installed BT471 amp with the 6 1/2 speakers on a '05 electraglide standard that already had a dealer installed system. installation was a breeze (after i figured out what Arbitary meant LOL). much clearer and has the same volume output at less than half that the stock system had @ full volume. thanx for agreat product.

I installed the 75 watt amp and the 6.5 speakers on my 1998 FLTC, leaving the stock radio in and the sound is awesome. Next I'm going to put a sound mat in the fairing and rear speakers.
