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.

Not bad for the money...now...with that being said let me say the first one i received was defective, i installed the amp and set everything to find that it was only operating like a 2 channel not a 4 channel it worked and even sounded pretty good but of course i purchased a 4 channel amp not a 2 channel...I contacted Pyle and they confirmed "yes it sounds like its defective" Pyle then proceeded to tell me that they would have no problem replacing if needed but i would have to pay shipping and an additional amount for them to take a look...so i contacted Amazon...they had no issue taking care of it and overnighted me another unit, the replacement works perfect and actually sounds pretty good for such a small amp...it is NOT 800 watts of course it only has a 10 amp fuse...but very compact, clear and pretty loud, works great in a Wrangler with no doors or top...overall not bad for the price!

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

Good.\nPlace

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

Nada que ver de cómo lo anuncian la verdad es una porquería en cuanto a sonido solo da 25 wats por canal . Tiene más salida el estereo que el amplificador.
