I just upgraded all the highs and added a sub to my 8th gen coupe. I will post pics tonight. I am now running Infinity Kappa Perfect 6.5" 6.1 components up front with 1/2" spacers in the doors, Rockford Fosgate T162s 6.5's in the rear with the crutchfield speaker wiring harnesses, (1) 10" Rockford Fosgate T2D4 10" in a 2.4 cu ft ported enclosure with a Power Acoustik OV1-4000 mono amp pushing it, and a Rockford Fosgate P4004 4 channel for all the highs. I have Knukoncepts 0ga wiring, split into dual 4ga. Factory headunit, no battery upgrade as of yet, will get a yellow top in the future. It sounds amazing, and surprisingly does not seem to strain the electrical system that much. I am overall very pleased! PICS TONIGHT!:thmsup:
