Just tried this new system ...simple install, no amp to bury just three wires, and simple mount on bike....sound is good, better behind my windshield of course, and has Bluetoth, an SD card for direct play, and FM radio.....Overall nice unit and reasonable price for what I got...will continue to try and post more pics....saw video on youtube and then looked up under Firehouse Technology on facebook. Bought off ebay under the same company name...79-89 bucks Let me know what you think....love to be able to listen to my spotify channel when riding!
