INSTALLATION

Disconnect the ground at the vehicle battery before proceeding.

1. Connect the amplifier to the battery

For maximum amplifier performance, we suggest 4 gauge wire and a 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 or Circuit City.

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 the source unit does not provide a remote output, connect to a switched 12-volt source, e.g. ignition switch.

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 will be attache (NO FACTORY BOLTS). Connect the ground cable to the amplifier at this point.

- NOTE -

For optimum performance and sound reproduction, prepare and secure the ground properly. Remove any surface material before securing to your chassis, ensuring a metal-to-metal ground point.
