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 ampliers together, the nal impedance load of the
bridged ampliers 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 amplier to the SECONDARY amplier and set the Bridged Mode switch on
that amp to Input Slave. Do not input any signal to the Slave amplier’s RCA inputs. All settings will be controlled by the PRIMARY amplier including input gain levels. There is no
need to gain-match the two ampliers, it will occur automatically. The remote dash bass control should be plugged into the Master amplier and it will control both ampliers. 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 amplier’s outputs
together. PRIMARY amplifer’s positive (+) speaker terminal should be wired to the positive terminal of the subwoofer. SECONDARY amplier’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 amplier and the negative (-) terminal
of the SECONDARY amplier. When daisy-chaining two ampliers 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 ampliers,
eliminating the need to gain-match and crossover match your system between ampliers.
You can only bridge two of the same amplifiers together.
DO NOT BRIDGE DIFFERENT MODELS TOGETHER.
