WIRING
There are 5 wires to connect to the BA-2DD for proper operation. Make all connections before plugging the
wire harness into the mating socket on the amplifier.
1. Red Wire with Fuse: Connect this wire to a source of + 12 volts which does not turn off with the ignition
key. It may also be connected directly to the positive (+) terminal of the battery.
2. Black Wire: Secure this wire using a screw or bolt on a grounded metal surface of the vehicle. Clean-away
any rust, dirt, or paint from the surface to make sure a good connection is made.
3. Blue Wire: This wire activates the BA-2DD when the stereo system is turned on. Connect it to the "Power
Antenna" lead from your car stereo. If your car stereo does not have or you cannot locate the Power
.
Antenna lead, the blue wire can be connected to a source of
+
12 volts which is turned on and off with the
ignition switch. In this case, the BA-2DD will be activated whenever the ignition switch is turned on, whether
the car stereo is on or off.
4. Green Wire: Splice this wire to the wire going to the positive (+) terminal (sometimes indicated by a red
dot) of the left speaker of your stereo system.
5. G ray Wire: Splice this wire to the wire going to the positive (+) terminal (sometimes indicated by a red dot)
of the right speaker of your stereo system.
This completes the wiring of the BA-2DD. Re-check all connections to make sure they are secure and well
insulated before plugging the harness connector into the socket on the BA-2DD.

Operation of the BA-2DD is simple. If wired correctly, the amplifier will automatically be activated when the
car stereo is turned on (orwhen the ignition switch is turned on). Adjustthe volume control of the stereo system
to a normal listening level. Adjust the Gain control on the BA-2DD up or down to achieve the level of bass
desired and match the output of the unit to that of the rest of you r system. Once the proper setting of the Gain
control is found, it should be left at that position and no further adjustment of the system is necessary.
