IMPORTANT NOTICE
Whenever working on the vehicle, it is recommended to disconnect the battery
prior to starting work. Failure to do so may lead to a risk of electric shock
or equipment damage.
When connecting power and ground wires ensure that the red power wire is fused at the point ;; where it is connected to the vehicle’s battery. Failure to do so can result in damage to the vehicle if a short circuit develops between the vehicle connection point and the product.

INSTALLATION AND MOUNTING
MTX recommends your new TERMINATOR 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 !
- Disconnect the vehicle’s negative battery cable.
- 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.
- 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.
- 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 until all connections are made. Now connect your positive power cable to the positive battery terminal of the battery.
- 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.
- Connect a Remote Turn-on wire from the source unit to the MTX amplifier’s (REM) terminal. If the source unit does not have a dedicated Remote Turn-on lead, you may connect to the source unit’s Power Antenna lead.
- Connecting signal cables to the amplifier – There are two ways to supply the signal to your amp.
- To get maximum performance, we suggest connecting a high quality RCA to the corresponding outputs at the source unit and inputs of the amplifier.
- If a source unit is being used without RCA outputs, use the included high-level amplifier’s speaker terminals using the right gauge speaker wire.
- Connect your speakers to your MTX amplifier’s speaker terminals using the right gauge speaker wire. Your MTX amp can drive a 2 ohm minimum load for max power.
- 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.
CONTROL FUNCTIONS
- Gain Control – The gain control matches the input sensitivity of the amplifier to the source unit being used. The operating range varies from 200mv to 10V. Adjusting the gain:
- Turn the gain control on the amplifier all the way down (counter clockwise).
- Turn up the volume control on the source unit to approximately ¾ of maximum.
- Adjust the gain control on the amplifier until audible distortion occurs.
- Adjust the gain control down until audible distortion disappears.
- The amplifier is now calibrated to the output of the source unit.
- Phase Switch – Used to match the bass from subwoofers and front speakers. Toggle the phase switch from 0° to 180°. Keep the loudest bass response.
- Remote Control Port – Use this port to connect the optional MTX EBC. It allows you to control the output level siting at the front of the car.
- RCA Inputs – These RCA inputs are used with source units that have RCA or Line level outputs. (Source units need a minimum level of lOOmV output for proper operation of the amplifier). MTX recommends only high quality twisted pair cables (such as StreetWires) to decrease the possibility of radiated noise entering the system.
- Power On/ Protection LED – The LED illuminates red when the amp is switched on. When the amp is in short circuit or thermal protection, the LED is blinking. You need to switch off and on the amp to restart.
- Bass Boost – This can boost bass level up to 12dB. The boost frequency is centered at 45Hz.
- Subsonic – This control can filter out unwanted low frequency from 10Hz (OFF) to 55Hz. This function should only be used with vented enclosures.
- Low Pass X-Over Frequency Control – Use this to select the desired low-pass (LP) x-over frequency. The frequency is adjustable from 50Hz to 250Hz.
- 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.
- Power Terminal (+ 12V) – 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 10mm 2 power wire with the MTX TN500-
- D amplifier.
- 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”.
- 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 must 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 will be attached.
