Description:

Rockville RXM8BT Marine 8 Channel Digital Class D Power Amplifier with Bluetooth Wireless Integration.
The Rockville Proton Series Marine amplifiers are engineered with advanced technologies. These amps are a full solution to your marine audio needs. Gone are the old days where people bring CD's on their boat or listen to FM radio that cuts in and out. Gone are the days where you need a receiver and multiple amplifiers to power your speakers. Gone are the days where you have wires running throughout your boat. Welcome to the marine system of the future! The Rockville RXM8BT will change your life! This is an 8 channel amplifier with Bluetooth built in! The Bluetooth will allow you to stream music wirelessly from a Bluetooth enabled MP3 player or smartphone. Of course the RXM8BT features ""zero noise"" RCA differential preamp inputs and preamp outputs for system expansion. This means you can connect any audio device through the RCA input. But it's the high quality Bluetooth that will blow you away. It offers advanced streaming from almost any music device. Now you can easily play your iTunes, Pandora, Rhapsody and Spotify directly from your smart phone directly to all 8 channels of your amplifier. Even more importantly though, is the capability of the 8 channel amplifier. We feel this is the best marine amplifier on the market even if it did not have the Bluetooth capability which it has. It offers more system flexibility and more power than anything even remotely close to this price. I almost forgot to mention how good the sound quality is. 

The Rockville Proton Series Marine amplifiers utilize Texas Instruments patented switching technology to deliver class-leading sonic performance and extremely high power from what seems like an impossibly miniature package.
