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

I needed an amp for my jeep wrangler. I wasn't gonna spend a lot due to weather and possible theft. This little amp was perfect. I have it running 2 sets of 5.25's and they sound great.

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.

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

Ordered this amp for my jeep and installed along with a new radio. The amp had an issue after a couple of hours and stopped working. Put in for a replacement and got the replacement in two days (faster shipping than the original). I haven't reinstalled yet since I wired up directly to radio after issue with amp but I have to say there was no issue with replacing item. I would order again because while the original worked it was as advertised.

This was a used amp. No where I saw it said refurbished or used. No input cables, was dirty and had duct tape on it. Thought I would try it anyway. Will not power up. Disappointed with Amazon on this product.

I just wrote a terrible review for another Pyle item I bought here. I thought it was only fair that I say my piece on this one too. I've owned this for 7 years and it's been placed on 4 boats since then. It worked great when it was new and it still works amazingly well, nice deep base and totally throws down. An excellent buy if you're considering it

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

Packaged well and shipped fast seems to work pretty good far. Great price.
