The ground wire should be of the same gauge wire as the power wire. As a rule of thumb, use as short length of wire as possible. Find a location near the MaxxBass® Processor that is metal ( the floor is ideal) and clean an area about the size of a quarter to bare metal. Drill a pilot hole in the middle of this area. Terminate the wire with a ring connector and attach it to the bare metal using a #8 sheet metal screw and washer (not supplied). We suggest crimping and/or soldering this connection. After the connection is complete, coat the area with silicone or some similar material to prevent rust from developing.
Finally, the remote IN wire needs to connect to the "Amplifier Remote" lead of the head unit. This wire supplies a 12 volt signal to the MaxxBass® Processor when the main System is activated. The remote OUT wire is to be connected to the remote input of the source amplifier or to and "optional" relay to activate multiple amplifiers. Once you have routed the power, ground, and remote wires through the vehicle, it is time to connect the wires to the MaxxBass® Processor. Be sure that you have not reconnected the ground cable to the negative post of the battery.
NOTE: Refer to the diagram of the system shown in MaxxBass® Outline and Dimensions for connection points.
Cut off the excess wire and, using the wire strippers, strip the power, ground and remote cables about 1/8 inch. Locate the power, ground, and remote IN/OUT wires of the power plug (supplied). We again, suggest crimping and or soldering each connection separately to insure no damage to the unit or the audio system. Check that each connection is tight. If the wires are secure, the plug may be inserted into the MaxxBass® Processor.
