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

Works well

The media could not be loaded. 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.

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.

Pretty good for the price I should of got the two channel since I’m only using two speakers it would’ve been smaller and easier to hide overall happy installed an on off switch connect find with Bluetooth it’s not the loudest but it’s acceptable bought two Boss atv speakers

I bought this little guy to install on my motorcycle. It is small enough to fit inside the faring and loud enough to hear on the the bike while doing 60. The sound quality is pretty good, nothing to bitch about. I have it hooked up to a receiver but also have the auxiliary input hooked up as well. THe blutooth works just fine, no problems as of yet. I would recommend this for anyone wanting a cost effective way of hearing your music over your pipes.

Small and seems to be made well. The gain knob didn’t seem to do anything. Also the “reverse polarity” button didn’t seem to do much at all. There is no filter knob. Only a gain knob and that didn’t seem to much like I said.. Bluetooth works great tho. Gets pretty loud with 4 6.5” Belva marine camouflage speakers.

I'm using this in my side by side. It's a perfect little amp and easy to hide somewhere on your machine. I love the volume switch it comes with. I bluetooth my phone to it and dont have to mess with my phone any further. You simply use the dash mounted knob to adjust the sound from there. It also comes with a dash mounted aux input but the bluetooth works perfectly. The bluetooth pics up my phone from about 25 feet away. You dont need a stereo reciever which is awesome.

Hello Everyone reading this,I’m not usually the one to write reviews but wow! This thing is amazing. I ordered one to put in a classic car while still retaining the original radio in the dashboard. It’s super small and easy to wire up like any other ordinary head unit. Audio is clear and the volume goes pretty loud.Would definitely recommend and I’ll be purchasing a couple more.
