I found the radio is a weekness of the system. Going with an aftermarket radio would be a plus, but I havent personally seen a nice looking one. I kept the stock radio and added an EQ, amp and single 12 inch sub.punkman79 said:I like some deep bumping bass in my music. nothing to shake the whole neighborhood but enough to enjoy privately in your car. Did I make a mistake in getting the HK upgrade. Is the rattling true? I REALLY don't want to mess with my car using aftermarket parts. Any opinions???
