Pyle Hydra Marine Amplifier - Upgraded Elite Series 800 Watt 4 Channel Micro Amplifier - Waterproof, GAIN Level Controls, RCA Stereo Input, 3.5mm Jack, MP3 & Volume Control (PLMRMP3B)

Amazing amp at a very reasonable price. I have been using pyle for years and have never had any issues. Was just time for an upgrade and couldn't be happier. Easy to install. Love having the accessible volume control right next to the head unit. Plenty of room to grow with backup channels if needed. Atleast for my setup.

Worked for 30 minutes then it started a humming sound.

Works as it should

Pyle has been around for decades. Installation of this small amplifier was very simple and straight forward. I use or should say used this to power four 6" 3 way speakers in my boat. It does amplify the sound however the amp keeps cutting out. I used to work as a audio installer, and I am sure that I connected everything correctly. I did double check all my connections and they are secure. I have since pulled the amp from my boat and installed a different one. In fairness, the amplifier does perform like it should, the item was shipped quickly and arrived with excellent packaging. I have no complaints about the seller or the amp. I might have received a dud...

First of all, all the other reviewers are right. This is obviously not 100w RMS per channel. It has a 10amp fuse and 12ga power/ground leads, so really it cant be over 150w RMS total. I bought it knowing that so I wasn't disappointed. Really, its probably around 30w-40w RMS per channel. I have it in my jeep wrangler yj, I got this because the internal amp in my headunit burned up from water, and WOW!! I used to have my headunit on max and still only hear every other word (over engine/wind) with the top on, but now I ride with the top off with the radio on 20 out of 35 and I can here it clearly but if i go to 30 it distorts to something awful [I never get that loud anyway]. I have it powering 2 4x6's and 2 6.5's. Make sure you do 2 things though when installing. If you dont plan on using the volume knob with the kit (like me) turn the volume control/""gain" knob up to about 2/3's to 3/4 of the way [NOT ALL THE WAY or it distorts] before you install and make sure you strip the black/red/blue wires more than whats already stripped. I didn't and It wouldnt play so I re-did it and stripped it more and now it plays. Anybody who says this isnt loud enough probably did not turn up the volume control because it goes from the it being a 4 to the volume going to 11The pros: I can actually hear my tunes going down the road, A lot of sound for a 40$ amp, easy to install, water resistant, very small/compact, plenty of power for me. Plays stereo sound, black color hides well under my seatCons: NOT 800W (but plenty loud), not bridgeable, nothing else reallyIn short, If you buy this knowing that its power is completely overrated you won't be dissapointed. It may have been the best 40$ i've spent on my Jeep in a while. If you get this for powering say a subwoofer or to bridge the channels, It just wont happen. I havent tried using it to play 2ohms but It is plenty of power for me.Now I just need a subwoofer :D

Great little amp. Don't forget to factory reset your fusion ms-ra210 radio, turn internal amp off, and start with hydro gain off and bring up slowly. Otherwise rca outputs on fusion radio will not work. And internal amp will overheat hydro.

I can not attest to what kind of sound is produced as it arrived 3 days after I ordered it DOA , I spent 4 hours in 90+ degree temps with high humidity trying to get this until to work and gave up for the day spent from the heat ... spent 2 more hours the next morning before I threw in the towel .... no way to tell if it is powering on ( no indicator lights ) I never got sound so assuming since it was wired correctly it just didnt work ... also determined it was a return because 1)box only taped shut no shrink wrap 2) missing waterproof bag 3) some of the wires did not have wire ties on them .... empty plastic bag inside I suspect was supposed to have part of the wiring harness in it .... all that said no way its 800 watts it only has a 10 amp fuse so it would be 140 watt MAX if it was 100% efficient ( amps x max voltage 14.4 ) so that would mean best case scenario 35 watt rms per channel but again that would be at 100% efficiency ... amps normally are closer to 75-80% efficient ... I would guess this is probably about 20 watts per channel ( if it works ) in my case its ZERO watts per channel

This worked great. Like some of the others have said...I'm not sure if this is truly 800 watts or not but for my purposes it more than did the job. I put this on my 1600 Nomad to work with a Pioneer Headset and 4-150 Watt Boss Marine Speakers mounted in my Reckless Fairing. I mounted the amp with heavy duty velcro to the top of the reciever and it hasn't moved a hair. The boost that this gives my speakers is about all I can hope for on a motorcycle ride. The volume level on my radio goes up to 55 max and while traveling at 75 mph on the highway I only have to use about 35-40 of that volume range. It pushed the vocals and mid range sound to a level that can be easily understood while getting up down the highway. Would definitely recommend if you're looking for an affordable amp to push your speakers to the point where you can actually enjoy your tunes with the wind to your back.
