Check out this alternative..I installed it today in my 08 Street Glide. Kenwood KFC-X1300 - 5.25 Speakers - specs are 40hz to 25,000hz - excellent range. Bought for $50 at salectronics. Went to Lowes and got big roll of Peel and Seal in building materials for $15 - enough to do like 3 complete fairings.
I Insulated the whole inside of Batwing. Stock speaker rings had to be trimmed slightly for Kenwoods. The Kenwoods have a plastic deal that holds tweeters. mount this on the thin (bottom part) of factory speaker rings.
Tweeters swivel and can be adjusted.
It sounds insane - way better than stock- super clear and great mid-bass.
Well worth the $65 bucks!
