Review on Pyle Channel Marine Amplifier Waterproof by Chris Shields

Bluetooth connection was important to me. Once paired, it will be in Bluetooth mode when you turn it on. If the paired device is within range and turned on, it will connect automatically. I connected it to the Revain Alexa device and it works great. The unit isn't 400W RMS, I'm guessing it could be 400W peak or around 25-30W RMS. I hooked it up to my 150W Polk OS70 outdoor speakers and at full volume it doesn't bother them much, but it's more than loud enough to fill a large room. It draws less than 4 amps at 12 volts...do the math. The good thing is that I don't get any distortion at full volume and it's more than loud enough for my purpose and I don't need more than half the volume. I use a bridged input because I don't need four channels. This helps get some more volume. If it suits your needs, consider it good value for money. I am happy with my usage.
