OK.. I've read through several of the threads, and at the risk of being tongue lashed for putting up a similar thread, I need to ask this question because I'm still on the fence on this. My 2011 XC has the Kicker upgraded speakers..it doesn't have an amp. I want better sound so the amp is going to be my next step. Most of the threads I see that provide comparison between speakers are after the bike received upgraded speakers with and an amp. Question is, has anyone compared the kicker upgrade with an amp to aftermarket speakers with an amp? If so, is the sound quality of other aftermarket speakers that much better over the Kicker upgrades?
