wouldnt be surprised if it was a bad ground.

i go for this one aswell, or maybe the cap is wired wrong or theirs not enough supply power? maybe the amp shuts down when the input power is to low?

bah, i still say check ground first, and is ground same size as power?

then throw out the cap.... its just another thing t go wrong, and double triple check all the wiring! that means check everything three times, then do it again three times just to be sure...

oh thank u so much to all u guys for helping me out.....i m gonna do all the things ritenow and check wat is wrong....as along as i think its either cap or either its ground....so i m going ritenow to check up and wil post again if something goes wrong.....thank u again to all....

and ya i jus bought SPIRAL GRAD CAR BATTERY for 200$....and i don think so if power supply should be the problem...wut do u guys say?

what is your crossover (LPF) frequency set at?
