yes please, if you don't mind... ive installed many amps, but they were always in older cars that I took the oem head unit out and replaced with aftermarket head unit that has rca outs. and other than my friends caddy (which , unless you wanted to lose your dome lights, cruise control, wipers, and some other stuff, you had to keep the oem unit wired up in the trunk while splicing in the new unit up front) installation is really straight forward. Ive never tried to run anything to a oem stereo without rca outs, so everything you described up top might as well be Spanish to me
