Ok ill definitely check the grounds. I know its not the wires, ive had this setup for over a year and have had it loud as all hell and it hasn't ever been a problem. I am running wire thicker than a pen I think around 4 gague or something of that sort. I have 0 gague from the battery to the capacitor so im fine in that sort. The ground for the wire is under the seat. Scraped the paint off and just screwed it in. I am thinking a ground wire could be loose because it only happens sometimes. Also it will happen after I stop hard or something like that so im gonna guess a loose connection. Its a sony xplode amp, it wasn't very expensive so I figured the subs might have rattled the electronics in the amp out but it still works. I will check the grounds. BTW yes I do have a cingular phone but ive never had problems with the interference on my stereo, I have on the computer speakers tho. Thanks guys appreciate it!
