Installation & Mounting :
6. Connect a Remote Turn-on wire from the head unit to the MTX amplifier’s Remote terminal. If the head unit does not have a dedi-
cated Remote Turn-on lead, you may connect to the head unit’s Power Antenna lead.
7. Connect RCA cables from the head unit to the MTX amplifier’s RCA inputs. Run all signal cables away from vehicle wiring, computers
and power cables. If cables must be crossed do so at a 90° angle. Use only high quality RCA cables to decrease radiated noise from
entering the system.
8. Connect your speakers to your MTX amplifier’s speaker terminals using the right gauge speaker wire. Two channels bridged can drive
a 4 ohm minimum load for max power.
9. Double check all previous installation steps, in particular, wiring and component connections. Once verified, reconnect the vehicle’s
negative battery cable, turn the circuit breaker on or place the fuse in the fuse holder.
Note
: Gain Levels on the amplifier should be turned all the way down (counter clockwise) before proceeding with adjustments.
