145 amp alternator (not a Mechman) and have not been having any of those issues. I love the Mechman, but am concerned it will harm my two Lithiumax Race9 starter batteries.

JP, I’m only running one new alternator from MechMan. Can i use this device on my just one Alternator?

Hey! I bought the sfb5000 and 1000.4 as well as a limitless cyber 12k I’m gonna run 2 Rockford t212d4 subs in a 2001 Hyundai Elantra 2.0 I will purchase a the upgraded alternator and big three kit from y’all my question do I need the external regulator as well? The car only has space for 1 alternator .

Hey JP i would like to build an alternator for a 2008 honda fit. I believe its called honda jazz in America. Anywho, the alternator im running is factory n i think its a 70 or 80 amps but i want to run a 12k amplifier. So whats the cost for an alternator built n an external regular altogether?

I have a question I have a xspower battery under from hood and two 12k lithium batteries in trunk can I use a dc dc charger to charge my 12ks while I'm driving around bassing

Will an external regulator work on a 300 Amp js alternator

What happens if you try to regulate 3 alternators from 1 blue external regulator???

Whay do think of mtx terminators 12s

if i have 350a high output alternator with regulator external, how high can the voltage be set, what will happen if set above 15 voltage, will my agm die, or it is still safe and i will get more power? Thanks.

Good info jp

I have 2011 town and country and it stop charging got new battery and alternator but still not charging I bought alternator regulator kit do you have or know of diagram of how it should work?

Good day am having another type of problem.. In my 2002 honda accord I put a DB electrical 220 Amp alternator in but why my sound system is on my voltage bumps up to 16.5 or 17.1 the drops back to 14.4. It does this numerous times and the amp goes in to head unit goes into protect mode unroll the voltage decrease... With you regulator socked this or control the voltage robot doesn't go that high and burn up my system...

I have like 2000 watts on my system is it worth it getting a mechman alternator and a 3 big upgrade?

Does the alternator pump up the bass or just power for the battery?anyone?

Good info thanks

2017 Ford F-150? Please help!!! I have mechman 370 and voltage still running around 13.3

My regulator is bad can this lower the voltage to 14v the alt is charging at like 16 it's too high for me

What alt does this work for??only mechman?

Does it go to 16v

Hello JP, I’m new to the car audio, and I’m running 2 Soundstream x5.12 with the txp1.12000d amplifier. I have two agm batteries one is the starter and the other is the house battery. What would be the right way to wire them up. For now I am still using the stock alternator. Which is installed in a 2015 Silverado 1500.

Can you do a video on how to know if you need a bigger alternator so I don't fry my electrical system in my 2018 car. I feel this is overlooked nowadays. I want big subs with big power which needs a big amp. I don't know how to go about it without messing up my electrical system. How do I know what the biggest amp my current electrical system can handle safely. There are some videos about this but since I'm not a full time car audio electrician I never understand what they are actually saying. We need a simple step by step process. This is why many do not buy more powerful amps nowadays.

Love the great tips man

😁👍🏼 ever one good luck on the tweeter giveaway...

I have a 390 alternator internally regulated. Can an alternator shop take out the internal regulator so I can use the external? My volts start at 15 on stertup but drop. Sometimes Down to 12.5. I drive a 18 Colorado 2.5 Just bought the jp43 amp. I have two bAtteries done the big three. Please help

I need and alt. For a jeep Cherokee sport 2.4 your website doesn’t say if it will fit the Cherokee sport or not

But what if ur ecu says no

I have a 200 amp 14 volt alternator will that make my 12-volt battery go bad or do I need to increase to a 14 volt battery

Why would you need more volts?

Wow, lots to change if you want to put a decent audio system in your vehicle.

I have a PCM module (US Alernators) that pins voltage at 14.8 when system is on, but throws up a "check charging system" notification every time I start my car. That's kind of annoying. Can these circumvent those error notifications?

Accuvolt can be used with any charging system. Use a quality American made, not assembled alternator

New JP Amps, When?

👍

I've got a self exciting alternator wish the wife was the same way

17 volt

I have a 390 js in a 08 ford fusion and it would not send volts right at all I purchased a adjustable voltage regulator from us alternator I can make it 12.4 all the way to 15.5 without the regulator it would bounce 12.9 13.5 13.7 .13.3 and that was idle and no load or reved these things are awesome JP man I have been asking you about them blue waffles for some years now tha ks for the info

I was so happy until he said the alt has to be modified for external regulation

You don’t need any of this ! Sorry jp but I was chasing my tail trying to figure out what system to get to bump my voltage . Then I had a major duhh moment I’m running a 75 cent$ diode on the alt sensor wire with a switch volts are 14.8-.9 with it on , with it off 14.3-.1 . Ran this set up on stock alternator and high output 320amp alt. Will work with any alt with no modifications. This stuff dose the same thing as just using a diode it just lowers the voltage on the sensor wire. I would bet the plug in dongle from mech has just a diode in it! Pick the diode do you want to achieve target voltage. i used one that drops .5 volts

Dude....this dude ..((..robot underground)).. bashing...you all.. Need to check his channel out

You did not tell the truth that if you increase your voltage upto 17v and your electric system is 12v then it will blow fuses or 12v electrical components. Pls calrify

I would use caution buying anything from Down4Sound, I have used them for a couple years and recently ordered a 1/0 OFC amp kit along with a 4 gauge OFC amp kit and 6' of 8 gauge OFC speaker wire. My order said it was at my door via email and when I got home it was gone, I believe someone stole my package. I contacted D4S and let them know what was going on and I am basically being told I'm on my own and they will not replace it. I always had respect for this company but now I will never order from them again. I have ordered thousands of dollars of equipment before and now a couple amp kits go missing and now I'm out of my money. I'd definitely order from another site!!!!!!

I ordered a "Excessive Amperage" alternator direct from the manufacturer. Couldn't find my application on your page. I'm not upset about that. What does concern me though is there are quite a few videos essentially saying those alternators are, let's just say, defective. Now, with that being said, you, being one of their distributors, do you, Jonathan Price, stand behind their product? As far as quality and reliability goes? I haven't seen you do any videos promoting "Excessive Amperage" on your channel.
