bring it on over i will hook ya up..
I'd like to know as well. In my Valkyrie's early life, I had an amp in a small trunk pack behind the passenger seat that I used to amp an iPod to a couple of blaupunk 4.5 " speakers in chrome housings attached to the bars behind a windshield. I can't recall make and model of amp but I do believe is was 75 X 4 W amp but I was only using 2. I thought for sure it was gonna sound better and louder than it did. I couldn't even hear it at 65 mph.
