Rockville dB Series User Manual

The dB14, dB15, and dB16 can be bridged together for double the power output into a single 4-ohm load. Remember, when bridging
amplifers you must bridge them to a 4 ohm load.
Input the head unit signal into the MASTER amplifer and set the Bridged Mode switch to Output Master. Use a MONO RCA to RCA 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 left and right inputs. 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.
This same input/control system can be utilized when daisy chaining two amplifers to two independent 2 ohm woofers as long as you
don’tbridge the two ampliers outputs together.
You can only bridge 2 of the same amplifiers together. DO NOT bridge different models together.
When bridging two ampliers together, the nal impedance load of the bridged ampliers should be no lower than 4-ohms. Double power
will occur at 4-ohms. Master amplifers positive (+) speaker terminal should be wired to the positive terminal of the subwoofer.
Slave ampliers positive (+) speaker terminal should be wired to negative terminal of the subwoofer. Connect a heavy gauge wire (12 Gauge)
between the negative (-) terminal of the Master amplier and the Negative (-) terminal of the Slave amplier.
When daisy chaining two ampliers for independent woofers, wire up the the woofers as you would typically wire them when installing
individual systems, even down to 2-ohm. By using the Master/Slave input confguration you gain the advantage of having one amplifer’s
preamp section control both ampliers, eliminating the need to gain match and crossover match your system between ampliers.
