2009 GMC Sierra
Pioneer 3200 Deck with Steering Wheel Controls
Memphis Audio 500 watt Street Reference Mono Amp
12" JL Audio Subwoofer in an old body style GM sub box
Put the amp behind the seat (back carpet was already cut for an amp.....well, chewed up)
Bass Knob was put down low
Deck pushed the stock speakers better than the stock deck could
All in all....good sounding system
