Thread: 06' GXP Sound System Help

Everything comes from the stereo (LF,RF,RR, RL) in low level and goes to the amp, the amp then takes this and sends the bass and the highs to the proper speakers.
Im not sure of a way to get around this, but im thinking maybe specialized places like stereo shops may have an adapter to combine the two out puts from the amp into one...I will look on monday for some diagrams and info on the operation of this system so you can get an idea of how it works and such.

Had a very similar problem with a lack of bass, with the stock monsoon head unit. After days of searching finally called a dealer and got a wiring diagram for the plugs into the amp. I have an 04 Grand Prix GT, not 100% sure the amp is the same, but it most likely is, maybe this will help

Michael, it's been a while but... I'm up against it too. Did you uncover any way around the 4-wire (mid and bass) outputs from the monsoon amp to an aftermarket, 2-wire speaker without hacking up the speaker?
