How and Why to run a 14.4 volt Car audio Charging System 

You are really educating the car audio community

Thank you for the information! The only caveat to higher voltages is the fact that most power supplies are not regulated so rail voltage increases hence the higher output. Most transformers are wound 1:9 to 1:11 with rail capacitors ranging from 160 to 200 volts. Unfortunately, most end users do not know this and then blame the amplifier was faulty when the 24N40s fail.

Great video

so you use 14.4volt batteries ......... 1. what chemistry gives you that voltage and 2. how you gonna charge them?

Standard alternators charge at 14.4-14.8V. Do you need special alternators to keep 14.4V batteries charged?

I'm considering a 370 amp alt for my 2002 tahoe. Power an agm in the spare spot under the hood. Amps to be run, pg xs 6600, 4300, 2300 and 2 2500. Stock will stay the vehicles 130 alt and agm. Sufficient? Third battery in back?

So do you suggest a higher amp alternator and 12v battery setup? I have the big three and everything is 0 guage wiring. With a stock 130 amp alternator and stock battery and a 12v 100ah deep cycle in the trunk. My voltage always stays around 12.5-12.8 except when that deep deep base hits its dropped to the 10s. So what do i do? Upgrade my alt?

Nicely put this also is true in any electrical application even your home electrical. The electric company charges you by the amount of amps used and not voltage and the higher the voltage the less amps everyone always assumes that 220 v cost more to use in reality it's cheaper. It pulls half the amount of amps then 110v no matters what it is. Most people don't know that A car amplifier is actually a very high voltage they have basically a built in transformer the only reason a amp is 12-14v is so your car can actually power it but its stepped up in the power supply to a lot higher voltage to power the actual amp board. Sense the income power on the income is at a way lower voltage the amps that are pulled is pertty high usually 100-300amp . A amplifier would be extremely small if it didn't need to transform the power the currect voltage to the amplifier board.💯👍✌️🤔🫡

Hi @ CAE. I want to ask about running multiple battery system. I heard many different veiws. So I have 1 batt (bosh) in the engine bay and 2 batt (odessy) in the trunk. what would be the bettery way to connet the system. 1 wire front batt to rear batt and 1 wire alt to rear batt? or should I just run 2 wires from front batt to rear batt? All AGM battery and stock altinator. also running dual imputs into my B2 5000watt sub amp. Would there be a voltage difference in any way?

From a Pot head to a Bass head thanks for the education.

So I'm running 12v agm system @ 60ah (subs) with stock alternator 14.5@ 90amps and rear agm @ 22ah (highs and mids). The lowest they get are 13.2 at full tilt for short times (street driving). After a while it'll kick up to 13.7 to 14.1. I know I need more ah. My question is.. does this seem to be a good setup until I get more storage or should I get H.O. alternator next? Thanks
