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

Hooked this up to replace my 20yr old marine audio 120w 2 channel amp. When I hooked it up worked fine until I started the engines. Loud whine came through the stereo as the suzuki 300 were running. Also whine was heard when using underwater lights. It was so bad could not keep radio on, had to shut it down. Hooked back up old amplifier works perfectly. This amp is a pyle of @#$#. I waited too long to hook it up or I would return it. Guess I'm stuck with it now....

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.

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

Decent amp but picks up alt whine spent hours searching for bad ground or wiring but it’s just the amp if your putting this in your car get a rca ground loop insulator and works good now

Great product, still in use after a hot and dirty year of bouncing around in my van!!😁
