Wow that was easy. I done a lot of searching on this as well and went crazy on all the info.
I just settled on the plug and play systems out there for a one time shot at this. I know there is louder and better but I'm some what pleased with my purchase, if not for the ProPipe it would be a little better at 70 mph.
My truck and boat are outfitted with all JL Audio except for head units, bikes are a little more difficult to get dialed in to a personal liking I think.
Take the good advice they have given, Good Luck and welcome aboard.
