I pulled the stereo system I had put in my daily driver car years ago when I thought I was going to sell it. Decided to not sell it, been driving the car for 5 years with no audio of any kind in it, anything would be an improvement.
(I still have all the speakers, head unit, amps and wiring sitting in a box in my basement somewhere. Just didn't care enough to put it back in, still don't) The sound of those 6 throttles popping open is music enough for me! (I ride one of my motorcycles nearly 300 days a year anyways)
