Review on 🔊 Pyle Hydra Marine Amplifier - Upgraded Elite Series 800 Watt 4 Channel Micro Amplifier - Waterproof, GAIN Control, RCA Stereo Input, 3.5mm Jack, MP3 & Volume Control (PLMRMP3B) by Melissa Jones

Good. I was sucked in by a 100-watt RMS X4. With just two speakers in a tower case. but mostly even real 50 watts per channel. like my truck has power over you not impressed yet. The main unit drives another set of wired speakers at the same level as my floorstanding speakers, connected to the amp via an RCA input. I expected a lot more power from 6" floorstanding speakers. Hmm, even when the boat is running you can hear a very loud howling noise from the generator. I connected ground and current directly to the battery with a 6" meter and will do it again with the engine running The maximum power specification is of course inaccurate, but generally the RMS is at a stable level, and even when the amp is putting out 50% of the advertised 50 watts per channel of pure power, the full bandwidth is very strong, but I don't hear it unless there is an output level the RCA to my main unit needs adjusting, I have the input gain on the amp at max and it's still not too loud I should have done more research or even bought the same brand as in my truck.Black Ice model.Never gets hot.and running 4 speakers and my box subwoofer and it's impressive.Well good luck.The price was too good to be true .
