Review on 🔊 Enhanced Power Acoustik MSA4-1300D Marine Grade 4-Channel Amplifier for Superior Performance by Andrew Dickens

I've used them on three boats and they seem to be holding up well. One setup was on a Bossman boat, it was exposed to a lot of saltwater moisture and works great with a JL Audio 7. I have two of these units for my main JL 6.5s and another for a JL Audio subwoofer. I had to give one star because the amp sounds great to most people but doesn't have the clarity of more expensive amps. It's also not the same price range. If you're looking for a great sounding amp that's power efficient and holds the sound well, look no further than these amps. If you're looking for superior quality, pay at least five times as much.
