BOSS Audio MC900B Weatherproof Amplifier - 4-Channel, Bluetooth, 500W, Bluetooth Remote, Full Range, Class A/B, 4-8 Ohm Stable, Aux-in, RCA Outputs, USB Charging Review

Worked great for 3 months then died. This is the second person that has done this to me. Used in the golf cart, stored in a dry and heat-protected hold.

Very small and easy to hide. I'm installing in my 1990 Rover Mini, I didn't want to make a hole in the dashboard. So I bought this underseat fit, perfect for just 2 speakers as it's such a small car, works great

the front panel that controls the device is shorted! a wire on the back that needs to be moved to make it work and guess what no one has emailed asking for a replacement! 6 year guarantee? If someone can help me I can change this rating!

Please, sounds great with 4 Kenwood 6.5 speakers. I think it's a bang for your buck. I wish the cables were interchangeable, it's very possible that the 12 gauge power cable isn't thick enough and the speaker cables can fail after a few years in marine environments. Great sound, easy installation.

Install this unit in a vintage truck so you can listen to music from your phone and leave the 3-hole head unit in the dash to create an original to get appearance. Installation was pretty easy and it fits easily under the passenger side of my seat. While it connects flawlessly to my phone via Bluetooth, I'm a bit disappointed that the front and rear power can't be adjusted. My rear speakers don't hit as hard as I'd like.

We operate with our four outdoor pool speakers. Compact and easy to use, this thing has amazing performance considering its low power requirements. My wife loves bluetooth and I love the aux cable. Despite being in a relatively tight, sealed case with a good power adapter (which you'll need if you want to run it on AC power rather than a battery), heat wasn't an issue. This thing is actually loud enough to offend our neighbors 300 feet away if we're not careful.

Bought for a golf cart. The amp is smaller than advertised which was a bonus. The size makes it easy to install almost anywhere. The flush-mounted blue-tooth control panel comes with ample lanyard to run cables in excess of 10 feet. The installation is completed in a few minutes. Paired with 6.5" Polk speakers. You can increase the phone volume and the volume on the control panel. Thanks to the amplifier, these speakers scream absolutely without any distortion. So far, it's good. I'm happy with

So after I installed the amplifier on my boat it worked perfectly for 1 trip on the lake. 1 month later we went on a 4 day sea voyage which was the 2nd voyage for the amps. The first day it worked perfectly, and the second day it wouldn't connect to any device via Bluetooth. So we had 3 days without music. I bought the $9.99 3 year warranty so Revain is replacing it. I hope the next one lasts longer than a month. (Also, there's a way to hardwire your phone. If you're buying this amp, I highly…

So far this system works well and sounds pretty good for the price. Use it to power 4 boat speakers and 2 separate amplifiers for subwoofers and wake bar speakers. Sound is impressive enough with just four main speakers (better than the Clarion m303 it replaced). I had an issue with no sound over bluetooth despite showing playback and connecting with controls still working. I then found that the controller was red instead of blue and remembered having pressed the power button on a previous use.
