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 RockvilIe 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.
The RockvilIe 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. The Proton Series' dimensions are made possible by its outstanding efficient class D design which is over 90%efficient. The result is more power in your boat with less current drain. Proton Series amplifiers are 2 ohm stable in stereo and 4 ohm in mono.There are so many options of configurations. Any 2 channels can be bridged to 1 channel.
