I have a Pioneer DEH-6 stereo. Recently, my amplifier seemed to loss bass so I sent it off to be fixed (it is under warranty). After diconnecting it and sending it off, I discovered my stereo wasn't putting out any bass at all. I checked all wiring, and everything is fine. I recently discovered that if I set my balance all the way left or right, the bass kicks in, but otherwise it is non-existent. My balance range is 0-9. If I set it to R9 or L9, the bass works, but it gets lower the closer I get to 0. At 0, it goes out completely. I hooked up another amp I got from a friend, and it wasn't putting out much bass. If I set the stereo to L9 or R9, it booms. I also tried replacing the fuse and that didn't help. Can anybody help me with this? Does anybody know?

EDIT
The amplifier and subs aren't the problem. It's the head unit. I will try reversing the polarity of the wiring on the actual car speakers to see what happens. Thanks for your answers!!!

Ok, I checked the polarity of the wiring on every speaker, it it it still not working. My set up is the Pioneer DEH-6 with two 6&1/2" speakers in the front and two 6x9's in the back. I have two Audiobahn 10" subwoofers and a Profile 2000w amplifier. I disconeccted the amp yet again, and the stereo itself is not putting out any bass. The polarity is right on every speaker, and yet it only puts out bass if the stereo is set to L9 or R9 (it works either way). I am wondering if there is something wrong with the head unit itself. Push come to shove, I can buy a new one, but if I can save 100+ dollars and fix the one I have, why not?

Acoustics is your answer, its called cancellation or out of phase. If i understand it correctly, you are powering just two front speakers right? if so, disconnect one speaker (either left or right) from the Pioneer head unit, then reverse the wiring of that speaker and it should improve bass. Tip: disregard the polarity wiring wether its reversed or not, if you got the bass back then thats a properly wired speaker for your situation. in short both speakers are in-phase with each other working together to pound your skull in, lol.

Your speaker are out of polarity. Check and make sure that the + red terminals and the - black terminals on both the speakers and the amplifier are matched up. This does make a difference. If it is wired correctly and still does this reverse the wiring on one of the speakers. This should fix the problem. Good Luck!
Are you running your subs with the line level (RCA) or speaker level inputs?

It really just sounds like some messed up wiring. Check all of the amplifier connections and the RCA's in the head unit.
EDIT
Yes - the speakers could definitely be out of polarity. try switching the positive and negative on one of the subwoofers.

I see all the information that you add and edit and i have still say the same like the other people i am almost 100%

Your Speakers are out of Phase!!
Check the Wires. You should have Equal Length of each left & Right Wires. Difference in Length can cause this Problem.
Also, make sure that the Positive & negative Wires are Correctly Connected!! This is IMPORTANT!! Make sure that they are not Crossed.

reverse the polarity, by simply swapping the positive and negative of either speaker.

your speakers are out of phase
possitive negative wires are wrong
check them and you will see
good luck
