I am currently running 1100 Watts @ 1 Ohm to a pair of subs and when I turn up the volume to about half the music goes quiet after a bass note for a second or two. I watched the meter on my 2.4 farad Cap and it drops below 11 when this happens. If i'm correct that is the voltage of the battery and cap since they are wired in parallel and the battery should not drop that low or I could damage my amps. I am told everywhere I go that I need a higher output amp to fix this but no one is able to help me find a bigger alternator that would fit. The stock alternator for my car is supposed to only be 80 amps if I'm correct. I have found 2 places that could produce an alternator for my car but personally think 600+ is too much to spend on a custom 170 Amp alternator. I would much rather find an alternator for another car that would fit if possible.

Anyone else run into this problem? Solutions?

 

if you have a V6 car you can use an oddessy 130a alt. You will need to lengthen the 4 wire plug about 6 inches though. Everything else bolts right up

 

Shoot, I forgot to include that it's a four cylinder. Thanks for the response.
