I glad somebody actually cared to explain this too ppl 💯 very well put .

Sweet d4s, jp, dropping knowlage!!

Sounds like it doesn't hurt to "over-engineer" your Cars electrical Setup for Car Audio - if One can afford to, THIS is the type of Videos that most channels do not touch on. Thank you for sharing this info

I'm staying 12v YAY!!!! Woohooo...👍😃👍

I'm sticking to a 12v setup. I love my Sony Mobile ES speakers and XM GS4 amplifier, the sound is so clean and crisp that I just want to sit in the car for a few more minutes after parking it to enjoy the music. I plan on doing a Fi Neo 3.5 12 inch in a sealed box up to a 2k amp with a stock alt and 0 gauge big 3. Then put in a 240 amp alt once the stock alternator is worn out.

Thanks JP awesome video. I'll be upgrading electrical soon. Need to upgrade alternator and battery but will remain on 12v. I am running less than 8k watts total.

I run 2 separate 12 volt systems. Stock alternator running the truck and the door speakers. CES 370 Charging 80ah of lithium for the bass side.

I didn't know about most of what you talked about. Thank you Professor JP.👍🏾

BROTHER THIS IS AWESOME!! LOVE THE KNOWLEDGE YOU ARE DROPPING

I just did a system install for someone yesterday and explained the exact same thing I'm going to send them a link to this video for confirmation!!!

Thank you I've been so confused for so long and I have no business I just want at least 5k in a 18 Silverado I was so confused to how I'm going to upgrade my electrical I know how I just didn't know what to do and what way to go with the alternator and battery and stuff

Just the info i needed been lookin into this . Thank you

From experience yeah don't slap a high putput alternator without knowing what your doing. I fried my Escalade like a noob. Great video sir. Wish I had seen this before. But I learned a lot.

I’m running Skar DDX10 d2 with skar 1200.1 in a 6th at 1ohm. Headlights dim horribly. Did big3, no progress. So ordered the Mechman 240. Now I gotta change 4awg to 1/0. Haven’t popped any of the 100amp anl fuses yet at full tilt. In a daily driver.

06:21 screen says lithium but those are AGM batts. "D" is AGM with XS.

I See u 9years I miss demo video For malaysia

Thank you for the information 💪

Great explanation JP. D4S ftw. 👍✌

I have a 2006 mustang gt I have full 0 gauge wiring ran on Taramp smart 3k and for mids and highs I have a 900 watt ct sounds with yellow top under the hood and in the trunk with big 3 done and currently wait on 200 amp high output alt that hasn’t came in do you think the alt will help with my voltage drop????

Great vid jp!!!!

Mechman doesn't even make an alt for my vehicle. imagine that.

Thanks for the video. It answered my questions I had👍

Answerd all my questions thanks jp your the 🐐

Still my favorite shop for car audio. I'm down with D4S.

I just put in a 320 amp alt at 15v and its resting at 15.1 - 15.3

Thanks jp. Always learning somn'

Great video

JP, WILL YOU please make a video on how TO DO AN EV VOLTAGE UPGRADE for an after-market system that’s around 3000-5000 WATTS??? This would be important for those who wish to upgrade their EV FACTORY audio system.

Thanks for explaining that in a way that was easy to understand

Thanks for making it clear.👍👍

Great information well explained thank you.Maryland showing ❤️

So the cool thing about my car is with the stock ECU it can handle up to 15.9 volts of charge I pulled out my stock 130 amp alternator running off of the ECU and I ordered a Brand X 390 amp alternator and had him set it up for 14.8 volts constant internally regulated so it is not controlled by the car's ECU anymore because that fluctuates then I built myself a 6S Ying long 350 amp hour Bank of lithium

Thanks for your help and knowledge

Very important information JP thank you appreciate all this im a beginner so trying to absorb all the know hows..🤣👋

Great videos and knowledge mr price.

Thanks

Oh ya!

Nah, I really appreciate this. thank you.

