I am looking for the color codes for the factory monsoon amp in my 04 grand am. Which wires are used for a signal converter to power an aftermarket Powered sub without disabling the factory system?

Can you help?

Hey, Thanks! That worked out great, sort of. Now I have a new problem. I installed a powered sub and wired the low level inputs in ahead of the monsoon amp and all is well. Until I start the car and then the sub shuts down. If I unplug one channel, it will work but will not work with both channels connected when the car is running.It will work for hours with the ignition in the accessory position but when you start the car, the sub shuts down after just a few minutes. If you shut off the car, (just back to the acc position, the sub will pick back up and go again. I have checked everything from polarity on the inputs, to the charging system (thinking it was handling something) to grounds and power cables.

Do you have any helpful hints? Is there something in the security sytem in 04 that affects the radio signal output when the car is started?

yea as dumb as it sounds this is how it works the amp is actually sound sensing so heres what i did take the neg off the left and pos off the right this has to be used for both inputs to the converter rca out from the converter will use a y adapter to regain 2 rca's it worked on mine
