CONNECTIONS

Figure 4. BTX250 connections and ter- minals.

B+: Connect a wire (at least 4mm2) between the vehicle’s + (positive) bat- tery terminal and the "+BATT" terminal on BTX250. You must install a fuse holder with a 15A fuse within 50cm of the battery. Route the power wire through a grommet in the vehicle’s fire- wall.

If there is no factory grommet available, you must install one.

B–: Connect a wire (at least 4mm2)

between the "GND" terminal on BTX250 and a bare metal surface near the mounting location. You may need to scrape away some paint from the metal surface to insure a good connection. Use a screw and a lock (star) washer. Remote: Connect a wire between the remote terminal on BTX250 and the remote output wire on your head unit. This wire should provide between +5VDC and +12VDC when the head unit is on and no voltage when the unit is off.

INPUT CONNECTIONS

Note: BTX250 is equipped with two line-level (RCA) inputs and two speaker-level inputs.

Figure 5, Input connections

Head units with dedicated subwoofer outputs (line-level): Connect the subwoofer output from the head unit to the line-level inputs.

Head units with two line-level out- puts and two (or four) speaker-level outputs: Connect the two line-level outputs from the head unit to the line- level input on BTX250. Or connect two speaker-level outputs from the head unit to the Universal Interface inputs on BTX250, which correspond to the linelevel inputs.

Note: The Universal Interface input wiring harness included with BTX250 is color coded to correspond with the speaker-level outputs of many after- market head units and adapters sold as accessories.