Awesome Video and explanation.

1:30 XS Power AGMs (ex. D3400 instructions say to never charge over 14.4 or 14.5V for more than 5 mins)

Great informative video!! Thanks for sharing. I learned something today! Lol 👍

Good lookin out on that info

Thank you. I’m very new to this and this helped me understand what I should stay with for bassing everyday. Can I run two batteries (one for subs amp and other for car stuff like lights radio) and run them to one alternator? Or upgrade the alt for the two batteries

To keep car computer and oem accessories @12 volts but your amps at 16 volts using just one alternator.. Do install a 16 volt alternator and your 16 volt battery banks for the Amps, but a 14 volt "Down Step module" from such alternator to your regular oem stock battery. And do Run your 16 volt battery banks directly to the 16 volt alternator terminal.

How to run 2 diff voltages in a vehicle that fits only one alt total? Voltage step down to run car and high voltage for the build? Like SMD used in his Tahoe?

Asking this before watching, if I’m charging at 15.8v do I need a step down converter to run my SUV’s electrical components? Like the radio, lights, dash, ac….?

Love the info you put in your vids. Im currently wanting to upgrade my alt plus big 3. Im not looking to do high voltage though. Im trying to stay with 12 v. Ive been eyeing Jp amps for awhile now im looking to have around 4000 watts for the bass end and running a 1200 watt on my midd an highs. Do you think an alt upgrade an big 3 could handle that load? Also will you be coming out with a more powerful JP amp

What needed for a 2005 chevy tahoe z71....after market stereo.....altenator and battery..

Thank you!

Great video!

Dropping gems

So I'm pushin 2k and so you're sayin that I don't need to voltage up?? Thank you for your info JP

A question I've always wondered is at what kinda power should you add a cap? Im running a real mild setup in my 2011 silverado 1500 5.3. I have dual battery setup I did under the hood with dual 12v Duracell golds. Pioneer 1300nex hu, Taramps 800.2 feeding 4 factory size prv neos in factory door locations, and a tinpano 1400.1 going to 2 10s.

*I took my engine out and just run 16 alternators now*

my f150 gas a stock 220 amp alt and i just put in a x2power agm 81Ah watts the most watts i can run safely???

Demoing into 12’s is ok? As long as voltage stays 12.4 and above? Charge at 14.8 but under heavy long bass notes I’ve seen 12.9 I try to stay 13+ but if mid 12’s are ok then I’ll stay in it longer. I got a 192ah headway backed by 370 singer and a 270 Ohio Gen alts….6 runs power and grounds (3+3-) straight off alts to rear bank with all 2/0 welding cable.

Question: My 79 Mark V died in The middle of the street. I found that the alternator was bad, and just not charging the brand new battery that was installed (only 2 days before). Tested the alternator while the car was running, and it was not charging the battery. I have an aftermarket sound system in this car. It's a 800W amp split between 2 12-inch subs. Should I change my factory alternator which I believe is 60 to 70 amp, or should I get like 100 amp alternator? Or, will that burn my battery, and should I just stick with a 60 to 70 amp alternator? Any good advice would help, thank you in advance.

JP, does Mechman make an alternator for a 2021 F150 yet?

Hey jp da man

I have a 2014 silverado and am wanting to go with a jp23 v2 amp pushing 2 sundown sa 12s v2. I was thinking of getting a 320 amp alternator. What all would you recommend for this set up?

Totally agreed.. 👌💪🎼🔉 all sayed on this video if ur a basshead...

Thanks jp

Great video I have a question I have 2021 Corolla ,if I get a alternator with 320 amps but the computer charge normal will be worth it I'm asking because my car have only 1 wire for functions and I been told if I want higher voltage my car will look like Christmas tree😂 so if I get and high output alternator that charge with computer but more amps will help me?

