Installation
Preliminary Considerations:
• If you feel unsure about installing this system yourself, have it installed by a qualified technician.
• Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on any
vehicle.
• Aftermarket amplifiers will put an increased load on the vehicle’s battery and charging system, which can reduce battery and alternator life. It is strongly recom-
mended to upgrade your factory alternator and battery for optimum performance from your new audio system.
CAUTION: Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire and/or possible injury.
1. Choose a mounting location that will be secure and offer plenty of unobstructed space for proper cooling. Then plan the wire routing. Keep RCA cables close
together but isolated from the amplifier’s power cables and any high power auto accessories, especially electric motors. When feeding the wires through the fire
wall or any metal barrier, protect them with plastic or rubber grommets to prevent short circuits. Leave the wires long at this point to adjust for a precise fit at
a later time.
NOTE: Never run wires underneath the vehicle.
2. Prepare the power cable for attachment to the amplifier by stripping 1/2” of insulation from the end of the wire. Insert the bared wire into the B+ terminal and
tighten the setscrew to secure the cable in place.
3. Trim the power cable within 18” of the battery and strip1/2”of insulation from the end of the wire.
4. Strip 1/2” from the battery end of the power cable and crimp a large ring terminal to the cable. Use the ring terminal to connect to the battery positive terminal.
DO NOT install the fuse at this time.
NOTE: ALWAYS protect the battery and electrical system from damage with proper fusing.
5. Prepare the chassis ground by scraping any paint from the metal surface and thoroughly clean the area of all dirt and grease. Strip the end of the wire and
attach a ring connector. Fasten the cable to the chassis using a non-anodized screw and a star washer. Prepare the grounding cable for attachment to the amplifier
by stripping 1/2” of insulation from the other end of the wire. Insert the bared wire into the GND terminal and tighten the setscrew to secure the cable in place.
6. Prepare the REM turn-on wire for connection to the amplifier by stripping 1/2” of insulation from the wire end. Insert the bared wire into the REM terminal
and tighten the setscrew to secure the cable into place. Connect the other end of the REM wire to a switched 12-volt positive source.
NOTE: The switched voltage is usually taken from the source unit’s accessory/remote lead.
7. Securely mount the amplifier to the vehicle or amp rack. Remember: Think before you drill!
NOTE: Be careful not to mount the amplifier on cardboard or plastic panels.
8. Connect the source signal to the amplifier by plugging the RCA cables/high level inputs into the input jacks at the amplifier. Use only one input configuration.
Using both the RCA and High Level inputs will cause undesirable operation. When using a Master/Slave configuration (MD models only), select which amplifier
will be the master, then set the mode switch to Master and connect RCA cables to the input jacks. The Slave amplifier(s); set the mode switch to Slave and connect
RCA cables to the Slave in/out jacks from the Master’s Slave in/out jacks.
NOTE: When using High Level Inputs, if audible engine noise is present, connect the Black wire to chassis ground. If noise is still present, contact your local
authorized dealer or Lightning Audio customer service. When using a Master/Slave setup do not exceed more than two amplifiers. (MD models only)
9. Connect the speakers. Strip the speaker wires 1/2” and insert into the speaker terminal and tighten the setscrew to secure into place. Be sure to maintain
proper speaker polarity. DO NOT chassis ground any of the speaker leads as unstable operation may result.
NOTE: Mono amplifier speaker outputs (A & B) are wired in parallel internally.
10. Perform a final check of the completed system wiring to ensure that all connections are accurate. Check all power and ground connections for frayed wires
and loose connections. Complete the installation by installing the proper value fuse.
Operation
Adjusting Level: To adjust the level setting, turn the amplifier gain level to the lowest setting. Turn the source unit volume up until distortion is audible and then
slowly down until the distortion is inaudible (approximately ¾ volume position). Next, increase the amplifier level setting until once again distortion is audible
and then down slowly until the distortion is inaudible.
NOTE: Proper level setting is done by a trained professional utilizing an oscilloscope. For a more in depth setting procedure, contact Lightning Audio Technical
Support. In a Master/Slave setup ONLY adjustments made to the master amplifier will effect the output. (MD models only)
Adjusting Crossover: Select the appropriate position for the crossover filter switch. Turn the crossover adjustment knob to the lowest setting. With the system
playing at normal listening level, turn the crossover adjustment knob up slowly until the desired crossover point is achieved. Example: subwoofers- low pass with
an 80Hz crossover point and full-range- high pass with a 100Hz crossover point
NOTE: Some models include a subsonic filter with a variable 15-40Hz high pass filter designed to prevent frequencies below the audio range from being applied
to the subwoofer from the amplifier. Set this to your personal preference while listening to the system. In a Master/Slave setup ONLY adjustments made to the
master amplifier will effect the output. (MD models only)
