INSTALLATION

Disconnect the ground at the vehicle battery before proceeding.

1. Connect the amplifier to the battery

For maximum amplifier performance, we suggest StreetWires 4 gauge wire and 1 Farad stiffening capacitor. A fuse or circuit breaker is required at maximum distance of 18” from the battery to protect the battery, the vehicle, and more importantly you (see attached chart for proper fuse ratings). It is highly recommended that installation be carried out by an authorized MTX dealer.

2. Connect the amplifier remote turn-on

Connect the remote input terminal of the amplifier to the remote output terminal of the source unit (only if using RCA inputs) to establish amplifier remote on/off through the power on/off of the source unit. If a source unit is being used without RCA outputs, use the high-level inputs for signal which will turn the amplifier on via our Smart Engage circuitry (Four-channel amps will only engage on the front high-level inputs).

3. Connect the amplifier ground to the vehicle chassis

For maximum amplifier performance we suggest 4 gauge wire. Find a solid piece of metal and scrape the paint away where the ground cable will be attached (DO NOT CONNECT THE GROUND CABLE TO FACTORY BOLTS). Connect the ground cable to the amplifier at this point.

- NOTE -

For optimum performance and sound reproduction, prepare and secure the ground cable properly.

Remove any surface material before securing to your chassis, ensuring a metal- to-metal ground point.

4. Remote Gain Control

Included is a remote gain control, which is a volume control that is active with the low pass filter engaged. This control should be mounted near the driver in an easily accessed location. This is not a gain knob, this is a level control. The level control will attenuate the amp or increase its output to the level of the gain setting. It is used to adjust bass output between music sources or tracks (see the picture below for connection location).

5. Connecting signal cables to the amplifier

There are two ways to supply the signal to our amplifiers. High level (speaker level) or line level (RCA)To get maximum performance, we suggest connecting a high quality RCA to the corresponding outputs at the source unit and inputs of the amplifier.

6. Reconnect the battery ground to the vehicle battery

Double check all the previous installation steps. Make certain the wiring and component connections are securely attached to the amp +BATT, remote and ground. If everything is in order, complete the installation by reconnecting the battery ground to the vehicle battery.

Located on the Input Panel, the objective of input GAIN adjustment is to match the output of the source unit with the input of the amplifier. The output voltage of individual source units can vary. Some source units have an output of 200mV and others have 5 volts or more. To cater to these variations, the amplifier has an adjustable gain level that ranges from 100mV to 5 volts. Follow steps below to set gains.

Besides better sonic reproduction, proper input gain also helps to prolong the reliability span of your amplifier by eliminating excessive internal temperature generated by incompatible source unit output and amplifier input.

Note: Turning the input gain up does not indicate more power. Just more noise. The input gain control is not a power control.

If the Remote Gain is used, connect the plug of the Remote Gain to the port on the panel of the amplifier.

1.Turn the input GAIN all the way down (counter-clockwise).

2.Set the volume control of the source unit to approximately 3/4 of its maximum output.

3.Turn the balance control of the source unit to its center position (flat).

4.Leave the tone (bass/treble) controls at their usual position.

5.Play a CD or tape track with great dynamic range.

6.Use the Bass Boost Control on the amp to enhance the bass performance (if desired), not the bass on the headunit. Use this control sparingly.

7.To locate the optimum gain setting, ask the person assisting you to turn the input GAIN control clockwise until audio distortion starts to develop. Turn the gain control back wards slightly to minimize the distortion.

8.If you constantly switch between CD/tape and radio, you will need further adjustment since radio output level differs from that of CD or tape. In this case, you need to locate a balanced Gain setting which is best for both the output level of radio and the CD/tape.

Note: If you are using the Remote Gain, make sure to take this into account during setup procedures of the subwoofer amplifier. You should set the system up with the Remote Gain plugged in and with the level knob turned all the way down (counter-clockwise). The Remote Gain only works when you’ve selected the LP (low-pass) crossover configuration. On fourchannel amplifiers, the Remote Gain only affects the rear channels.

CROSSOVER SELECTION

The amplifier has built-in high-pass/low-pass filters that can be bypassed by sliding the switch to the full range (FR) position. The crossover micro switch can be found directly above the FREQ adjustment.

1.When the high-pass is selected (HP), the amplifier will be devoted to mid/tweeters.

2.When the low-pass is selected (LP), the amplifier will be used to drive woofers/subwoofers. With this setting, the Remote Gain can directly control the amplifier playback level.

3.When the full range is selected (FR), the amplifier is used as a full range amplifier.

CROSSOVER FREQUENCY SELECTION (FREQ)

Both the high-pass and the low-pass section offer continuously adjustable crossover frequencies between 40Hz and 350Hz. Adjust the setting according to your speaker component specification or to your particular preference.

BASS BOOST CONTROL (BASS BOOST)

Select a boost level between 0dB and +18dB @ 40Hz to enhance the bass performance for your sound system. BASS BOOST is NOT free! Every 3dB of boost costs you twice as much in power. Make sure to set the final gains after setting the Bass Boost to work best with your subwoofer/enclosure combination. More is not always better!
