Image dynamics HLCD's, Focal neodymium mid-bass drivers in custom door pods. Alpine 5x amp and Audio Control 1/3rd octave EQ. Sub is Polk Audio C4, which is amazing in the G-body, as it can be a difficult car to add bass to.
Beautiful work. I'm in the process of putting something together in my GN that I've had for about 25 years. It does have some pieces that I'd like to keep such as the CDA-7949, PXA-h400, and the Rockford amps, but I'm open to suggestions on speakers. Also trying to incorporate bluetooth streaming somehow.
