Wiring

1. Ground cable (black)
2. Remote turn-on cable (blue)
3. Power Cable (+12Vred)
4. Channel 1 speaker output cables: negative (white w/black stripe) and positive (white).
5. Channel 2 speaker output cables: negative (grey w/black stripe) and positive (grey).\
6. Channel 1 (White) and Channel 2 (Red) RCA Inputs
   

Power Connections

1. Make sure to disconnect the NEGATIVE(-) terminal from your vehicle’s
2. Attach a 10-gauge or heavier wire to the black cable from the harness marked The connection should be as close to the amp as possible). The wire should terminate in a ring connector. Connect the ring connector to a metal part of the vehicle’s chassis, making sure that there is no paint or other insulator blocking a good ground connection. If needed, you can connect to the battery’s negative terminal.
3. Attach a 10-gauge or heavier wire to the red cable from the harness marked +12V to the battery’s POSITIVE(+) terminal. The power wire should terminate in a ring terminal connected directly to the POSITIVE (+) terminal.
4. Connect the blue remote wire to the head unit’s remote output using 18-gauge or heavier This connection is responsible for turning the amplifier on and off with the rest of the system. Should your head unit not have any turn-on leads, you can wire the remote terminal to an accessory lead, which turns the amplifier on with your vehicle’s ignition.

Please note, it is a good practice to feel the power and ground wires near the amplifier after using the amp for a while. If the wires feel hot to the touch, you probably have a bad or loose connection. If after adjusting your connections the wires still feel hot, you should upgrade to the next heaviest gauge wire. As connections can work loose due to vehicle vibrations, we recommend periodically tightening all power and ground connections

Input configurations

2-Channel Input

If your head unit has a single pair of RCA jacks, feed their output to the amplifier’s Channel 1 and 2 input jacks.

Output Configurations

2-Channel Mode

Install any combination of of component or coaxial speakers

independently on channels 1 – 2, being careful not to load any single channel below 2-ohm. For typical 6″ x 9″ or 6.5″ or component or coaxial speaker installs, set the Crossover Mode Switches to full range (OFF) (a).
2-Channel Bridged Mode (when using a subwoofer)

Channels 1-2 should be bridged as per the diagram. Wire the woofer to Channel 1 ‘s positive (+) tenninal and Channel 2’s negative ( – ) tenninal. Set the crossover switch to LPF.

Adjusting the System

1. Use a small Phillips head screw driver to remove the 6 screws securing the plate located on the side of the amplifier (a). Using the included panel removal tool, carefully remove the plate to access the control panel (b). Once you are done making your adjustments, replace the plate. Make sure that it is seated properly and the screws are replaced properly. Failure to do so may result in damage to the amplifier as water or other debris may get through.
   

2. Once the system is operational, set all crossover points to the approximate settings. In the case of a basic subwoofer system, set the Low Pass Filter (LPF) crossover at 100Hz or so. Turn the controls using a small flathead screwdriver. Do not apply any pressure while turning as this might break the control unit.

3. Set the amplifier’s Input Sensitivity using the control accessible on the side of the amplifier marked LEVEL (gain). Turn it counterclockwise to the MIN position. Adjust your head unit’s volume gain to the maximum it can go before signal distorts or to the loudest gain, which is usually about 75% – 85% on most head units (you can also use an oscilloscope to see at what gain level your head unit distorts). When you begin to hear distortion, back down one notch. Now turn the LEVEL control on the amp clockwise until you hear distortion, then turn it counterclockwise by a notch or until the distortion is gone. The amp’s input sensitivity is now set. It is helpful to have a second person to help you set the gain. When setting up a multi-amp system, set each amplifier’s level controls separately. Start off with the bass amplifier, then adjust the highs amplifier’s level control to match. Please note that the level control of any vessel’s amplifier should not be mistaken for a volume control. It is a sophisticated device designed to match the output level of your source unit to the input level of the amplifier. Do not adjust the amplifier level to maximum unless your input level requires it. Your system can also be extremely sensitive to noise when the input level is set to maximum and does not match your input signal. These adjustments need to be made only once when first setting up the system.

4. Once you are satisfied with the level control settings, use any equalizer controls to adjust the system’s tonal level for personal preference. Keep in mind that after equalizing you may have to go back and reset the amplifier’s level controls.

If your unit has been professionally installed please do not change the gain settings set by the installer, he or she is the professional!

Features

Input Voltage Switch
This switch allows you to set the voltage sensitivity to match the input source. For example, if you are using a head unit with pre outs, you set the switch on the amp to low (a). If you are using a factory radio, use the included adapters to wire the amp’s RCA inputs to the factory speaker outputs. Then set the switch to high (b) so that all input goes to the RCA jacks.

Bluetooth
When the unit powers up, the BT LED indicator (located on the right side of harness) will begin to flash indicating that it is in pairing mode. Look for and select A1V220 from your device’s list of the list of available Bluetooth devices. If pairing is successful, the LED indicator will remain solid blue. Please note, a BT connection will overide RCA input. If you wish to return to RCA input, you will need to end the connection via your device.
Power/Protect LED
This model features one LED (located on the left side of the harness) that provides indication of the amplifier’s status. The LED will light green when the amplifier is receiving proper power, ground, and remote voltages. In case the amplifier encounters a diagnostic condition as listed below, the LED will light red indicating a diagnostic condition.

• When a diagnostic condition is sensed, the amplifier will then turn into self-preservation mode and if the cause of the diagnostic condition is not corrected will eventually shut down.
• Thermal Protection: When the amplifier reaches an unsafe operating temperature of 80 degrees Celsius, the amplifier will turn off. Once the amplifier cools down to a safe temperature, it will automatically turn on again. If you live in a hot climate, we suggest installing additional cooling fans to exhaust the hot air which can build up in the trunk. This will help keep the ambient temperature in the trunk as low as possible so that your amps work flawlessly and without any musical interruption.
• Speaker Short Circuit Protection: Should your speakers short circuit due to voice coil burn out, or should the amplifier sense an impedance too low to handle, the protection LED will light red, indicating a diagnostic condition. Turn off your system, disconnect one speaker at a time, and try to determine which speaker might be faulty. Correct the condition and restart the amplifier. You must reset the amplifier by turning it OFF and then ON again by the Remote power connection after correcting a diagnostic condition. (furn your radio off and then on again.)
• Input Overload Protection: This circuit will either shut down the amplifier completely or make the amplifier spurt on and off indicating that it is in a diagnostic condition. Turn the system off and reduce the gain on the amplifier or volume from your head unit. This should result in a corrected condition.
• DC Offset Protection: Should any DC voltage try to enter the amplifier via the speaker terminals it will cause the amplifier to shut down and not operate until this condition is remedied. This circuit will also protect damaging high DC voltages from reaching your speakers should your amplifier ever malfunction.

PLEASE NOTE : You must reset the amplifier by turning it OFF and then ON again after correcting a diagnostic condition (turn your radio off and then on again). If the amplifier stays in protection after a reset, it is most likely faulty.
Please note, when powering up/down or when switching between Bluetooth and RCA input, the power/protect LED will be solid red. This feature serves to protect the amp and is perfectly normal.
