Speaker Upgrade
I found the factory harness for the door speakers, but not for the sail... i even went to shoving my arm all the way down in there and couldnt find the bloody harness, where should be my next step to look, it does have the monsoon amp. I can't even find a trace of a wire

"Firebird coupes have component 6.5S (6.5" oversize) 2-ohm mids and .75" 4-ohm tweeters mounted separately in the doors, dual voice coil 6.5S (4-ohm + 4-ohm) subs mounted in the sail panels (beside the rear seat), and component 4" 4-ohm mids and .75" 4-ohm tweeters mounted separately in the hatch area. The two door mids and two hatch mids account for four of the eight channels of the amp while the DVC subs account for two channels each to make up the other four channels. This leaves the front and rear tweeters to be powered directly by the head unit."
To drive a sail panel SVC midbass cone in a Firebird with the Monsoon amp, you just resign yourself to giving up one of the available amp channels.
