So installed an amp and 2 4 inch speakers last winter but the amp i had over heated and was junk. So this winter im taking my pioneer radio and those 2 speakers and adding in 2 more tweeters next to the gauges. Installing a miniature antenna behind the gauges under the windscreen and the radio is being mounted on top of the tank. I plan to use sheet metal and bondoing it to make it smooth and clean and then having it painted. So if I am lucky it will look so sweet and custom that I will be very happy with the end result. And before anyone says it wont be loud enough to hear on the highway I already wired and tested it yesterday to make sure it is do able.
