Pyle 200W RMS 4-Channel Marine Amplifier - Bluetooth Wireless Audio Streaming - Waterproof - Full Range Stereo w/ RCA - High Crossover HD Music - Multi-Channel System - Compact & Powerful - PLMRMB4CB

Easy install, sounds great on the boat, I don't really play at super loud volumes but the power seems decent. Connects to my phone very easily and the volume control knob makes it very handy not having to have your phone in your hand to turn it up or down. For the price I am very pleased so far.

Owned prior model without Bluetooth but needed to upgrade to something more up to date. This thing really elevated my outdoor sound system! Sounds really good with the four 6.5 outdoor speakers it's pushing! Really love the Bluetooth!

Edit 10/19/2020 (updated to 1 star): After not quite a month of use, the 'lil amp is dead. It started with the sound cutting out and breaking up. Almost like a CD skipping. About a week later, the amp is no longer discoverable with bluetooth and the RCA inputs do nothing. I've checked over all my connections and the fuse. All the wiring is good, but all it will do is flash that little red LED on top. No output. I reached out to Pyle to ask about a warranty claim, but received no response (despite their claimed 1 year warranty). Today is the deadline for my Amazon return, so I will not be holding my breath for a response from the manufacturer. Back to the warehouse it goes.Edit 7/16/2021:The replacement amp (from Amazon) died in March of this year and I finally got around to ripping it out of my car (again). It won't turn on at all. No LED. No Bluetooth. No sound. Time to look for something higher quality. This thing is junk.Original Review (3 stars):Let me start by saying that I did read the reviews, so I had a decent idea of what I was buying. A couple things did take me by surprise though.The good:- This amp is tiny, about the size of a graphing calculator. You'll have no problem stuffing this somewhere out of sight. In my case, it was under a seat.- Bluetooth connection works well and connects automatically. The little red LED flashes then becomes solid when connected.- No head unit is required, but it does have RCA inputs if you want to use them.- It draws almost no power so it doesn't get hot (see below).- It's really really cheap.The bad:- Either the advertised wattage is a joke or Pyle figured out how to break Ohms law. The power wire is 16 AWG and it only comes with a 10A fuse. You're not pushing 200W through a 10A fuse let alone 4 channels at 200W. The fuse is sized to the unit so you can draw conclusions on that.- The bass is exceptional...ly poor. As in there is none. Part of this could be my old speakers. It also might have to do with the bluetooth connection. I haven't tried the RCA inputs yet. I have a feeling it's just a lack of power.- The volume knob works ok from 0 to about half way. Beyond half volume, it pretty much doesn't do anything. The knob is cheap feeling plastic. Not a huge deal, but it would be nice to have an option to upgrade to something a bit nicer looking.The unknown:- Since this is mounted under the seat in my car, I don't expect to have to worry too much about water intrusion. I mounted it on some plastic standoffs so it would stay relatively dry if the floorboards happen to get wet.- I finished the installation yesterday so I haven't tested out the longevity. It appears to be pretty decent in the looks/heft category so I'm hoping the electronics last a while. If not, I have all the wiring installed to upgrade to something a bit nicer.Overall, I would say this is a decent little unit for the price. If you just want something that connects to your phone and makes noise, this does exactly that. I'm using it in my classic car so that I didn't have to cut up the dashboard and change out the original radio just for bluetooth. I will mainly be using it for GPS directions while driving and it seems to work well for that. It does play music, but if you want any sort of sound quality, I would probably keep looking.

Works good but volume knob fell off and into the water

These little amps are awesome. I use them in my sxs and rat rod truck. Use them instead of a radio.

I paired this amp with two 6.5” Boss speakers and two (super cheap) tweeters. The installation was very simple. Although, I do have some experience with car audio. The Boss speakers sound great, but the tweeters are almost inaudible. Definitely not the amp’s fault. I will remove those and add two 5.25” speakers up front. I would definitely recommend this product based on my limited use.

Good sound not as powerful as rated. distortion after heating up, needs to be left in open air or a fan if in a compartment!

Easy installation on a golf cart and sounds great ! Very happy with this item so far!

Tuve problemas al conectar los conectores se tiene que checar qué estén alineados los pines de cobre,, pero tiene buena calidad de sonido

nothing like 1200w, not even peak power. Would be lucky if its 10w per channel, I am assuming they use crazy number to get to peak power and at 1ohm.I wanted it to run 2 8 inch full range speakers and its not even able to do that, I will buy something more suitable

Mi opinión acerca de este amplificador es variada puesto a pesar que cumple con la tarea deja algo que desear compensado con los accesorios con los que trae en primer lugar tiene suficiente potencia para alzar cuatro bocinas de 8 pulgadas 75 RMS pero no las lleva más allá de la mitad de potencia que ofrecen estás esto debido a que apesar que la caja indica 200 RMS no cuenta con esa potencia en imágenes la esperaba un poco más grande pero es del tamaño de una palma los accesorios con los que cuenta bastan para hacer todo tipo de conexión y el Bluetooth es de mucha ayuda este es un gran amplificador para pequeños proyectos que no requieran mucha potencia real pero basta para levantar bocinas medianas los materiales son de calidad pero en mi caso el aparato produce un pequeño ruido blanco cuando no tiene algo conectado y se hace más fuerte si cambio la sensibilidad del aparato he decido quedarmelo únicamente por la función Bluetooth puesto que es de gran ayuda cuando no hay forma de dejarlo conectado con jack3.5 o rca pero no quede satisfecho del todo por la falta de potencia

Se mira bien el articulo, solo que duró muy poco el funcionamiento del Bluetooth, después de 4 meses ya no quiso funcionar.

still trying to get it working
