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 in the MBQR-2 remote level 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 Bass 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. Route two 2 gauge power cables directly to the vehicle battery with an in-line fuse.
