Audio system had 2 Skar Audio VVX8D4 subs on an AudioQue 1200.1 amp until the Skar subs blew apart. I now a have an AudioQue HDC3 D2 10" sub to replace them. The car also has 2 runs of 0ga KCA KnuKnoceptz power wire. I also Added Infiniti Reference 6.5 Components to the front, and 5.25 Coaxials to the rear to replace the stock speakers. Before the Skars came apart it sounded awesome. Hopefully the 10 will be better. I wanted to keep the bass down with this vehicle since the truck is my stereo vehicle. Hopefully when I get back home from NYC, Miami, and Daytona I can order some summer rims and coilovers!
