Before beginning any installation, follow these simple rules:
- Be sure to carefully read and understand the instructions before attempting to install the unit.
- For safety, disconnect the negative lead from the battery prior to beginning the installation.
- For easier assembly, we suggest you run all wires prior to mounting your unit in place.
- Route all of the RCA cables close together and away from any high current wires.
- Use high quality connectors for a reliable installation and to minimize signal or power loss.
- 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.
- Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best protection.
- Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any wires routed through metal, especially the firewall.
- 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.
- 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.
BATTERY AND CHARGING
- Amplifiers will put an increased load on the vehicle's battery and charging system.We recommend checking your alternator and battery condition to ensure that the electrical system has enough capacity to handle the increased load of your stereo system. Stock electrical systems which are in good condition should be able to handle the extra load of any Punch Series amplifier without problems, although battery and alternator life can be reduced slightly.To maximize the performance of your amplifier, we suggest the use of a heavy duty battery and an energy storage capacitor.
Procedure 1: Check Amplifier for proper connections.
- Check in-line fuse on battery positive cable. Replace if necessary.
- Verify that Ground connection is connected to clean metal on the vehicle’s chassis. Repair/replace if necessary.
- Verify there is 9 to 16 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.
Procedure 2: Protect light is on.
- This is a sign of a possible short in the speaker connections. Check for proper speaker connections and use an ohm meter to check for possible shorts in the speaker wiring.Too low of a speaker impedance may also cause Protect to light.
- In the event that the speaker connections are not the issue, check for proper speaker impedance and rewire if needed.This can also be a sign of driving the amplifier at very high power levels without adequate airflow around the amplifier. Shut off the system and allow amplifier to cool. Check that the vehicle charging system is maintaining proper voltage. If the previous items do not solve the problem, a fault may be in the amplifier, call customer service for support.
Procedure 3: Check Amplifier for audio output.
- Verify good RCA/Speaker input connections at stereo and amplifier. Check entire length of cables for kinks, splices, etc.Test RCA/Speaker inputs for AC volts with stereo on. Repair/replace if necessary.
- Disconnect RCA/Speaker input from amplifier. Connect RCA/Speaker input from test stereo directly to amplifier input.
Procedure 4: Check Amplifier if you experience Turn-on Pop.
- Disconnect input signal to amplifier and turn amplifier on and off.
- If the noise is eliminated, connect the REMOTE lead of amplifier to source unit with a delay turn-on module.
Procedure 5: Check Amplifier if you experience excess Engine Noise.
- Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.
- 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.
- 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.
- Add secondary ground cable from negative battery terminal to the chassis metal or engine block of vehicle.
- 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.
