Installation & Mounting : Installation examples :
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 vehicle’s 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 (12V) 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 circuit breaker 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.
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 dedicated
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 the MTX amplifier’s speaker terminals using proper gauge wire.
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.
Troubleshooting :
Problem Cause Solution
Power LED is off No +12V at remote connection 12V to terminal
No +12V at Power connection 12V to terminal
Insufficient ground connection Verify ground connection
Blown power fuse Replace fuse and try to understand why
Blown amp Return for service
3 LEDs are flashing red Speaker load is too low Remove the speaker(s)
The amp is in thermal protection Wait for the amp to cool down
Input tension is too high or too low Check your battery and your alternator
3 LEDs are solid red, Volume on head unit off Increase volume on head unit
but no output Speaker connections not made Make speaker connections
Gain control on amplifier set to minimum Turn up gain
Signal processing units off Apply power to signal processor
All speakers blown Replace speakers
Output distorted Head unit volume set too high Lower head unit volume
Amplifier gain set too high Lower amplifier gain
Balance reversed Speakers wired reversed Wire speakers with correct orientation
RCA inputs reversed Reverse RCA input
Bass is weak Speakers wired out of phase Wire speakers with correct phase
Not using MTX woofers Buy MTX woofers
Blowing fuses Excessive output levels Lower the volume
Amplifier defective Return for service
