Pyle 800W 4-Channel Hydra Marine Micro Amplifier - Waterproof - GAIN Level Controls - RCA Stereo Input - 3.5mm Jack - MP3 - Volume Control - Short Protection - For Boat & Vehicle Use - PLMRMP3B

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.

Does not work out of the box. Of course I waited a few months to install it in my rzr due to life getting in the way so the return option is no longer available. Good thing it was a cheap price, Get what you pay for... The infinity radio works; using same power source and ground source so I know that is not it. Test light shows good power from bat and ACC going into the amp. But still no go. Just a note, I am not a first timer. I have been installing and building custom car audio for about 25 yrs and this device is about as simple as they come.

Great little amp. Was quite surprised with it being Pyle. Never had good success with their products till now. Lots of people wrote reviews about it being under powered. At first I had it hooked up with only two channels with one speaker on each channel. Was not very loud at all. Turned the gain knob up half way and was significantly louder. But was still not loud enough to hear over sound of wind at hwy speeds. As soon as I hooked up 2 more speakers one to each of the other channels it really came to life. Apparently this amp needed a load on all 4 channels because I got double the volumn off the first two speakers when the second two were hooked up. Two 400 watt Pyle hydra speakers in my saddle bags. Both running off channel 1 and 2. And 2 140 watt Rockville speakers up front. Pioneer head unit supplying rca audio to amp and rca audio to a 400 watt powered rockville sub. Very pleased with my bikes stereo.

This thing works good and sounds good however it's not 800w output it's actually weaker than the standard 200 coming from the radio itself

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 11 The 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 seat Cons: NOT 800W (but plenty loud), not bridgeable, nothing else really In 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

Working good so far

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.

I've installed more car stereos than I can remember. This amp lacks a power indicator led. It is very difficult to troubleshoot if I have the power connected correctly or if its the input wires or... I got it to produce sound and it was definitely more powerful than the factory stereo. I had it connected using only one channel. I tried to rewire it to bridge the two channels. Crazy alternator noise, it apparently cannot be bridged. I couldn't get the amp to turn off. I discovered I could lightly tap the amp and it would send pops and crackles to the speakers. This continued to happen even after disconnecting the remote wire. I uninstalled it. I will pass on having my battery dead every time I don't start the car for a few hours.

Fantastic

Llego en tiempo y forma

Ok

Allg ood

Muy pobre en la cuestión de sonido, no me levanta casi nada las bocinas, no es potente en realidad, compren algo bueno,
