Review on 🎵 BOSS Audio Systems ASK904B.64 Marine Weatherproof Amplifier and Speaker Package - 500W Full Range Bluetooth Amplifier with Remote, 6.5 Inch 180W Marine Speakers, No Receiver Needed - Black by Chad Sorensen

Purchased to replace an existing radio on a pontoon boat. Was easy to install and the device works as expected. Has excellent sound quality. Connected to the Bluetooth on the iPhone without any problems. The only issue I had was the speaker wire that came with the kit. As I had an existing 4 speaker setup I used existing cable which was of a much better quality. I would advise you to buy a higher quality cable if you are doing a fresh install. An additional plug for connecting USB and 3.5 is a plus. Haven't tested 3.5 or other USB thumb links. Use USB to charge my phone.
