Wanting to upgrade to better sound. Currently have speakers in the firing and touring package. Wanting to add 8" saddle speakers, different fairing speakers and larger amp. Don't know if I want 8" speakers with a separate tweeter or just a 8" speaker in the lids. I don't want to minimize trunk or saddle bag space but looking for an amp that goes in the fairing. One place recommended Rockford fosgate. What's your input and what have you done.