Hey What's Good jp i been watching You're KZfaq since u 1st started on the Tahoe riding by the clubs but i was trying to get some real music and brought a Taramp 20k hv it needs 16volt's to even turn on i Don't know what or how to start off

I can’t give this much credit unless the original “autozone” battery was brand new 100% charged, but ima get an xs power battery for my application anyways.

We need video on semi some of us are bass heads.

What will a need to run 2 xtr 2500 watt Orion amps on 4 15's q class subs in a 2013 suburban 1500. Right now I'm running 2 q class 12's on 1500 watt. I did the big 3 but I know I will be changing the alternator and battery.

💯💯💯

Stupid question but I run (2) Skar Evl's 15's and a Taramps 3k HD I take it that I'll need a high output alternator?

I’m running yin long 80ah only no agm or acid battery Im running 6 10” skar evl’s with each getting its on amp (pioneer 9601) so you said you charge to 17+ volts. I used a limitless lithium charger that only charges to 15.5 would it be good for my system to charge to 17v I already burned out my factory alternator and JS is building me a 410amp since July on back order thanks for your time (2007 Hummer H3).

Thanks bro 🙏

I am looking for a high output Alternator for a 2019 suburban i run a lot of lights and i just want something to replace the stock Alternator

Very solid advice JP! But that only covers American made vehicles. What about foreign makes like Honda Nissan Toyota and Hyundai that have really small stock alternators that are lucky if they're 110 amps, i had a very difficult time finding a custom alternator company that was able to quote me a price on the alternator i needed for my car and the size of the build i was doing.

Im gonna be running just one 1500 watt amp on an 8" would I be good with just a battery upgrade to a d3400?

I have 3 alternators for my audio system separated from the cars existing charging system, no way im putting al the surge on the cars electronics(OBD transmission, body and engine control boards!)

So what would be your opinion on what amp and battery should I used to push my single Deaf bonce 15 " DB-SA 305 D2 subwoofer I already did the BIG 3 and a 300 amp high output alternator?

Hey how's it going? So I'm kind of just getting into getting a real sound system in my Ford Explorer I've had many other vehicles with just random amps and subs and boxes nothing matched just Jimmy rigged and I got through it through those years in high school and what not but now I'm running two 12 in DVC 4ohm subs in parallel to a kicker 1200.1 monoblock amp subs rated at 800rms and amp is 1200rms at 1ohn I was having issues with amp cutting into protect but I was off the running cheap 4 gauge CCA power ground wire now I'm hooking up the new ofc 4 gauge AWG amp kit now my question is since I'm definitely trying to stick with 12 volt system do I need to do the big three? Or even upgrade the ground on the actual battery under the hood? Or put some kind of little capacitor in there? I'm hoping possibly just putting this ofc for AWG wire in will do the trick! Let me know what you think it's a Ford Explorer so it's already got pretty big alternator but it's all 12 volt and I would like to stick with the 12 volt and I know I'm running 300 w lower than the two 12-in subs are rated RMS at anyway I would appreciate if you can drop some knowledge on me with this issue I'm hooking up the new ofc wire Saturday coming up I'm already getting all the ends crimped on just got to rip out the old and put in the new but yeah any info you can give me on that I'd appreciate it thanks a lot JP keep them pumping That Bass brother!

Assuming my ecu controls voltage, how would I slightly bump voltage? Say to 15.2? Running LTO bank, Mechman 240 in a 2012 ram cummins.

Maybe you can answer my question....because someone named Brandice refuses to. Is the OFC wire simply better no matter what the application, than using CCA wire? Also, I want a Big 3 kit. Can you make me a 4 guage kit using OFC wire? Its just a normal every day driver with a 1,200 watt amp, one 12" woofer and MMats speakers for mid range, door speakers and two tweeters. Nothing carzy. But I have a high horsepower engine so I wanted a better 145 amp alternator instead of the factory 95 amp. So I need a 4 guage Big 3 kit. Thanks.

