This GMC Sierra came in for a lighting upgrade, along w/ a JL Audio Bass upgrade! We installed ODX projector series LED lights for the Hi/Lo's and ODX Halogen series LEDs for the fogs. We then built a custom sub enclosure to hold a single JL Audio 12TW3 sub, powered off our client's own 500/1 Slash amp! This truck now sounds as good as it looks, and can light up any road!
