I recently installed two 12 inch sub woofers in my contour. I half of the wires were already in the car when I got it I just had to run a power wire so I did that and hooked everything up. Got everything hooked up right and I got no bass out of it.

I pluged the rca's of a dvd player into the amp and put a cd in it and I got output from the subs. So I pluged my rca's from my headunit back in and I got no output again. I even tried using a set of rca cables from my old contour and they didn't work. Does anyone know whats wrong with my system? I'm running the following:

Headunit: Kenwood KDC-3011
Amp: Pioneer GM-5300T
Subs: 12inch Infinity's (I dont know the model right now but can get it later)
 
If your headunit is anything like mine, it had an on/off feature for the subwoofer preamp output, so i had to look through my manual a couple times and i finally found out how to activate them, then voila, bass. the dvd player was a good idea...at least you know they work. When i was up at late late at night finishing the wiring and it didnt work, i assumed it was my fault and re-wired everything, and tried a bunch of stuff i thought might be the problem. needless to say, i was pissed when i found out it was a friggin button.
 
My kenwood has you hold the down button on the FF/RW/Disc+/Disc- knob (the control knob) for 2 seconds and will either set the subs pre-out to on or off. Generally the treble/mid/bass setting will only set the "loudness" of the subs.

Try downloading the manual too. Might help.
 
Found the owners manual. Doesn't say anything about a button to turn on the preamp output.

However I was reading online on these headunits the rca jacks tend to die. So maybe that could be the problem?
 
Have you tried using any of the other RCA outputs on the HU, assuming it has more than 1.... Or maybe you have 2 pairs of bad RCA's and that's why your not getting signal.... Personally I never reuse other peoples installs... I always start fresh and do it with brand new wire that way I know they are good and not crap...
 
Amp powers on. The only thing weird I noticed about the wiring that was already in the car was the remote wire. It was a blue wire with another blue wire spliced into it. I accidently pulled the spliced in wire apart and my speakers went out. At this point I turned the volume up to about 26 and my subs were bumping. However when I sliced that wire back in I couldn't get my volume anywhere near 26 with out distortion. Ideas?

Click to expand...

Sounds like you disconnected the turn on for the factory amp.... and if you have to crank your system that loud to get the subs to work, you may want to turn the gain up on the sub amp so you don't distort your interior speakers...