Mechman 240amp alt sitting on my bench in the garage...don't even need it atm and they are kind of a pain to put in second generation Highlanders. Got it a couple weeks ago and I'm being lazy. I'll get it in there eventually. 2,000 watts at 2 ohms isn't pushing my stock alternator on 2x Northstar AGMs very hard anyway. When I start my car it's 3.9 volts and it drops down to 3.1 when I'm hitting the subs hard at idle for long periods. That isn't too bad is it?

I dont any alternators for a 98 ram 5.2 on your site

Hey everyone I have a 19 Camry with a 240 autotech and the voltage control module I've been running it at 14.8-15.0 with no problem BUT I just ordered a 29AH SCIB bank from NORTHWEST LITHIUM and i installed it yesterday and as soon as the voltage went over 15v the car started beeping and saying charging system malfunction on both the dashboard and radio screen i know it's just the modern version of a battery light and was told i could possibly see it when initially installing the alternator is it ok for everything to charge that high and what are possible solutions to give my car a lower voltage while still seeing 15.8 at the SCIB bank in the trunk mind you this is a sedan (19 Camry) with very little room under the hood and I have no clue where to look so I think the dual alternator is out of the question unless someone can point me in the direction of someone who knows how and would do the custom work of the dual alternator setup

What would happen if I put about 16v of ultra capacitors after headway bank? I just have an agm under hood, big 4 and 250amp singer which unfortunately is as big as possible. And a 500amp isolator between under hood battery and 96ah headway. Any help from anyone is greatly appreciated I'm trying to boost up my voltage right before the amp since my alternator is kind of small for what I want to do I'd have four on there if I could

Do you have a plug and play Alternator for a 1987 Buick regal 5.0L this also sends a signal to the dummy volt light inside car. 250 amp or under 300 amp

I'm running 2400 watts should I get a high output alt

And yes guys you can still compete with 12v systems but EXTREAM COMPITITONS you can use 14.16.ect.and put up huge numbers 165+

I need a mechman for a 2012 veloster base model

So I can run a 6k Sundown Salt amp with stock Alternator with 0/1 gage wire with big 3 upgrade? Maybe extra battery

I'm not into audio, but the electronics are cool!

Hi sir I would like to know if I were to build a car audio system in my house does a power supply work the same as like batterie does if I were to join 4 50A power supply would that give me a total power of 200A

Also to mention if you choose to run a 14volt system to run the vehicle and sound system you gotta make sure the higher voltage does not take out the factory electronics. Most newer vehicles can't handle anything over 14.4volts. But a good bit of older vehicles can, if you pop the ECU you are gonna be in a nasty expensive pickle. If you don’t understand any of this at all just stick with the standard 12volt system. And don’t listen to the 99% of the dumb fucks on Facebook or other social media audio pages saying "oh its easy just buy this or do this"... Do your own research and learn the proper way. Just a reminder chart: 12volt system charges at 14volts. 14volt system charges at 16volts. 16volt system charges at 18volts.

Wat would be recommended to power a SFB8000

ihave 2 12s and a 2400 watt amp do istill need to upgrade my wires and alternator?

Ok I have a stock 150A it's not enough i need a stronger what do I need ?

i had my battery and Alternator went out. do you suggest a better Alternator. im not running comp setup. just a daily 2 10" sub with a 850 watt amp. i was told my subs killed my Alternator and battery and that if i wanna run subs in my car i need to have an upgraded Alternator. is that correct?

i just bought a 500 amp mechman but do i really need the external regulator adjuster?

When my car is running my headunit reads 13.9-14.2 … is that not normal? Especially if I have the volume up a bit, if not it’s always 14.1-14.3. But I never see that 14.5-14.8

So if you don’t know what you’re doing don’t learn what and how to do it? So how is one to learn if they don’t start somewhere

AWESOME INFORMATIVE VIDEO, even though I surpassed this level last year, still awesome to see you post tip vids like this.

2021 F150 5.0. No high output alternator? I can't find one anywhere. Unbelievable.
