Why aren't my front speakers working!!?? Help Please!!!

I recently bought an old corvette, decided to leave the dashboard unmolested and go with a stand alone system in the rear compartment, and throw in some extra speakers up front. I'll try to over-explain, hopefully someone can figure out what I'm doing wrong. I had my uncle install the stand alone section (Wiring the amp to the battery, remote lead in to the CD player ect..) and figured I'd be able to handle the two front speakers. Guess I was wrong! So the 6X9's, amp, and CD player all work fine, just can't get the fronts to work.

Here is the rear stand-alone section. 2 6X9's, 4 channel amp, and a Sony CD Player.

Wiring to the amp (12 gauge wire, the top are the front speakers, the bottom are the rear)

Left and right audio cable at amp.

So my that was the visual of my though process, wire the speakers (+ to +, - to -), connect the L and R audio wire, turn it on and shazam it would work. But no


Did I miss something here? What the hell am I doing wrong??
Any help would be greatly appreciated.
