can a stock alternator and some random duralast battery in an 82 trans am power a 1000w amp and a 2000w amp? 1000 to mids and 2000 to sub

 

It would depend on the how much draw the amps actually require. I know my 2 JBL BP1200s (1200 watts RMS) will drop voltage under 13.5 if I turn it up any higher than 14 volume on the head unit. I have the 105 Amp Output Alternator from Autozone and I put a overdrive pulley on it.

Hook it up and try it. I imagine you're not going to be able to crank it all the way up without the amps clipping. Upgrading the wiring grounds, alternator wire to battery, and etc ahead of time will help.

 

what do you have for amps? a lot of them rate themselves WLS (when lightning strikes) and are actually quite a bit lower in power, not to mention thats *maybe* peak power, which you will almost never hit.

but, playing devil's advocate and assuming those are true numbers, your stock wiring and alternator are no where near up to snuff for those amps.

in a perfect world (100% efficiency and no losses anywhere), Wattage = amperage x voltage. so that "1000 watt" amp would draw 69.4 amps at full power at 14.4v. guessing that RMS is normally stated about half of that, figure about 35amps just for that amp. with both amps, you're looking around 100 amps.

 

run a cap!

 

your gonna have some funky lights happening. On one of my old systems the lights would flicker when i had teh sytem on. I was only pushing about 1500 - 2000 watts
