Polk Audio MM 522
I installed these in the fairing of my 2016 Victory Cross Country. They are being driven by a bridged KenwoodKAC-M182BT Amplifier that puts out 90W RMS per channel (200W peak each channel / 400W total). This is just beyond what these speakers are rated for but they still work pretty well. There is some distortion when turned all the way up like you would expect. They are not very responsive for the lower frequencies, but they are only a 5.25" speaker.
