INSTALLATION Typical Wire Routing BATTERY Main Power Connections Connect BAT+, GND and REM wires accordingly. A suitable fuse MUST be installed on the BAT+ lead within 18" of the battery for protection of the vehicle’s electrical system. Fuse Rating When replacing the fuse, make sure new fuse is the correct type and amperage. Using an incorrect fuse could damage the amplifier. The ALB12 uses (1) 15 amp ATO style fuse. 6 Power/Ground Wire Size For optimum performance, use only 12 gauge wire or larger.

INSTALLATION Control Setup and Adjustment Input Signal Connections Low Level (RCA) Crossover Frequency Control Phase Control Low level (RCA) input signal is preferred for best performance. Typical trunk-mount installations require a 17-20 foot RCA cable. Most trucks and behind-seat applications require a 6-12 foot RCA cable. Using twisted pair construction RCA cables will minimize noise. The adjustable crossover is used to filter out frequencies above 40Hz ~ 160Hz.
