FEATURES • EXCLUSIVE INFINITE CROSSOVER DESIGN • PARALLEL INPUT SWITCH • ASYMMETRICAL ELECTRONIC CROSSOVER DESIGN For a source unit having a single pair of signal outputs an adapter is needed to split the source signal for the front and rear inputs. With the mobile electronic crossover, by engaging the parallel input feature, an external adapter is no longer necessary.
CONTROLS, INDICATORS, and TERMINALS CXR-7 5
1. POWER INPUT TERMINAL (RED) This wire should be connected to the positive terminal of your vehicle battery or other constant +12V source. 2. GROUND INPUT TERMINAL (BLACK) This wire should be connected the vehicle’s chassis. Ensure that you have a good connection. When connecting the wire make sure that there is no paint or other insulator blocking the connection. 3. REMOTE TURN ON INPUT TERMINAL (ORANGE) This wire should be connected to the remote turn on wire or antenna lead of the source unit.
CONTROLS, INDICATORS, and TERMINALS 11. FRONT CHANNEL HIGH-PASS FREQUENCY MULTIPLIER 17. LEFT/RIGHT FRONT CHANNEL OUTPUT TERMINALS Positioning this switch at the “x20” position changes the range of selectable crossover frequency for the front channel high-pass from 25Hz - 400Hz to 500Hz - 8K Hz. Connect to the front channel amplifier left/right inputs. 12. SUBWOOFER FREQUENCY SELECTOR Allows you to set the low-pass crossover frequency for the subwoofer channel between 25Hz and 400Hz. 13.

FINAL SYSTEM CHECK 1. Pre-Setting A. Set front, rear and subwoofer amplifier input gain to half of their maximum. B. Preset the crossover frequencies and output levels as follows.
TROUBLE SHOOTING GUIDE SYMPTOM PROBABLE CAUSE 1. No power. • Check all the ground, B+ and remote terminals for tight connection. • Check all fuses. • Use a volt/ohm meter to check all power wire connected to see if the system is receiving +12V. 2. “Motorboating”: the unit power indicator going off repeatedly when the audio system is on. • Check if the unit B+ power input is connected to directly to a +12V power source. • Check the battery voltage. If low, recharge or replace it.
