I just did a stereo upgrade on friends Roadglide Ultra.
We decided not to go the usual bolt-in kit from Hawg Wired, Biketronics or JM.
He had a hog Tunes system with a instrument tweeter pod setup that had seen it's better days
We decided to go with the HAT (Hybrid Audio Technologies) Unity Series 6.5" Component speakers. I put the 6.5" mid bass's in the faring, mounted the HAT tweeters in the Hog Tunes tweeter pod and drove these with the Hawg-Wired RS-400 400 Watts RMS Amp
In the faring lowers I installed a set of Hogworkz 6.5 Inch Harley Lower Fairing Speaker Pod Mounts and mounted a set of kicker 6 3/4" CompRT Dual Voice Coil Sub Bass speakers and also drove these with another of the the Hawg-Wired RS-400 400 Watts RMS Amps
I was pleasantly surprised at how well these small subs performed with such a small enclosure.
This is a "Great" sounding system.
Incredible highs and mids from the faring that you can hear clearly at 100 MPH
The subs in the lowers are really for Bike night and around town cruising, anything above 60-70 MPH and you cannot hear them, but he sure sounds baddass pulling into the bar on Bike night.
