Installation - MTX Terminator TN8MS Owner's Manual

INSTALLATION

MTX recommends your new TN8MS powered enclosure to be installed by an Authorized MTX
retailer. Any deviation from specified installation instructions can cause serious damage to the
amplifier, subwoofer and/or vehicle's electrical system. Damage caused from improper installation is
NOT covered under warranty. Please verify all connections prior to turning on your system!
1. Disconnect the vehicle's negative battery cable.
2. Determine the mounting place for your MTX TN8MS. Keep in mind there should be sufficient air
flow for proper cooling.
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 (1). 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 8" 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.
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 amplifier (3).
6. Connect a remote turn-on wire from the source unit to the amplifier remote terminal (2). If the
source unit does not have a dedicated Remote Turn-on lead, you may connect to the source unit's
Power Antenna lead.
7. Connecting signal cables to the amplifier: There are two ways to supply the signal to your MTX
TN8MS.
• To get maximum performance, we suggest connecting a high quality RCA to the corresponding
outputs at the source unit and inputs of the amplifier (6).
• If a source unit is being used without RCA outputs, use the included high-level amplifier's
speaker terminals (8) using the right gauge speaker wire.
8. 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.
