After reading the responses and also seeing a slight trend with the setup from what others have said maybe I should try something new or maybe I just had bad luck. Do I swap out the amp or the speakers? The amp would be easiest to do obviously. Who runs 4 Polk MM651's and what amp do you use if you've had good luck. I will say that I purchased my speakers from Sonic Electronix and they were effortless to deal with and they've already shipped out a new pair, great service.
been running MM651s for over 2 years (same 2 pair) and on the SS 520D for quite sometime (at least 6 or 8 months) now and nary an issue. Also running a set of Pioneer TS-D6902R 6x9s in the lids with a SS 350D
The system on my 2006 Road Glide is: HU=Sony MEX-BT4100P, Amp=RF PBR300x2, 2 fairing speakers=Polk MM651. The crossover switch was set to AP. The gain was set to 7. I seem to have blown the right speaker. I seem to be getting faint tweeter sound out of the speaker. The tweeter post is straight. I swapped connections and isolated the problem to the speaker. The woofer cone seems to be separated from the circuitry. When I gently depress the woofer cone toward the back of the speaker, something makes contact and the speaker seems to be playing at a normal level. When I release the cone, back to low level high frequency. Interesting theory on a bad run of speakers unless we are all setting them up wrong. Hopefully sonicelectronix will be responsive when I contact them tomorrow.
