I just finished installing my sound system in my 84 C4. the factory bose system was there. i installed a sony radio, speakers 6 1/2 front and rear 6x9 with a 12" sub and a bazooka AMP. I use the bose wiring, you just have to figured out which wire goes to the speakers and not the bose speaker amps. for the AMP i use the driver seat frame bolt for ground, it work (no annoying noise background noise)

IT SOUND REALLY GOOD..i only spend $500 on crutch-field.com. it came with everything that i need to installed myself. :burnout::burnout:

looks good man. Nice work!!
