I went by that T&A truck stop tonight down at I-70 & ward road, they have several remote speakers there (Autozone, O'Riley, Radio Shack, and Napa do not). Got the remote speaker installed, and the sound is much improved over the tiny speaker under the passenger seat. It's neat how wide this thing is.. I can stick a speaker there and the brake, seat belt, arm rest, all function just fine still, I could even put another on the other side if I wanted. This is good for now...
