so I have an idea for putting some tunes on the bike. here's my thought... get an amp (not sure where to mount it yet), and hook it up to a 5 inch speaker (obviously marine grade). where would the speaker go you ask? I want to put it where the speedometer is. the issue now is finding a speedo I like to mount on the bar, figuring out all the wires to hook up the speedo/indicators. I also need to find an amp/speaker combination that isn't going to break the bank, but will be loud as hell (that's why im thinking going to a 5" may work). right now im running shark (junk) 650 watt system with 2 3" speakers (also junk). I can hear it pretty well going down the road, but it distorts. any opinions/advice is welcome.
