Guess I'm old school. I still have 2 Soundstream SPL Mules that I took out of my '94 K3500. Those will be going in my '01 toy. Very good quality and sound.

Wow that sucks for mileage! I used a LMM 2007.5 for two weeks, ccsb, completely stock on winter fuel and was getting 15.5-16mpg. There must be something wrong somewhere.
