In an attempt to hook up another amp to run my high’s and mid’s I have encountered a problem. I spliced into the two front speaker wires coming out of the PAC (OS2). Now my Front Right works fine however my Front Left emits a cracking sound (only comes from the negative wire.) I have checked and the speaker is not blown.
The wires I connected are properly matched up. So then I disconnected everything and hooked it up to how it was before I spliced. The cracking sound is still there.
So now I ran a jumper wire from where I spliced on the Left Front Negative (output of the PAC OS2) to the Left Front Negative output of my Head Unit (bypassing the PAC OS2) and the cracking sound stopped.
Now for the fun part – the volume was very loud – way louder than the right side. I could not turn the volume up a quarter of the way because it was way too loud. I removed the jumper wire and hooked everything back up to spec and the cracking is still there?
What is the cause/origin of this problem?
How would I go about fixing it?
I appreciate any help/comments/advice given.
Thanks!
I have a 2007 Silverado Classic with Bose factory speaker system except for a XOVISION Double DIN (PAC OS2 Module Connected) and Fosgate P6002 Amp running two Fosgate P3’s.

The OS-2 module seems limited to 06 models. If the 2007 model is pretty much the same animal, you'll be OK. If they made some major soft/firm ware changes in the data line cables and package integration needs, this may account for your troubles?
I would have a Pro Installer double check this work. (A senior tech or shop manager if possible)

PS Note the warnings about the PCM and BCM modules when using this product. The modules are the main brains in GM vehicles and if they start throwing codes, you'll have a rough time and much expense to get them figured out.
