Just installed and road tested the system, everything works great and sounds great!   I personally could not install the amp under my seat as the shock absorber takes up all the room, I therefore installed the amp in the tool box on the left side of the bike and ran all the wires under the tank for a nice clean looking install!  Everything was pretty straight forward for install, took about an hour to do!  I have a 2003 V-star 650 with DG Hard Chrome pipes which are VERY loud and even with a helmet on at 70mph I could hear the music just fine and it still sounded great!  I installed a 150 watt amp with the 4 inch Blaupunkt speakers, and Im using a 4gig Ipod Mp3 player!  I couldn't be happier with the system keep up the good work and keep offering quality products!
