Quick Amplifier Guide
POWER CONNECTION
The main power cable must be connected to the positive terminal of the vehicle battery to provide an adequate voltage source and minimize noise. There must be an in-line fuse within 18 inches of the battery. Connecting the battery terminal lead to any other point will reduce the power output and may cause noise and distortion. Use only 8 gauge or larger wire for this lead and connect it to the (+) terminal of the battery with the system fuse in line. Do not install the fuse in the fuse holder until the entire installation is completed.
GROUND CONNECTION
The ground terminal (GND) connection is also critical to the correct operation of the amplifier. Use a wire of the same gauge as the power connection and connect it between the ground terminal (GND) of the amplifier and a metal part of the vehicle close to the mounting location. This wire should be as short as possible and any paint or rust at the grounding point should be scraped away to provide a dean metal surface to which the end of the ground wire can be screwed or bolted.
REMOTE TURN-ON CONNECTION
The amplifier is turned on by applying +12V to the remote turn-on terminal (REM). The wire leading to this terminal should be connected to the remote lead from the car stereo which will provide the +12V only when the car stereo is turned on. If the car stereo does not provide a remote lead, the remote turn-on lead may be wired to an accessory terminal in the car’s fuse block. This will turn the amplifier on and off with the ignition key, regardless of whether the car stereo is on or off.
REMOTE TURN-ON CONNECTION
Wire the subwoofer terminal per the wiring diagram (right). Use 16 gauge wire between the enclosure terminal and the amplifier, for leads in excess of ten feet 14 gouge wire is recommended. When wiring the subwoofers, pay careful attention to the polarity of the terminals on the enclosure and make certain they correspond to the polarity on the amplifier.
SIGNAL (RCA) CONNECTION
Connect the low-level signal cables (RCA type) from your car stereo or WC to the input section on your amplifier as shown below.
REMOTE BASS KNOB (RBK) CONNECTION
Mounting the RBK at the front of the vehicle in an easy-to-reach location. Connect the remote level control using the supplied RJ-11 (telephone) cable. Plug one end into the amplifier and the other into the RBKThis will allow you to adjust the sub-level from the front of the vehicle
REMOTE BASS KNOB (RBK) CONNECTION
This is used to connect the speaker wires directly from the radio to the amplifier as on input signal (this is typically used on factory radios or any radio that does not. have RCA outputs) connect the White and White/Black to the left front speaker outputs (white to the positive (+) lead white/black to the negative (-) lead of the speaker do the same with the Grey and Grey/Block for the right front speaker (if you are using a 4 channel amp you will do the same for the Green and Green/Black the left rear speaker and the Purple and the Purple/Block to the right rear speaker).
“NOTE: SPECIAL SIGNAL GROUND
For High Level (speaker input) connection DO NOT CONNECT to normal high power
head units. This is special signal ground for vehicles that have speakers
referenced to chassis ground. Meaning only a positive wire goes to the speaker
connection. NO ground wire is connected If your vehicle has this setup, use
this wire. Otherwise DO NOT USE!!!
(‘The RBK remote Bass Knob is on an optional port that con be purchased from any authorized Derwin-Vega Mobile retailer)
