CAUTION
Always consider consulting a professional audio installer before installing any audio components. Be careful and take your time. Do not let wires make contact with metal edges or hot engine components.

Mounting and Hardware

Prior to mounting, connect the wires to ensure proper operation.
MOUNTING

1. Select the desired mounting location, either under the dash or in the dash. Make sure that there is adequate depth for the HF7BEQ.
2. Use the mounting brackets and hardware provided. Make sure there is proper clearance for the mounting bracket screws when attaching under the dash. Use caution to ensure there are no wiring harnesses behind the dash panel (where the mounting screws are fastened).
3. Route the power, ground, and remote wires away from moving parts to prevent pinching or shortened wires.

WIRING

1. Power Wire: The power wire should connect to a constant or switched +12 volt source with a (2 Amp) in-line fuse. We recommend that you use the radio constant or switch +12 volt source.
2. Gound Wire: Connect the ground wire to a clean chassis ground point. Be sure to remove all paint and primer to expose the clean metal. Use a ring terminal and lock or star washer to secure the ground wire.
3. Remote Wire: The remote wire should be connected to the source until remote or antenna wire provides +12 volts when the source unit is “on” and 0 volts when the source unit is turned “off.”

Functions & Operations

1. Volume Control: The audio level (volume) can be increased or decreased with this illuminated VOLUME control knob.
2. Fader Control: This allows to control of the front and rear output levels.
3. Subwoofer Control: The Subwoofer output level is controlled by the SUB illuminated knob.
4. Equalization: Seven bands (50Hz, 125Hz, 315Hz, 750Hz, 2.2kHz, 6kHz,& 16kHz) each frequency adjustable +/- 12dB
5. LED Selection: Turn on/off front illumination
6. Subwoofer Frequency Switch: This switch allows you to choose between three different frequency settings (60Hz, 80Hz, 120Hz)
7. Input Selection: Allows to select input CD (RCA Input), High-Level Input, AUX
8. Input Level (Gain) Control (CD Input Only): This input level control can be adjusted to match the source unit line-level sensitivity.
9. AUX: 3.5mm jack connected to (Phone/MP3 player) have L & R unbalanced inputs which are directly routed to the internal EQ and passed through to the outputs. Each input can be chosen independently by the input selector switch.
10. High-Level Input: Speaker Level
11. CD (RCA Input): Input from the source unit (radio/CD player) has L & R unbalanced inputs which are directly routed to the internal EQ and passed through outputs. Each input can be chosen independently by the input selector switch.
12. Subwoofer Outputs : The subwoofer left & right are low pass outputs are connected to the subwoofer amplifier(s) inputs.
13. Rear Outputs: This is a high pass output to be connected to the amplifier(s) inputs for rear speakers.
14. Front Outputs: This is a high pass output to be connected to the amplifier(s) inputs for front speakers.
15. Power Connectors: This is the input jack that supplies power, ground, and remote.

The 12+ Volt Terminal Connects to either constant +12 volts or to an accessory switched +12 volt source. The radio power wire is the preferred source. (This is a
fused power wire).
The Ground Terminal Connect to the chassis ground.
The Remote Terminal Connect to the source unit remote or antenna output wire that provides +12 volts when the source unit is “on” and 0 volts when the source unit is turned “off.”

Diagnostics & Trouble Shooting

The key to finding the problem in a troubled sound system is to isolate parts of that system in a logical fashion to track down the fault and correct the issue. The diagnostic system will not shut down the crossover or the amplifier(s), although the amplifier(s) own protection circuitry may shut the amplifier(s) down, should a fault status occur. You will need to consult the owners manual for that particular amplifier

Low Output Power

1. Check that level controls have been set up properly.
2. Make sure that the battery voltage, as measured at the amplifier(s) and crossover +12 volt and ground terminals, is 11 volts or more.
3. Check all +12 volt and ground connections.

Fuses Blowing

1. Ensure that the voltage to the unit does not exceed 15 volts.
2. A short on the main +12 volt cable from the battery to the vehicle chassis will cause the main fuse to blow.
3. If the HF7BEQ is blowing fuses continually with only +12 volt, ground, and remote lead connected, the unit may be faulty.

Fuses Blowing

1. Check all fuses.
2. Check all connections.
3. Measure the +12 volt and remote turn-on voltages at the amplifier(s) and crossover terminals. If these are nonexistent or low, take voltage measurements at fuse holders, distribution blocks, the head unit’s +12 volt, and remote leads to localize the problem.

Hiss, or White Noise

1. High levels of white noise usually occur when level controls are turned up too high – reduce the levels until the noise is no longer present.
2. Another problem that can cause excessive hiss, is a noisy head unit – unplug the crossover input RCA’s, and if the hiss level reduces, the source unit is at fault.

Electrical Interference
The inside of an automobile is a very hostile electrical environment. The multitude of electrical systems, such as the ignition system, alternator, fuel pumps, and air conditioners, create radiated electrical fields, as well as noise on the +12 volt supply and ground. To try and eliminate this noise, run a wire from the radio ground wire to the ground input on the equalizer.

Ticking or Whine that changes with engine RPM

1.  This problem could be caused by the radiation pickup of RCA cables that are too close to a fuel pump or a distributor.
2. Check that the head unit ground is connected straight to the vehicle chassis and does not use factory wiring for the ground.
3. Try to supply the head unit with a clean +12 volt supply directly from the battery +, instead of using a supply from the in-dash wiring/fusebox.

Constant Whine
This type of noise can be more difficult to pinpoint but is usually caused by some kind of instability, causing oscillations in the system.

1. Check all connections, (especially for good grounds).
2. Make sure that no speaker leads are shorting to the exposed metal on the vehicle chassis.
3. RCA cables are notorious for their problematic nature, so check that these are good, especially the shield connections.
