INSTALLATIONS

CAUTIONS
Please follow all the installation recommendations and instructions in this manual, Installing and using the electronic crossover in methods other than those outlined herein may reduce the performance capability of the crossover. Any such installation or usage may render the product warranty void.

LOCATION

  1. Select a mounting location that is easily and conveniently accessible, e.g. inside the trunk.
  2. To avoid damage to the crossover, keep the crossover away from any heat source (such as the engine or any heat-generating ducts).
  3. There should be adequate clearance above the crossover to allow easy adjustment.

WIRING LAYOUT
Once the location of all the components has been determined, plan the best routes for all the necessary wiring, making sure that the wires are easily accessible without dismounting the various components.

CAUTIONS
Routing audio cables and power cables together would invariably cause radiated engine noise in your audio system. If possible, run audio cables on one side of your car and power cables on the other. Never route these wires underneath the vehicle body.

  1. Check and make sure the vehicle’s main battery and/or auxiliary battery, if any, is/are in good working condition and has sufficient capacity to run the electrical components of the vehicle plus the complete audio system.
  2. The crossover is designed for use in a 12-volt NEGATIVE GROUND electrical system ONLY. Installing the crossover in a vehicle with a positive ground electrical system could result in serious damage to the electronic crossover, other audio components, and/or the vehicle’s electrical components.
  3. FOR SAFETY, DISCONNECT THE BATTERY GROUND BEFORE INSTALLATION.

MOUNTING

  1. Place the crossover at the desired location and use it as a template to determine the exact position of the mounting holes. Mark the mounting holes with a pen.
  2. Use a center punch to ensure drilling the exact position for the screws. Drill four (4) 1/8 pilot holes. DO NOT BEGIN DRILLING UNTIL YOU HAVE PUT THE CROSSOVER ASIDE. USING THE CROSSOVER AS A DRILLING GUIDE MAY CAUSE IRREPARABLE DAMAGE TO THE CROSSOVER.
  3. Mount the unit with the Philips head sheet metal screws and steel washers provided.

WIRING

  1. Run the various wires according to your wiring layout, avoiding sharp edges and door jams.
  2. Electrical tape or grommets should be used to protect the wires when they are routed through bare metal holes.

Note
The battery ground should remain DISCONNECTED at all stages of installation.

CONNECTIONS

  1. Connect the crossover to the Source Unit Connect the outputs of the source unit to the inputs of the crossover (either via the low-impedance input or the high-impedance input).
  2. Connect the crossover to the Amplifiers Connect the high-pass and low-pass outputs of the crossover to the inputs of their respective amplifiers.
  3. Connect the Amplifiers to the Speakers Connect the various amplifiers to their speakers following the amplifier’s manual and specifications.
  4. Connect the crossover to the Battery Connect the power input cable to the positive terminal of the battery. Add a circuit breaker to any power wire that runs through a firewall or sheet metal to protect the battery, the vehicle, and more importantly, you.
  5. Ground Connection Connect the ground input cable of the crossover to the vehicle chassis. For better conductivity. If necessary, scrape the paint off the chassis to reveal bare metal at the contact point.
  6. Connect the Remote Input Terminal of the crossover to the Source Unit Connect the remote input cable of the crossover to the remote output terminal of the source unit to establish crossover remote power on/off via the source unit. If the source unit does not provide a remote output, connect to its power antenna terminal or other switched 12-volt source, e.g. Ignition switch.
  7. Reconnect the Battery Ground to the Vehicle Chassis Double-check all the previous installation steps with the following table. If everything is in order, complete the installation by reconnecting the battery ground to the vehicle chassis.

Installation

System Check

PRELIMINARY ADJUSTMENT

Pre Setting

  • Preset high-pass and low-pass amplifier input gain to half of their maximum.
  • Preset the crossover frequencies and output levels as follows: High-Pass Frequency Selector: 125 Hz Low-Pass Frequency Selector: 100 Hz High-Pass Output Level: 10 o’clock position Low-Pass Output Level: 10 o’clock position
  • Preset the volume of the source unit to its minimum (otherwise, when the source unit is turned on, the sudden surge of high power from the amplifiers might cause damage to the audio components).

Turn the source unit on and slowly turn the source unit volume up

  • No Sound At All
    • Turn the system off immediately.
    • Check if connections are made properly (refer to the sub-section titled CONNECTION for details).
    • Use a Volt/Ohm meter to make sure good chassis ground is established for
      each component that needs to be grounded.
    • Check if the power input of all system components is properly connected
      to 12-volt positive power supply.
    • Check if the remote on/off terminal of all system components is properly connected to a positive 12-volt source.
    • If everything is in order, turn the power on again. If the problem persists, refer to the section titled TROUBLESHOOTING for assistance.
  • Obvious Distortion Turn the system off and refer to the section titled TROUBLESHOOTING for assistance.
  • Out-of-Phase Problem (Abnormal Bass) Turn the system off and refer to the section titled TROUBLESHOOTING for assistance. If none of the above problems exists, proceed to the next step.

CROSSOVER FREQUENCY ADJUSTMENT
When setting the crossover frequencies, it is best to use compact discs or cassette tapes with greater dynamic range. Usually, home-recorded tapes are better in this respect than commercially recorded tapes.

System Check

  1. Center the tone, balance, and fader controls of the source unit (leaving the other controls at their previous positions).
  2. Set the volume of the source unit to approximately 2/3 of its maximum output.
  3. Low-Pass Crossover Frequency Setting: Starting from 100 Hz, listen to the bass sound quality, if the bass is “Boomy” or soft sounding, select the low-pass frequency to other positions (80/63/50 Hz) until the bass sounds tight and deep. It is all a matter of personal preference. The optimum setting varies from vehicle to vehicle and from individual to individual. A subwoofer crossover frequency setting of as low as 80Hz is not uncommon.
  4. High-Pass Crossover Frequency Setting: Starting from 125Hz, adjust the high-pass frequency until you get your desired sound quality. Again, there is no universal optimum setting. It depends on the size and location of the front speakers and also your personal preference.

NOISE CHECK
Before mounting the crossover and the other audio components permanently, please conduct the following noise check:

  1. Start the engine and turn on the power of the source unit.
  2. Rev the engine and vary the audio volume to check for radiated engine noise. If there is an alternator whining noise or tic-tic noise, refer to the TROUBLESHOOTING for assistance.
  3. If no unwanted noise is detected, double-check all the wiring and cables for safe placement. Then securely tighten the mounting screws of all the audio components.
