Amplifier's provide high-performance sound reinforcement for you're
mobile audio equipment. The Multi-Mode bridging capabilities allow
flexibility in hosting several different speaker configurations.
To achieve optimum performance, it is highly recommended that you read
this Owners Manual before beginning installation.
