This amp is amazing! I put a picture of a DS18 speaker enclosure I bought for my jet ski as it is relevant. I wanted to add a sound system to my ski and they offer an amazing speaker enclosure, the only one I could find for a jetski actually! So I saw this waterproof amp and purchased it. Be warned it puts out the sound and clear sound with great heights and lows. Just make sure you get speakers that can handle the power or don't over set the sensitivity because this amp is a beast! (in the best way). It is compact and easy to install. I could not be happier with this amp and DS18 products in general! Highly recommend! I don't usually write reviews but this is worth it!

I like that this amp is waterproof and compact size, but even with gains turned all the way down I get interference/whine/signal noise coming out of the speakers on my Waverunner. I had a similar Kenwood amp before this one and it picked up NO other outside noises like this cheap amp. I even took it to a shop to check all connections and grounds. Never again. You get what you pay for.
