96 Supercab..Prem Sound, Amp Location??

[96er]

Hey everyone....I have tried to install an new Stereo in the truck...everything works, but no sound..then after reading some of these forums, Im guessing that I have an External Amp somewhere. Not behind the passenger kick, I looked..only the Air Bag control mod. This is a Super cab....any ideas? and also how to bypass it. Thanx
