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

Cost efficient way to help out with my sound system sounds clear works great for its smaller size, lower wattage amp but really help with higher cleaner sound then radio alone, seems to be holding up so far and doesn’t draw a lot of power

Works great and excellent sound

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

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.

Do not recommend. Very poor quality. Hooked up to a nice pioneer head unit and while this unit did make things louder, there was a lose of sound quality that was very noticeable. It should be noted that this was through new mid budget speakers. I would strongly suggest spending another 20-30 bucks for a better unit. I sent this one back and replaced it with a Crunch PDX 1000 for an additional 20 bucks and the difference is extremely noticeable. The Crunch is a more powerful amp, plus you get gain adjustment as well as a bass eq and channel specific crossover switches. The price for the Pyle is tempting, but, just don’t.
