Congrats and enjoy the ultimate audio experience with MTX ! Specifications :

• 2-Channel Class-AB Amplier

• CEA2006 certied Power Output : - 90 watts RMS x 2-channel at 2 ohm and THD+N ≤1% - 60 watts RMS x 2-channel at 4 ohm and THD+N ≤1% - 180 watts RMS x 1-channel at 4 ohm and THD+N ≤1%

• Crossover : - High pass 12dB/oct variable from 40Hz to 400Hz - Low pass 12dB/oct variable from 40Hz to 400Hz

• High level inputs Control PanelControl Panel : Gain Control (GAIN) : The gain control matches the input sensitivity of the amplier to the source unit being used. The operating range varies from 100mv to 6V. Adjusting the gain

1. Turn the gain control on the amplier all the way down (counter clockwise).

2. Turn up the volume control on the source unit to approximately 3⁄4 of maximum.

3. Adjust the gain control on the amplier until audible distortion occurs.

4. Adjust the gain control down until audible distortion disappears.

5. The amplier is now calibrated to the output of the source unit.

Low-Pass High-Pass X-Over Switch (X-OVER) : In “LPF” position, the active low pass (LP) x-over is turned on In “HPF” position, the active high pass (HP) x-over is turned on In “FULL” position, the x-over is turned o High Pass X-Over Frequency Control (HPF) : Used to select the desired high-pass (HP) x-over frequency. The frequency is adjustable from 40Hz to 400Hz.. Low Pass X-Over Frequency Control (LPF) : Used to select the desired low-pass (LP) x-over frequency. The frequency is adjustable from 40Hz to 400Hz.. RCA Inputs (LOW INPUT) : These RCA inputs are used with source units that have RCA or Line level outputs. (Source units need a minimum level of 100mV output for proper operation of the amplier). MTX recommends only high quality twisted pair cables (such as StreetWires) to decrease the possibility of radi- ated noise entering the system. RCA outputs - These RCA output jacks are for connecting multiple ampliers to 1 stereo RCA lead coming from the source unit (daisy chaining). PowerOn/Protection LED - The LED illuminates red when the amp is switched on. When the amps is in shortcir- cuit or thermal protection, the LED is blinking. Speaker level inputs (HLI) : This input will allow the amplier to operate from source units with speaker-level outputs. Output speaker leads from the source unit should be tied directly to the wire harness provided with the amplifier. Note : When speaker level inputs are used, a remote turn on wire must used to switch the amplier on and o. (+12V) Power Terminal : This is the main power input for the amplier 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 con- nection for maximum performance. MTX recommends using 10mm

power wire with the MTX RT60.2 amplier. Remote Terminal (REM) : The amplier can be turned on by applying 12 volts to this terminal. Typically this volt- age is supplied by a wire from the source unit marked “remote” or “power antenna”. Ground Terminal (GND) : A proper ground is required for your amplier 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 will be attached. Speaker Terminals (SPEAKER) : 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 amplier, use the right positive terminal and the left negative terminal only.

Warning : do not bridge the amplier with an impedance lower than 4 ohm.

Fuse (FUSE) : When fuse blow, replace them with the same value. Never use a higher rated fuse !www.mtxaudio.com - www.mtxaudio.eu Owner’s Manual - RT60.2 Installation & Mounting MTX recommends your new Thunder amplier be installed by an Authorized MTX retailer. Any deviation from specied installation instructions can cause serious damage to the amplier, 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 amplier. Keep in mind there should be sucient air ow for

proper cooling. Mark the mounting holes from the amplier 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 rewall using a grommet or rewall

bushing to avoid cable damage from sharp edges of the rewall. Run the cable through the interior of the vehicle and connect it to the amplier’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 eectively 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 o 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 amplier.

6. Connect a Remote Turn-on wire from the source unit to the MTX amplier’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.

7. Connecting signal cables to the amplier : There are two ways to supply the signal to your MTX 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 amplier’s speaker terminals using the right gauge speaker wire.

8. Connect your speakers to your MTX amplier’s speaker terminals using the right gauge speaker wire. Bridged

channels can drive a 4 ohm minimum load for max power.

9. Double check all previous installation steps, in particular, wiring and component connections. Once veried,

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 amplier should be turned all the way down (counter clockwise) before proceeding with adjustments.Troubleshooting Problem Cause Solution No LED indication No +12V at remote connection Supply +12V to terminal No +12V at Power connection Supply +12V to terminal Insu cient ground connection Verify ground connection Blown power fuse Replace fuse Power LED on, no output Volume on source unit o Increase volume on source unit Speaker connections not made Make speaker connections Gain control on amplier o Turn up gain Signal processing units o 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 L + R 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 Amplier defective Return for serviceSPEAKER BRIDGE
