Pyle Hydra Marine Amplifier - Upgraded Elite Series 400 Watt 4 Channel Audio Amplifier, Waterproof, 12 volt, Dual MOSFET Power Supply, GAIN Level Controls, RCA Stereo Input & LED Indicator - PLMRA400

This is a great addition to my Jensen MSR3007 in a SeaDoo jet boat. I am not sure why many folks are getting poor quality or results, but if you know what you are doing, this unit works as advertized.I made up a pair of Molex connectors so that I can either insert or bypass the amplifier using the factory harness when not using the wake tower and wake tower speakers (Boss Marine MRWT69W 6x9" 4-way speakers), or when I do not want to consume more battery power while out on the water. I also replaced the original Jensen speakers in the boat with Boss Marine MR60W 6.5" 2-way speakers.I first tested the 4 speakers without the amp and thought that I would not need the amp because the sound was adequate. However, after testing with the amp, I changed my mind. The sound is very clear and _much louder than with the Jensen 3007 alone. I used the 4 low impedance inputs connected to the speaker outputs of the Jensen to maintain front/rear fader control and adjusted the gain in accordance with the installation instructions.Also added the Kinivo BT adapter for audio streaming and telephone calls from my Android cell phone.Finally, will be adding the wired MWR100 remote control for the Jensen unit on the swim platform very soon. Voila... a totally fantastic upgrade for the boat, all ordered through Amazon. I would recommend a professional installation if one is not 100% confident in their technical ability.

Put this in my 2003 jeep TJ. I have a cheap media reciever installed running this with 4 rca inputs. It is powering 4, 5.25inch pioneer speakers. I can really crank this up. It will not win any awards but it is loud enough. I cranked my stereo all the way up and adjusted the gain almost completely to max with no distortion. My biggest issue was getting a good enough ground to eliminate the alternator whine.Bare metal is the key to that. So for $100 I have a pretty kick as stereo in my jeep TJ. Speakers $40. Head unit $20. This amp $37. I already had 2 sets of RCA cables and the speaker wire. I did spend $3 on a 30 amp water proof fuse holder that I ran to the battery for this amp. I am adding a subwoofer as we speak just because I got the bug. Looking to spend under $40 total on that as well.

Pretty impressed with this inexpensive little amp. I AM a bit of an audiophile, I like CLEAN music and sometimes like it LOUD without distortion. I have a competition quality $4000 stereo consisting of all Phoenix Gold amps three in fact, two Kicker Solobaric 12's, Kicker surround speakers for the rest of my system and it all puts together a CLEAN very LOUD awesome stereo that sets off car alarms and can be heard for blocks and blocks if I want it to be, but unfortunately none of that is waterproof for my Jeep.I figured I'd give this little guy a try, it is running two 6.5 Sony marine speakers in the doors and the Infinity Reference 6912m 6 x 9-Inch 300-Watt High-Performance 2-Way Marine Loudspeaker (Pair) in the back ( purchased here on Amazon as well ) and sounds pretty darn good,To tell you the truth for less than a Grant, this IS a really impressive little amplifier.I'm going to get the two channel amp as well and a couple of inexpensive Pyle 10's to add some MORE bass to the Jeep ( really can't believe how cheap this stuff is, I always considered pyle as just that a PILE of China *%*#& but I admit I was wrong,I have had nothing but GOOD experiences with this low cost audio ).It is great to have a good sounding stereo in my Jeep, that I don't really have to worry about it getting wet or worrying to much about being a target for thieves, most folks consider Pyle products the way I USED to.PLUS, MY ENTIRE SYSTEM COST LEES THAN ONE SPEAKER IN MY PREVIOUS SETUP - THAT ALONE IS AWESOME

Excelente

I have two of these... both out of box failures. NO Output. No audio or voltage. Run them with RCA inputs, from 2 reliable tested sources. NO audio out. Can one figure that there is a remote chance of getting 2 out of box failure? That was my silly thinking. But.. I did...So, trying to find customers support was a hassle, there is a trucking company with same name...oh, did I mention there is no support number on the documents... yea.I call the mother companies support. As expected went to off shore and the Missy had to consult her scripts. She advised me to return to Amazon.So.. I strongly suggest to not buy either the 400 or the 402.. if worked would be a great product... ya get what ya pay for!Pouting in Martinsville Virginia....😒

For the price point it will be hard to beat this amp. Easy to install, small footprint and just works. Runs cool in my center console. I actually have the pyle running 4 fusion 6.5" and a kicker10" sub (temporarily) now and amazed how well it sounds with the sub added to one of the back channels. I have another amp ordered just because I want a 5th ch for the sub and so that I can wire it properly. But still blown away how well the Pyle amp is working with the price point.

I purchased this amplifier for my boat, I didnt want to spend much money knowing the harsh environmnet it would be operating. What I found once installed was this, for the money I spent this was the perfect amp. Just enough power to kick the Pyle 120W speakers I bought coupled to a clarion DB345MP Deck utilizing low power inputs, front and rear power output is suficient to supply bass and treble to enjoy the music, definately not a kicker, you have to adjust output down to prevent signal cutoff while playing loud music. There is definately crossover noise from front to rear and visaversa when using the fader, the Noise issolation is poor as well between all channels. For the money the amp performs well enough for the boat and its environment. I would purchase the components again if I had the chance for this type of use only. It's only been a few weeks now I can't speak of longevity.I would not recommend this for your vehicle or if you're a music connosur. Spend the extra money and purchase better equipment.JW
