  • wow, what a great amp. recently installed it in my boat with a set of new speakers, and it sounded way way better. definitely rocks and its value is off the charts for the price i paid. pushing my 6x9s to their limit with great sound quality. easy to set up. can't go wrong with this amp.

  • Its components and design seem to withstand any issues with getting exposed to water. It has that durable vibe but will still check it out more and will give a another review next month. But it looks great and it sound even better too. Seems like I’m going to have a fun boat ride with this amp.

  • Bought two of these and had them installed in my boat, running all of the eight speakers and there is really an improvement on the sound. The amps feel to be durable and I hope they have the longevity that I expected from them, as the amps before them just gave up on me in less than two years.

  • Powering the 6.5 speakers of my boat and its doing alright. Good power output. High quality sound with great clarity coming from the amp. Does not disappoint, especially for its price. Great value for a marine amplifier.
