Pyle Hydra Marine 400W 4-Channel Amplifier - Waterproof with Dual MOSFET Power Supply - GAIN level Controls - RCA Input - LED Indicator - Compact Design for Boat/Vehicle Audio - PLMRA402

Best little amp for sale on Amazon and it works great.

This amp works great. Makes my cheap radio sound like a high quality unit.

Let me start with im not an audio person- i just want something that sounds decent.If your looking for sound only with no quality, bass or volume this will be fine for youThe small bluetooth speaker on my bench has better quality, clarity and bass then this outputs.Increase the volume and it lost everything, increase bass level sounds terrible, overall a disappointing experience and there is no way this is 400w outputIn the end do your self the favor, save the time and spend a little more for something that's built much better.

Strung little amp it works great in my boat I used it with 4 6 1/2 speaker and it sounds great

I’ve had this amplifier for a good couple of months now it hasn’t given me any problems. I’ve blew a couple of fuses in my car but that thing never gave up. I’m running 12 gauge wiring same as the speaker wire and power wire ground wire ACC wire and it’s still output wires don’t get hot. It also doesn’t get hot. I wouldn’t recommend for a boat as it is cheap but for the money, the audio quality is great and as long as you keep it in a car, it will do just fine. I have three amplifiers and I can’t tell you how much work I’ve put into my car if you’re looking for something simple to use that’s not complicated do this amp you can run it off the original head unit wire

This amp is small enough to fit in tight spots and works fine. What else can you buy in this price range? Works as it should!

None of the cheap car audio amps were below 70$. Low and behold this little guy just popped out of no where. In the 20$ range... huh? Yea i thought so too. Got it, installed, set crossovers to my speakers ranges. Sounds bichin'.Other reviews say its not 400 watts... maybe? But i couldnt get my stereo to 27 of 65 w/out clipping. Just terrible. With the amps gains set to jist the 1st notch - Im able to get to 57 w/out clipping, and thats way loud. Just need some tweets now. Great product I believe (havent had more than a few days, time will tell) - but great product thus far. Cheap Quality w/ a "marine" stamp on it.. for boats i guess, works great in a car.

We’re a cheap replacement. Works great.
