The RXDM4 can be bridged together for double the power output into a 2-ohm load. Though each amp is 1 ohm stable,

when bridging ampliers, you must bridge them to a 2 ohm load.

Input the head unit signal into the MASTER amplier and set the Bridged Mode switch to Output Master. Use the

supplied DATA CABLE to send the fully processed signal from the MASTER amplier to the secondary SLAVE amplier

and set the Bridged Mode switch to Input Slave. Do not input any RCA signals into the Slave amplier.

All crossover controls, Bass Drive, frequency settings, and subsonic lter settings will be controlled by the Master

Amplier including input gain levels. There is no need to gain match the two ampliers, it will occur automatically. The

remote dash bass control should be plugged in to the Master amplier and it will control both ampliers.

Make sure to use the supplied DATA CABLE for linking of the ampliers and not the dash board bass remote cable or

any other phone jack cable. If you misplace your cable, contact Rockville or your local dealer to procure a new one.

This same input/control system can be utilized when daisy chaining two ampliers to two independent 1 ohm woofers

as long as you don’t bridge the two ampliers outputs together.
