Ground Terminal – A proper ground is required for your amplifier to operate at peak performance. A short ground cable the same
diameter as the power cable should be used to attach the ground terminal directly to the chassis of the vehicle. Always remove paint,
dirt or debris to expose bare metal where the ground cable will be attached.
Remote Terminal – The amplifier can be turned on by applying 12 volts to this terminal. Typically this voltage is supplied by a wire from
the source unit marked "remote" or "power antenna".
(+12) Power Terminal - This is the main power input for the amplifier and must be connected directly to the positive terminal of the
vehicles battery for proper operation. Use caution when installing (+12) power cable in the vehicle. Avoid running this cable parallel
with RCA cables, antennas, or other sensitive equipment due to massive currents that can induce noise into the audio system. It is also
very important to have a tight, secure connection for maximum performance. MTX recommends using 50mm 2 power wire with the
MTX RFL4120 amplifier.
Fuses - When fuses blow, replace them with the same value. Never use a higher rated fuse !
Speaker Terminals - Connect speakers to these terminals. Observe speaker polarity throughout the system. Improper phase can result
in loss of bass response and/or poor overall sound quality.
Bridge Mode:
When bridging the amplifier, use the Ch1 positive terminal and the Ch2 negative terminal only.
When bridging the amplifier, use the Ch3 positive terminal and the Ch4 negative terminal only.
Warning : do not bridge the amplifier with an impedance lower than 4 ohm.
Installation & Mounting :
MTX recommends your new amplifier be installed by an Authorized MTX retailer. Any deviation from specified installation instructions
can cause serious damage to the amplifier, speakers and/or vehicles electrical system. Damage caused from improper installation is
NOT covered under warranty. Please verify all connections prior to system turn on !
1. Disconnect the vehicle's negative battery cable.
2. Determine the mounting place for your MTX amplifier. Keep in mind there should be sufficient air flow for proper cooling. Mark the
mounting holes from the amplifier to be drilled. Before drilling make sure all vehicle wires, gas lines, brake lines and gas tank are clear
and will not interfere with installation. Drill the desired holes and mount the MTX amplifier.
3. Install a positive (+) power cable from the vehicle's battery through the firewall using a grommet or firewall bushing to avoid cable
damage from sharp edges of the firewall. Run the cable through the interior of the vehicle and connect it to the amplifier's +BATT
terminal. Do Not connect to the battery at this time.
Note : Use only proper gauge wire for both positive and negative connections.
4. Install a circuit breaker or fuse within 20cm of the battery. This effectively lowers the risk of severe damage to you or your vehicle
in case of a short circuit or accident. Make sure the circuitbreaker is switched off or the fuse is taken out of the fuse holder untill all
connections are made. Now connect your positive power cable to the positive battery terminal of the battery.
5. Grounding - Locate a proper ground point on the vehicle's chassis and remove all paint, dirt or debris to reveal a bare metal surface.
Attach the ground wire to that contact point. Connect the opposite end of the ground wire to the GND terminal on the MTX amplifier.
