I need some help finding out how to ensure your car supplies enough volts to truley power up your amps. Does a Farad Capacitor help this? Thanx in advance.

no, a capacitor will not aid the charging system, if you want to know why..run a search...

what amps are you running?

Hmmm...about 1500 under-rated class a/b watts -- Unless you have a very big stock alternator (120A+) I would definitely do some research on an upgrade.

what kind a car do you have? it is the sub amp that will really put a hurtin on your alternator, but w/800 watts i just don't see it happening. i'm running ss (sig) and my alternator smiles at them. i have a 135a stock alt and will only be upgrading because of the extra (2nd) 1600w i will be installing in june.

as i understand it, even including all your amps you would only need a 133a alt (watts/volts).

like he said, if you have around 120 amps (usually trucks will have like 135 or somthing)

i wouldnt worry about it.

do you know if you are dropping volts? what kind of wire did you use? 4 guage? 0 guage?

any pictures?

I have a SCION XB (yes the wierd box). I am upgrading the wire to 0 guage and was thinking of adding Caps to all the amps... only have one on the sub amp right now.
