Installation

Installation Considerations

  1. Be sure to carefully read and understand the instructions before attempting to install the unit.
  2. For safety, disconnect the negative lead from the battery prior to beginning the installation.
  3. For easier assembly, we suggest you run all wires prior to mounting your unit in place.
  4. Route all of the RCA cables close together and away from any high current wires.
  5. Use high quality connectors for a reliable installation and to minimize signal or power loss
  6. 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.
  7. Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best protection.
  8. Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any wires routed through metal, especially the firewall.
  9. ALWAYS protect the battery and electrical system from damage with proper fusing. Install the appropriate fuse holder and fuse on the +12V power wire within 18” (45.7 cm) of the battery terminal.
  10. When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure a good, clean ground connection. Grounding connections should be as short as possible and always be connected to metal that is welded to the main body, or chassis, of the vehicle. Seatbelt bolts should never be used for connecting to ground.

Wiring the System

  1. 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. This is done to prevent coupling the noise from radiated electrical fields into the audio signal. When feeding the wires through the firewall 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.
  2. Prepare the RED wire (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 set screw to secure the cable in place
  3. Trim the RED wire (power cable) within 18” of the battery and splice in a inline fuse holder (not supplied). See Specifications for the rating of the fuse to be used. DO NOT install the fuse at this time.
  4. Strip 1/2” from the battery end of the power cable and crimp an appropriate size ring terminal to the cable. Use the ring terminal to connect to the battery positive terminal.
  5. Prepare the BLACK wire (Ground cable) for attachment to the amplifier by stripping 1/2” of insulation from the end of the wire. Insert the bare wire into the GROUND terminal and tighten the set screw to secure the cable in place. Prepare the chassis ground by scraping any paint from the metal surface and thoroughly clean the area of all dirt and grease. Strip the other end of the wire and attach a ring connector. Fasten the cable to the chassis using a non-anodized screw and a star washer.
  6. Prepare the Remote turn-on wire for attachment to the amplifier by stripping 1/2” of insulation from the end of the wire. Insert the bared wire into the REMOTE terminal and tighten the set screw to secure the wire in place. Connect the other end of the Remote wire to a switched 12 volt positive source. The switched voltage is usually taken from the source unit’s remote amp on lead. If the source unit does not have this output available, the recommended solution is to wire a mechanical switch in line with a 12 volt source to activate the amplifier.
  7. Securely mount the amplifier to the vehicle or amp rack. Be careful not to mount the amplifier on cardboard or plastic panels. Doing so may enable the screws to pull out from the panel due to road vibration or sudden vehicle stops.
  8. Connect from source signal by plugging the RCA cables into the input jacks at the amplifier
  9. Connect the speakers. Strip the speaker wires 1/2” and insert into the speaker terminal and tighten the set screw 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.
  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 which could cause problems. Install inline fuse near battery connection.

Troubleshooting

NOTE: If you are having problems after installation follow the Troubleshooting procedures below.

Check Amplifier for proper connections. Verify that POWER light is on. If POWER light is on skip to Step 3, if not continue.

  1. Check in-line fuse on battery positive cable. Replace if necessary.
  2. Check fuse(s) on amplifier. Replace if necessary.
  3. Verify that Ground connection is connected to clean metal on the vehicle’s chassis. Repair/replace if necessary.
  4. Verify there is 9 to 14.4 Volts present at the positive battery and remote turn-on cable. Verify quality connections for both cables at amplifier, stereo, and battery/fuseholder. Repair/replace if necessary

Protect light is on.

  1. If the Protect light is on, this is a sign of a possible short in the speaker connections. Check for proper speaker connections and use a volt/ohm meter to check for possible shorts in the speaker wiring. Too low of a speaker impedance may also cause Protect to light.

Check Amplifier for audio output.

  1. Verify good RCA input connections at stereo and amplifier. Check entire length of cables for kinks, splices, etc. Test RCA inputs for AC volts with stereo on. Repair/replace if necessary.
  2. Disconnect RCA input from amplifier. Connect RCA input from test stereo directly to amplifier input.

Check Amplifier if you experience Turn-on Pop.

  1. Disconnect input signal to amplifier and turn amplifier on and off.
  2. If the noise is eliminated, connect the REMOTE lead of amplifier to source unit with a delay turn-on module.

OR

  1. Use a different 12 Volt source for REMOTE lead of amplifier.

Check Amplifier if you experience excess Engine Noise.

  1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.

OR

  1. Bypass any and all electrical components between the stereo and the amplifier(s). Connect stereo directly to input of amplifier. If noise goes away the unit being bypassed is the cause of the noise.

OR

  1. Remove existing ground wires for all electrical components. Reground wires to different locations. Verify that grounding location is clean, shiny metal free of paint, rust etc.

OR

  1. Add secondary ground cable from negative battery terminal to the chassis metal or engine block of vehicle.

OR

  1. Have alternator and battery load tested by your mechanic. Verify good working order of vehicle electrical system including distributor, spark plugs, spark plug wires, voltage regulator etc.
