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 con- nections 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.
