I posted this on the HD Forum about upgrading the '05:
This is what I have ordered so far:
HK head unit, previously serviced Iron Cross
Non-ultra overlay harness
Lower fairing speaker boxes, grills and hardware
Lower fairing speaker connectors
4 Polk MM651 6.5" speakers
Adapter rings for the upper fairing
Acoustic inner fairing speaker pads
Arc Audio KS 125.4 amp
Arc Audio XXD 4980 amp
2 Arc audio amp harnesses for Harley
Hogtunes dash trim tweeter speakers
Boom Audio saddlebag speaker system
Primed saddlebag lids
I'm thinking I might need to get the rear speaker switch, but I'm not sure if it's a requirement or a luxury. What problems could I expect? I know about trimming the speedo and tach housing 1/2" if I use the 125.4 in the fairing. Anything I'm overlooking?
