Premium Sound perplexion, not repeated Options

[jbcustom]

I am completely bewildered. My celi has the 8 speaker, premium sound option, I was trying to replace my stereo last weekend, and pulling my dash apart I noticed that I had the factory amp, explained in the how-to article. I had a secondry amp under my drivers seat. Heres the juicy part, the wire harness going into my factory radio does not match the 1987+ harness. Instead of being two plugs into the radio it only has one! WTF? I have decided to team up with a buddy of mine to relocate the battery, put my new headunit inside the passenger airbag cover (my car was salvaged so the airbags dont work), we're planing on putting small actuators that with a switch will lift the panel exposing the unit, for heat a small 80mm pc fan inside to cool the unit. What do you guys think? And does anyone else have that single plug?

Addressing the radio harness question, I'm not sure how the premium sound system wiring works but on the standard stereo with one amp, there is a connector from the factory stereo to the factory amp and then a connector from the factory amp to the factory wiring harness. The factory wiring harness DOES have 2 plugs but you have to find this connection AFTER the factory amp. You need to remove these amps from the equation if you are using ANY kind of amplification - be it from the head unit or an external amp.
