Do not connect to Factory bolts of ANY kind. When attaching the ground to the chassis, sand all the paint away from the contact point, a grounding block like the StreetWires GT4 should be used whenever possible, this piece of equipment has 5 times the surface area a normal screw has. The gauge of the power and ground wire is often an overlooked aspect of amplifier installation. The more power the amplifier receives, the more power it will produce. Power cables have a natural resistance, and will lose voltage by the time the power makes its way to the amplifier. The larger gauge (diameter) wire will hold more voltage over longer runs. Also by having a larger diameter ground wire, the amplifier can run more efficiently. MTX recommends using a minimum of 8 gauge power and ground cables to get the best performance. • REM: This connection turns the amplifier on and off and needs to be connected to a remote Turn-on wire from your source unit if you are using a low level input connection. Note: When numerous amplifiers are used in the same system, look into using a relay with a separate power wire connected to an alternative power source to take the strain off the source unit. Normal source units can only keep a constant 12 volts to 2 maybe 3 amps. This wire should also be run on the away from the RCA cables. Double check all the previous connection installation steps, in particular, the speaker and power wiring. Securely mount the amplifier. If everything is in order, reconnect the vehicles negative battery connection and begin following the feature setup and adjustment steps. Feature Setup and Adjustments 1. Selecting The Input Sensitivity Range – Before you turn on your system, you must select the proper input sensitivity range on your amp using the button labeled INPUT SENS located in the GAIN CONTROL section of the control panel. • Setting for aftermarket Source Units: Refer to your aftermarket owner’s manual for line level output specification. If the specification is not available, please follow the instructions listed below. X1 POSITION: 100mV – 1V (Typically for RCA Input) • Setting for factory (OEM) Source Units: To check the amount of voltage that is present from the source unit, take a multi meter, or a volt/ohm meter, on the A/C setting, (range from 100mv up to 10 volts) attach the positive and negative leads directly to any exposed speaker. It will not matter if the polarity is correct, it will read the same amount of voltage. X10 POSITION: 1V – 10V (Typically for Speaker Level Input) Note: It is important not to have the amp set up to receive a low voltage signal and give it a high voltage signal. Doing this can cause damage to the amp. 2. Adjusting The Mono Gain Control – Before you start setting your amp gains, be sure to defeat all “EQ’s” (“off” position). You want to set the gain levels properly BEFORE applying any equalization. Start with the source unit’s volume around . of the way up, and the gain on the amp all the way down (counterclockwise). Slowly increase the gain clockwise until the speaker starts to distort. Immediately decrease gain until the distortion goes away. This will be a good reference point on the volume control to where the signal starts to distort. Remember every CD will be different, use common sense and constantly listen for obvious distortion and adjust volume accordingly. The gain on the amp has nothing to do with how much power the amp can produce, just how fast the amp puts out max power. Just like in an automobile, full throttle is very rarely needed. 3. Adjusting the Low @ 80Hz, 24dB or 120Hz, 24dB Selectable Low Pass X-over Frequency Switch– • Setting For Subwoofers: First set the electronic crossover by selecting the “80Hz” position or the “120Hz” of the X-OVER switch. By selecting the “80Hz” setting, the amp crosses the signal over at 80Hz with a 24dB/ Oct roll off. Meaning the signal tapers off fairly quickly at frequencies over 80Hz. By selecting the “120Hz” setting, the amp crosses the signal over at 120Hz with a 24dB/Oct roll off. Meaning the signal tapers off fairly quickly at frequencies over 120Hz. 4. Adjusting The Fixed ThunderEQ – Depress the BASS BOOST button located in the PROCESSOR section of the control panel to supply 12dB of a 40Hz bass boost to enhance the low frequency response of your system. Depress the BASS BOOST button to achieve a smooth flat response on in the low frequency range. 5. Remote Subwoofer Level Control (Remote Sub) – Lets say the amplifiers gain is set at half way, when the remote subwoofer level control is plugged in, you now have external control of the gain from zero – half way. The installation of this level control is NOT necessary to get full power from amplifier. Note: One Remote Subwoofer Level Control can control two or more amplifiers using a mini plug Y adaptor. 6. Prizm EFX – Now that you have completed adjusting all your amplifier settings, you can set the lighting effects to you personal taste. • Selecting Colors: ...
