After both pairs of my Polk MM521 speakers went out, I had to go into the fairing again. I am sending the Polk back after only have them in for a weekend. WTF. Well, I bought the Alpine SPR50 for the rear and Fusion Electronics MS-FR6021 Marine 2-Way Full Range Speakers, 200W, Pair $116. These are highly rated.
While the fairing is off, I rerouted the wiring around. I was only being able to 2.5 FM channels out of 11 in my preset. After I rerouted all the speaker wires, power wires that are everywhere, taping up the speaker wire extensions, I was able to get 6.5 channels. So this tells me that its the radio with a weak signal. I think the radios are the trouble. I bought the extended warranty on my bike so I know winter time the radio is going in.
