Pros: These look and sound great. The bluetooth worked well. I was using an android phone and had no problems. They are built solid. They were plenty loud while cruising and great for just hanging around having a cold beverage.
Cons: My only real complaint was maybe the bass. While the bass is smooth at lower volumes it tails off at higher volume. I am a bit of bass head, so I'm not sure any speaker really has enough bass. The mounting options may be limited for some. The unit I used was mounted with a custom bracket. It may only come with a mounting strap for a roll bar application.

Boss Audio Systems

It’s not a a speaker made for your boat, but it would work. This bad boy is made for your outdoor adventures! Hunting, camping, cruises on the side by side whatever you ride this speaker set may be just what your looking for. It’s available with or without bluetooth. I personally have tried the bluetooth version and it worked as advertised. I was not involved in installing this speakers just the listening and streaming of my favourite music.  I have tried and or listened to a lot of different speakers and these stack up with some of the best of them. They look aggressive and appear built to last. The bluetooth worked great auto connecting when we returned to the side by side.

Bluetooth Audio Streaming

Bluetooth technology is a short-range radio technology that was developed to provide wireless audio and data transmission. Two Bluetooth-enabled devices (like a mobile phone and a car) can be paired so that they establish a communication link when they come within range of each other. Depending on the device, the range can be anywhere from three to 300 feet. The ATV25B supports A2DP (Advanced Audio Distribution Profile). A2DP is a Bluetooth profile that allows for the wireless transmission of stereo audio from an A2DP source (typically a phone or computer) to an A2DP receiver (a set of Bluetooth headphones or stereo system).

Compatible With Audio Output Of iPod / iPhone, Smartphones, And MP3 Players

The Aux-in is another great feature of this product. You can connect a device that has an Auxiliary output (such as your iPhone/iPod, smartphone, and MP3 player) straight into the Auxiliary input of your ATV25B – basically a cable that has two 3.5mm audio (male) connections.

It can be hard like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber, or sticky like glue.
