6. Variable Hi, 12dB / Low, 24dB Mono @40Hz–350Hz X-over – This control allows the user to choose the exact low pass or high pass frequency range the amplifier will play for the best possible performance. A high pass or full range output may be selected for the front output. A high pass, low pass, or full range output may be selected for the rear output. The upper end of the low pass crossover range can be selected from 40Hz–350Hz at 24dB per octave with a mono output. The lower end of the high

Be sure to lay the signal wire away from all power cables and vehicle computers. Use high quality twisted pair interconnect cables to decrease the possibility of radiated noise entering the system. • Using RCA Connections: If the source unit has RCA outputs, simply attach a signal cable from the source unit to the amp’s RCA input. This will provide signal to the amp. • Using Speaker Level Connections: If the source unit does not have RCA outputs, a high level signal can be used instead by takin

Normal source units can only keep a constant 12 volts to 2 or possibly 3 amps. This wire should also be run on the away from RCA cables. • CAP+: This 8 gauge terminal is internally wired in parallel with the +12V on the StreetWires Power connector. It is the ideal connection point for the positive side of a capacitor to increase the amplifier’s performance. • CAP-: This 8 gauge terminal is internally wired in parallel with the GND on the StreetWires Power connector. It is the ideal connection po

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 owne

With this setting, the Remote Gain can directly control the amplifi er playback level. 3. When the full range is selected (FR), the amplifi er is used as a full range amplifi er. CROSSOVER FREQUENCY SELECTION (FREQ) Both the high-pass and the low-pass section offer continuously adjustable crossover frequencies between 40Hz and 350Hz. Adjust the setting according to your speaker component specifi cation or to your particular preference. BASS BOOST CONTROl (BASS BOOST) Select a boost level between

Any deviation from the recommended connection procedures may cause serious damage to the amplifier, speakers, and/or vehicle electrical system. Please double check the connections before turning the system on. Installation Mounting Place your Thunder amplifier at the predetermined mounting location. Use a felt pen to mark the exact position of the mounting holes on the mounting surface. Set the amplifier aside. With a sharp, precise blade cut small circles in the carpet and padding around the fo

This means that the amp will send the components or separates frequencies from 40Hz to 20kHz and then start to taper down as the frequencies get under 40Hz (octave roll off). The industry standard for high pass setting or X-over point is around 120Hz. When the amp is in HP setting and the X-over point is set to 120Hz, the amp is sending the speakers frequencies from 120Hz to 20kHz. This crossover network allows the drivers to recreate the frequencies within a precisely designed range so that the

Adding MTX amplifiers and matching MTX speakers and subwoofers with StreetWires connections will put you in a better position to hear, feel, and experience all of the music the artist intended.

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. X
