1998 Chevy S-10

X2 I feed my cvrs a good 450-500 a piece daily for about a year now.. No issues

less than that with a brutus

The above pic is Ohms law pie chart.

I will assume that you want to calculate for your system @ idle:

E = Volts on your batteries @ idle

P = Total RMS watts coming out of your amps

I = Alternator output in amps @ idle

R = Resistance in ohms between the power source & the destination

When you said you ran 5000 watts RMS for 15 minutes & the lowest your voltage dropped was 13.6, I can believe that with 3 D3100's. But if you would have played it for another 15 minutes, your voltage would continue to drop. An alternator putting out 150 amps cannot efficiently charge 3 huge D3100 batteries while they are being used to power an amplifier putting out 5000 watts. I'm not telling you that you can't hook up several batteries with 1 alt & play loud music. All I am saying is that your charging system (alternator) is not designed to handle that load, will not effeciently charge your batteries & if you play your stereo for more than a few minutes @ a time full tilt, you will damage something.

I don't know the specs on your amps, but my T3K's need 14.4 constant to run properly. anything below that & you are asking for trouble. Almost everyone in the car audio is "banging on a budget". Out of 100 systems out there, maybe 1 or 2 is actually done correctly. Don't get it confused, burping a system & playing music @ full tilt for an hour are totally different.

Ohms law isn't something that I just made up, it's fact.

basebalz13, I have noticed you have been posting some stuff about burning up a ton of alternators.

If you want to get 5000 watts out of your amps with no power problems & not burn up any alts, you will need 347.22 amps @ 14.4 volts for your shit to work properly & not blow up. Also that 347.22 amps does not include the amperage needed to run your car, that's probably another 60 amps or so. Adding batteries is only a bandaid not a true fix. If you have an adequate charging system putting out the correct # of amps, you don't need a bunch of batteries.

I understand that not everyone can run quad alts. In those cases, batteries are the only alternative, but that doesn't make it right. There are some batteries out there that are specifically designed to work like a capacitor & release energy very quickly. Kinetik & battcap are some top brands. The bottom line is if you have the option of 300 + amps worth of alts or 3 batteries, go with the alts.

Complete waste of money imo, especially in the long term. But if you can afford it why not...

im talking about a multiple alt situation btw

Actually its not a waste of money. if your gonna buy a nice system, pay for a nice alt setup as well so your system is less likely to be damaged

Here are a few pics of the box & the CNC machine that cut it out!

Gotta love a CNC machine!

lol maybe you should of read my other thread that you posted before posting

it was bad alternators that continued to fail because of the alternator,

everyone thats knows what they are doing knows how to control the volume knob,

also you never see full output on the amp during daily bangin, consider imp rise and music never hits full output(well rarely)

yes you keep statin "ohms law" lol i know ohms law very well in college for electircal engineering so i THINK i know what im doing

if you dont feel safe runnin that much power then maybe car audio isnt something for you?

also who plays full tilt at idle? your just asking to get a ticket because 90% of your average driving time is spent at idle

Gotta love a CNC machine!

lucky wish i had equipment for that in my builds

[GIMNICK]

lol everyone wishes they had a cnc machine!!! and it took 4mins to cut every piece out for my box and only costed $65.00 to cut everything i needed...

maybe where you live

Well we got the back wall & roof covered with dynamat. We installed the Pioneer premier F90BT & ran RCA's, speaker wires & nav antenna. Hopefully we will get the bos put together tomorrow.
