help with stereo

[parker]

I'm having a problem with my stereo. recently, i installed a new system. now, i am having problems with the bass hitting even when the volume is turned all the way down. it bumps repeatedly, and doesn't quit. i've had to turn the gain almost all the way down, just to hear the stereo, otherwise the incessant bumping takes over. I have a sony xm-2165gtx xplod amp (says 1000w, 2-ohm capable), 2 12" JL W1v2.8 subs (8 ohm), and a Pioneer DEH-7700MP head unit. i've got it bridged, because one channel doesn't work on the amp. i've checked the ground, fuses, rca, and remote wires. they're all fine, and this isn't the first time i've had a stereo hooked up in this car. the only thing that was different about my old system (which worked perfectly) was that i had two 12" JL w0s. i don't think car noises are interferring because i didn't have that problem before. i don't think my amp is bad because it worked fine with my old system (aside from it getting hot, but who can help that). does anyone have any idea what is going on with my system?

Ding ding.

Get it fixed or get another amp...you can't do what you're trying to do.

why did it work on the w0s, it was bridged too?

Who knows.

But "bridging" usually requires that you have two working channels //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

maybe i'm saying it wrong. i've got the positives going to one side, and the negatives going to the other. would wiring my current system in a series (the circle: negatives to one side, positives to other, a wire going (+) to (-) in-between) help?

Okay

I would suggest you've located the problem.

Umm...see above? Or, see below...

Keeeee-RECT!

If you only have one operation channel of output then your amp isn't bridged, fella. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif Sorry. Nor will it ever be in its current state.

ok, so i'm an idiot and don't know what my wiring is called. apparently, it's not bridged. whatever it is, it's working...somewhat. i've got both the negatives going to one side, and both the positives going to other. this is the same way i had it before, and it worked perfectly. excuse me for not knowing the terms, maybe i've got it wired 'parallel'. i don't know. but, i asked a friend, and he said to wire it in a 'series' (i think), which he explained as a circle, and something about impedance... at any rate, is wiring it in a circle something i should try?
