This Pyle Hydra amp will power your speakers on the dock, in your boat, or by the pool--it's completely waterproof. This 4-channel, 400-watt marine amp takes both high- and low-level inputs, so it's compatible with a variety of head units and sources. Remote turn/on off makes controlling the amp a breeze, and gold-plated RCA inputs mean it won't be a weak link in your setup.
Power your speakers on the dock, in your boat, or by the pool. View a connection diagram.Input Options
The PLMRA400 features low-level RCA inputs for sources that use RCA-type connectors. If your marine receiver lacks RCA output jacks, you can connect speaker output leads to the high-level terminal inputs.
Input Level Control
Adjust the line level input for the least amount of distortion to match your source unit.
Protection
Protect the amp and your vehicle's electrical system from short circuit conditions with built-in fuse protection, along with overload, thermal and short circuit protection. A heavy duty aluminum alloy heatsink helps prevent any thermal issues.
4 or 8 Ohm Speaker Impedance
The PLMRA400 is ready for either 4- or 8-ohm speakers, in pair.
Remote Turn-On/Off
Wire the PLMRA400 to turn on and off in tandem with your receiver/head unit.

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. I can also offer advice if anyone needs it via msouhlas@yahoo.com.Mark

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.

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

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 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....😒

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

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.

Absolutely love this unit.Sound is excellent for my application running 4 speakers in a wake board tower on my boat. Love the white as it does not heat up in the sun and the layout of the unit is proper. If you need a good basic setup and were debating trying out Pyle give it a shot. Its good solid product.

NACHTRAG:Das neu bestellte Gerät hatte nach kurzer Zeit den selben Defekt! Schaltet über Remoteleitung NICHT mehr ab. Es bleibt ebenfalls ständig eingeschalten und saugt die Batterie leer.Ich habe den Verstärker im Dez. 2019 bestellt und im Frühling 2020 zu Beginn der Motorradsaison hinter einer Motorrad-Fairing verbaut. Was mir schon bei Erhalt des Verstärkers auffiel war, dass zwei Schrauben der Abdeckplatte locker, bzw. deren Gewinde durchgedreht waren. Ich musste diese Schrauben durch größere ersetzen, da die Abdeckplatte dadurch locker war und schepperte. Was ich auch komisch fand war, dass eine der lockeren Schrauben ein Blechtreibegewinde und eine ein Feingewinde hatte. Ebenfalls waren die Halterungen der Kabelanschlüsse gebrochen. Ich denke die Schrauben dieser Halterungen wurden zu fest eingedreht und dadurch die Hülsen gesprengt. Im großen und ganzen eine sehr schlampige Verarbeitung, bei zumindest meinem Gerät. Der Verstärker wurde über die Remoteleitung, am Zündschloss, zum ein und ausschalten angeschlossen. Dies funktionierte auch etwa 4 Wochen tadellos, dann ließ sich der Verstärker nicht mehr über die Remoteleitung abschalten. Er blieb permanent an, auch nach abklemmen der Remoteleitung. Erst nach entfernen der Sicherung an der Hauptleitung ging er aus.Nach Reklamationsversuch durch einen sehr netten Amazonmitarbeiter direkt beim Lieferanten, erklärte sich dieser nicht bereit ein Ersatzgerät zu senden, mit der Begründung er hätte sein Lager in GB und es ginge aus diesem Grund nicht. Amazon nahm dann das Gerät anstandslos zurück und erstattete den Kaufpreis.Da ich jedoch an meinem Motorrad alles so verkabelt habe, dass die Anschlüsse und Kabel genau für den Pyle Verstärker passen, war ich gezwungen den Verstärker erneut zu bestellen und zwar um ein paar Euro teurer, da der Preis zwischenzeitlich gestiegen war. Und siehe da, dieses Gerät wurde in GB aufgegeben, wo vorher genau aus diesem Grund keine Ersatzlieferung möglich war.Angekommen ist dann ein Gerät das entweder ein Rückläufer, ein gebrauchtes, oder Reparaturgerät war.Die Verpackung war nicht Original verschlossen, die Siegel mit Tesastreifen zu geklebt und die Plastikhülle aufgerissen (siehe Bilder). Die Halterungen sind bei diesem Gerät ebenfalls gebrochen. Ich habe den Verstärker jetzt trotzdem verbaut, - er funktioniert zur Zeit. Noch einmal auf ein Tauschgerät zu warten war mir dann zu blöd. Jedenfalls würde ich diese Marke anhand der schlampigen Verarbeitung und der Tatsache, dass ich nach Neubestellung kein neues Gerät erhielt, hier nicht wieder kaufen. Mit dem Klang bin ich soweit zufrieden.Ob der Verstärker wirklich Wasserdicht ist wird sich weisen. Das Gehäuse ist nicht abgedichtet und hat sehr große Spaltmaße. Wasser wird hier ungehindert überall rein laufen.
