FEATURED REVIEW12/3/2023It is not a stand-alone unit!I thought that it is a stand-alone, complete audio kit since it says in the box that it includes the Amplifier, bass twitter and other accessories necessary for it to work. The worst part is i cant find the kit with an amp that is needed for it to work. It says, product UNAVAILABLE. Now im stuck with these unusable speakers 😫 read more.

FEATURED REVIEW12/30/2018It’s okay, if a little expensive[This review was collected as part of a promotion.] For those of you that claim you can’t hear them above 60 mph, I would suggest moving in behind your windshield. Secondly, I have no problem hearing mine all the way into 75 mph or so. You might also try a full face helmet that cuts the wind noise down. read more.
