Twin Amp Bridging (dB14, dB15, dB16 only)

The dB14, dB15, and dB16 can be bridged together for double the power output into a single 4-ohm load. 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. Input the head unit signal into the PRIMARY 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 PRIMARY amplier to the SECONDARY amplier and set the Bridged Mode switch on

that amp to Input Slave. Do not input any signal to the Slave amplier’s RCA inputs. All settings will be controlled by the PRIMARY 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 into the Master amplier and it will control both ampliers. This

same input/output control system can be utilized when daisy-chaining two amplifers to two independent 2-ohm woofers as long as you don’t bridge the two amplier’s outputs

together. PRIMARY amplifer’s positive (+) speaker terminal should be wired to the positive terminal of the subwoofer. SECONDARY amplier’s positive (+) speaker terminal should

be wired to the negative terminal of the subwoofer. Connect a heavy gauge wire (12-Gauge) between the negative (-) terminal of the PRIMARY amplier and the negative (-) terminal

of the SECONDARY 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 PRIMARY/SECONDARY 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.

You can only bridge two of the same ampliﬁers together.

DO NOT BRIDGE DIFFERENT MODELS TOGETHER.
