Boom! Cruiser Amp & Speaker Kit is rated 2.8 out of 5 by 9.
Rated 1 out of 5 by from Doesn't even deserve one star!!! This is the second unit I have purchased over the last 4 years .the first just like the second the left channel went out so was only playing on one speaker. They replaced the other at no cost to me. Worked great and than sold that bike. Bought a new RK and had the Boom Audio put on it and the same thing happened. Left channel went out at first now doesn't play at all unit is less than a year old but this time they are only covering parts . Over the last 10 years I have spent $1000s with Harley and bleed black and Orange but with bad service at different locations in Northern Michigan and now this I may be looking at jumping ship and looking at buying a different brand. DONT WASTE YOUR MONEY!!!!!!!!

Rated 3 out of 5 by from Descent stereo I installed this stereo on my 2008 Road King. it works pretty well, you'll start losing the sound at upper highway speeds but that' to be expected. But around town and back roads works well. My only complaint is the chrome started flaking off the speaker trim rings in less than a year. Now they look like s---t. You can buy a new pair for $40 buck but why bother. should be warranteed. Get the black ones,may last longer.

Rated 1 out of 5 by from Don't waste your time these. Been wanting a set of speakers for a while now. So I went down to the Harley shop to check them out. Sound awesome in the store. Sound great at the stop lights. But once you get on the road and get over 60 mph. You might as well shut them off. All you hear is, well pretty much nothing. I even turned the base down, and still couldn't get good sound. If you're going on long rides or cruising down the interstate. Get a set of headphones. Would not recommend for the money. Pure junk!

Rated 4 out of 5 by from Good Speakers But Pricey dealer installed on a 2015 fat boy lo. these speakers look cool, sound good, and do pretty well even on the interstate. i use with a dedicated iPod nano which also has an fm radio. frequent volume adjustment is needed at stop lights/lower speeds. i suggest also adding a fat boy windshield bag to store your phone/iPod and a handlebar mount auxiliary port to keep these accessories charged on longer rides. with parts price and three hours HD labor to install, the the total price is fairly outrageous...
