With your ear close to the speaker gently push on it. If it sounds scratchy then replace the speaker or consult an authorized dealer. Carefully touch the amp for temperature. If it is extremely hot then the amp is in thermal protection and needs to cool down. If thermal protection continues to be a problem, see an authorized dealer or call the technical support number below. 4. No sound from one side: Check the speaker connections, input connections, balance control on the source unit, and then

on your purchase of a new MTX Audio Thunder Amplifier! MTX has long been the industry leader in mobile enclosures and speakers, and we have reached new heights with the development of the new MTX Thunder amplifiers. You couldn’t have chosen a more reliable, powerful, or better performing amplifier. In fact, we back up every Thunder amplifier with a three-year warranty if installed by an authorized MTX Audio retailer (see the warranty statement). Your new MTX Thunder amplifier was designed, built

on your purchase of a new Class D monoblock MTX Audio amplifi er! MTX is one of the inventors of mobile audio, having designed the fi rst-ever in-vehicle enclosed subwoofer system in the early 80s. Our award-winning heritage speaks for itself, 14 Innovations Design and Engineering Awards, more than 80 AutoSound Grand Prix Product of the Year Awards, and more than 500 World Records or 1st Place Finishes in Sound Competitions. Also, MTX is the fi rst USA audio company to be awarded ISO9001 quality

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

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

It is highly recommended that installation be carried out by an authorized MTX dealer.

Connect the amplifier remote turn-on Connect the remote input terminal of the amplifi er to the remote output terminal of the source unit (only if using RCA inputs) to establish amplifi er remote on/off through the power on/off of the source unit.

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

3. Adjusting the Low, 24dB @ 40Hz-200Hz Variable Low Pass X-over Frequency Controls– • Setting for Subwoofers: Using “X-OVER” you have control over what frequency you want your amp to start crossing over your signal. By turning this control all the way counter-clockwise, you are crossing the signal over at 40Hz (the range is counter-clockwise 40Hz to clockwise 200Hz). This means that the amp will send the woofers frequencies from 20Hz to 40Hz and then start to taper down as the frequencies get o

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
