I've got my 12 and I'm sure this had been talked about time and time again. It's January as we all know and while I have the bike off the road, I want to do upgrades to the speakers and add an amp. With all the knowledge here, can anyone recommend a great set up that's worth opening my wallet for? Currently running the stock set up, which I can still hear while doing 90+ but I had to turn the bass down and it's not a pleasant sound.
