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?

I believe all factory-amp cars have that single plug.

As far as putting the head unit under the passenger airbag cover, I wouldn't do it. You won't be able to change CDs when driving or look at the screen or make adjustments very easily. Plus you'd have a large blank opening(or a non-working factory head unit) where the factory head unit goes. The only advantage that I could think of would be that the head unit would be well hidden so thieves wouldn't know it's there. But it seems like it'd be a huge hassle(both the install and everyday use.)
