REF1.800

Linking Mono Amplifiers

DUAL AMP INSTALLATION PROCEDURE:

1.Connect the amp LINE INPUTS to the Radio/CD player full range or mono line out puts with good quality RCA interconnect cables.

2.Plug the MBQR-2 level remote module into the amp REMOTE INPUT jack on the Master amp. This will allow the Master amp to control both Master and Slave amps with just one Remote.

3.Connect an RCA jumper cable from the Master amp MASTER OUTPUT to the Slave amp SLAVE INPUT. Note: This will “link” the amps so that the Master amp crossover switches will control both the Master and Slave amps. The Slave amp crossover switches will be bypassed.

4.Make sure that the MASTER amps’ MODE switch is in the Master Out position. Next you need to make sure that the SLAVE amps’ MODE switch is in the Slave In position.

5.Route two 4 gauge power cables directly to the vehicle battery with an in-line fuse.

6.Connect two 4 gauge ground cables directly to the chassis with in 36” of the amp.

-Be sure to remove any paint or primer from the ground point.

-Use a nut, bolt and lock washer to secure the ground cable to the chassis ground.

7.Connect the subwoofer(s) in accordance to the diagrams below.

8.Connect a 12 gauge jumper from Master amp speaker - to Slave amp speaker - as shown below.

IMPORTANT: Please understand that each amplifier is stable to 1 Ohm, but when linking a pair as indicated below you can not link below 2 Ohms. You can successfully run one DVC 4 Ohm sub, two SVC 4 Ohm subs or two DVC 2 Ohm subs to get your 2 Ohm final load.
