Count me as one of the ones that was originally skeptical.
After installing and getting some miles under my belt, I am more than happy with my purchase and would do it all over again. I don't know how you could expect them to sound much better. IMO, they really shine when you're riding. Sure, they get loud when you're parked, but I got the biggest smile when riding down the highway with my tunes bright and clear. I can turn the volume up ALL the way with no distortion. (It's also beautiful to be able to hear the stereo separation. With the stock speakers I might as well have been listening to AM radio...) After riding a few back roads with the volume at 50%, I was confident that I was contributing to early hearing loss. I also installed the flex-power antenna, and with that I feel I may have lost a bit of reception, but it might just be that I can HEAR all the crackling come through because the stereo gets so loud now.
Another note, the install was a snap. I think the most difficult part was messing with the bolts that hold the amp bracket in place...those are a pain to get to! The rest was really easy.
Last thing - big thanks to Dr. VTwin. Just got to get you guys on the east coast now to make things REALLY perfect!
