        Rated 1 out of 5 by from Not impressed Spent thousands putting this along with the boom saddlebag lids on my 15 SGS and was left dissapointed. After several long trips and struggling to hear the speakers at 80mph interstate speeds, I turned to a stereo shop. I had the shop remove all the boom junk and install an arc audio amp and Hertz hi energy speakers. Have no issues hearing system now on windy days even. Spent less on the stereo shop setup including install and am very satisfied. Don't waste your money on this setup!!

        Rated 1 out of 5 by from Not Work the Investment Replaced front speakers in 2015 Street Glide and was not worth $1000 (w/installation). Did not improve the volume or riding experience. The instore demo raised my expectations and does not give a true depiction of the sound on the motorcycle, even when parked without the engine running. PLEASE DO NOT BE FOOLED!

        Rated 2 out of 5 by from Store display misleading Store demo display would lead you to believe there is a huge improvement over the stock system, but not so much. It seems those having the greatest success are those adding the bag speakers in addition. With the outrageous cost it simply doesn't make sense to even try this upgrade without adding speakers to the bags and if you factor in the high output charging you've invested a lot of cash for minimal results. I mean face it; how much better can the sound be going down the road on a motorcycle??? It simply isn't cost effective. FAR too much money for a mediocre result.

        Rated 3 out of 5 by from Take a pass on this upgrade. Had this system installed just yesterday, and am very disappointed in its performance. Marginal (at best) improvement over stock output. I expected it to deliver a much increased volume at a lower level on the indicator, but in order to get anything at all from the amp, you have to crank it to max volume. The speakers are decent, and to be honest i don't expect huge sound from fairing mounted units. But the output of the entire package is severely lacking, and i would definitely recommend avoiding spending money on this product.

        Asked by: mila
        Hello Mila, When you install this kit, there needs to be a software update as well by the dealer. I would suggest taking it back to the dealer for an evaluation as to what may be causing the problem you are experiencing. Thank You!
