MTX Audio MXA4002 - Manual (Page 4)

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.
