Over the long weekend I decided to swap out my factory head-unit in my 2000 Road Glide for something that actually had a CD, front panel AUX-in, and had an industry standard output resistance ie4OHMs. I put a JVC head unit in and matched that with some Polk db525 speakers. I can't tell you how much of a relief it is to have a little more of that proprietary HD crap off my bike. I now have the ability to add rear speakers if I want, without having to buy a "harness" or a "kit" or a whatever harley likes to bend us over for at the dealer. The second thing that surprised me is just how crappy the factory speakers were. I was always told that speakers should have magnets, you know, but screws wouldn't even stick to the factory units, what a waste. My system now sounds 10x better than before, and I can actually hear it on the highway without maxing the volume. I might be singing a different tune if I just dropped all that money on that fancy new radio for '06, but to get all the functionality of that new radio, it means spending hundreds/thousands of dollars on wiring harnesses and crap, gimmeafrigginbreak. Harley knows dick about sound systems, joining with H-K was a step in the right direction, but in usual HD fashion they still found a way to screw those keeping them in business. I say leave the bike building to Harley, but forget about HD sound systems. Sorry for the rant, back on topic. Hogtunes or otherwise, just get rid of that factory crap and you will be much happier.
