Pyle 2.1 Bluetooth Marine Amplifier Receiver - Waterproof 4 Channel Wireless Bridgeable Audio Amp for Stereo Speaker with 400W Power Dual MOSFET Supply, GAIN Level & LED Indicator, Black - PLMRA410BT

This is a great little amp. It's easy to install pretty much anywhere if you know what you're doing. I have it wired up on my ATV pushing two BOSS 5.25" marine speakers. It gets loud enough to hear over the engine and the wind when I'm riding trails, and the sound quality doesn't suffer at volume. The waterproofing holds up to rain, mud holes, and washing off. Very satisfied with this amp.

Worked great when it worked in a weather tight enclosure on the family boat. Seems to have failed with no bluetooth connection available as mentioned in previous reviews...gambled and lost on this one.

Great amplifier for outdoor use! I have mine powering two kicker 6” tower speakers and the sound is amazing. The built in Bluetooth is great and connects so fast!

Installation was quite simple since I already had 12v power, ground and remote wiring installed for a subwoofer amp that was mounted next to this amp. The amp is relatively small, and that was nice. Plenty of mounting options available to squeeze it into.I chose this 4-channel amp to run the speakers in our boat which are two 6" speakers in the bow, two 6x9's at the helm, two 8" in the cabin and two 6" on the stern at the rear swim deck.Each set of speakers were wired to a different channel on the amp Bow#1, Helm#2, Cabin#3, Stern#4. Once power and grounds were connected, and RCA inputs were installed from the amp to the stereo, the amp powered up and operated fine. Sound was good. With the amp dials on max, sound output is sufficient enough to keep my stereo volume around 1/2 and it is plenty loud for us.I ordered the bluetooth version of this amp, and found that it also works well. If I turn the stereo off, I can connect my iphone via bluetooth directly to the amp, and play music/adjust the volume via my phone, so that works well for any friends/family that might want to jump in the boat and play their own music playlist, without physically having to connect to the stereo or deal with any wiring. So technicially, you dont even need a stereo in the boat. If I didnt already have the sub amp installed, I would have bought a 5 channel version of this, and hooked the sub to the 5th channel. We listen to the radio quite a bit, and dont have great cell service while on the water, so for us, the amp/stereo combo works best.You can mount this amp anywhere in the boat out of sight, and use your phone as your radio. Makes for less wiring, which is always nice. With the bluetooth connection feature and small size, this would also be a great amp for your golf cart or UTV/ATV. For the price, I think it's a win on all levels.

Good amp for the price, but the built-in Bluetooth functionality could be a lot better.The built-in Bluetooth receiver, when connected to a device (such as my iPhone or Nexus 7) and that device has an audio session open, emits very audible electronic interference noise (static/buzzing) through the connected speakers. It's a similar sound to that produced through headphones from cheap on-board audio on PC motherboards. Additionally, whenever a connected device starts or ends an audio session, the speakers produce a loud pop/click.Line-in has no such noise issues. With just line-in, the amp works great.The quality of the built-in receiver rivals that of the 1$ USB-powered Bluetooth receiver I purchased on eBay, i.e, absolute crap! The $1 receiver also adds noise to the line-out signal.I was hoping the built-in receiver on this product would be better. Otherwise, I would have purchased a cheaper amp with only line-in and add my own Bluetooth receiver.

Just what I need 👍🏽

The media could not be loaded. I liked that this amp has Bluetooth. It was an easy install, remote wire, ground, and 12v power. I mounted it with some small screws of my own, be sure to buy your own wiring cause this doesn’t come with any. 400w is plenty for what i use it for. I ran it to two speakers on the side of my console with channel 1 and 2. I believe you can run multiple speakers from a single channel though. Purchasing the pile tower speakers and mounting those next. Enjoy the new audio setup!

I got my amp and hooked it up in my boat i had everything on there correctly with the right wires and everything and the amo started to smoke and almost catch on fire after about 3 uses so do not buy
