My husband put this on one of the farm Polaris CUV’s since installation is beyond what I would able to do. He was able to install it on a ranger using the roof system as the mounting position for the speakers. It installed easily enough – basically clamp the speaker to the roof support bars, make sure to use the included rubber strips to get these to clamp securely or you will be remounting these with the rubber strips again once they slide down. Wiring was simple as it all goes to one plug that attaches to the amp. This does mean you will be mounting all 4 speakers. And since the wiring is together in a harness, some thought is required as to where you put the speakers and a good route to where you want the amp installed. The amp install is simple as it basically needs power (12vdc) and not a lot else. It does come with a handy audio input jack so you can use something like an old iPod for audio input. It also has BNC inputs if you have say a radio that you would want to connect to it so there is some flexibility there. The Bluetooth hook up was simple and works well, but again do not hide the amp behind a lot of metal or this may not work to well.
As far as fit and finish, the only thing I can knock this on is the quality of the clamping hardware finish, but being on a rough duty vehicle this is actually okay.
The bottom line is: Overall installation is simple, and the unit is easy to use.
