Cool that we're seeing some approaches in this thread!
I'm still waiting on my retrofitted radio, but I've received the speakers. Got a killer 40% off boxing day sale:
Hertz 300 Watt 2 Ohms D Class Mono Car Amplifier (DPOWER1)
Hertz Cento 4" Two-Way 40 Watts RMS 4 Ohms Coaxial Speakers - Pair (CX1005)
Hertz Cento 5" Two-Way 50 Watts RMS 4 Ohms Coaxial Speakers - Pair (CX130)
Hertz Cento CS 250 S4 10" 300 watts at 4 Ohms Subwoofer (CS250S4)
The 4" speakers will go under the dash in the original speaker location, the 5" speakers under the seat facing forward, and the sub under the seat facing up. The subwoofer amp will be behind the seat where the gas tank was, along with some other electrical outposts.
