Frequently Asked Questions - Thunder TH900.6 MTX Audio
What is the RMS power output of the MTX Audio Thunder TH900.6?
The MTX Thunder TH900.6 delivers 100 watts RMS per channel at 4 ohms and 150 watts RMS per channel at 2 ohms, for a total of up to 900 watts peak. This makes it suitable for powering speakers and subwoofers in a variety of configurations.
What are the dimensions and weight of the amplifier?
The amplifier measures approximately 13.4 x 6.3 x 2.1 inches (340 x 160 x 54 mm) and weighs 5.5 lbs (2.5 kg). Ensure sufficient clearance around the heatsink for proper heat dissipation.
What type of power connection does it require?
The TH900.6 operates on a 12V DC electrical system with negative ground. You should use a fused power wire (typically 2 or 4 AWG) connected directly to the battery positive terminal, and a ground wire of the same gauge connected to a clean chassis ground. The amplifier is protected by three 25A fuses.
How do I properly set the gain controls?
Set your head unit volume to about 75% of maximum, then turn the gain control on the amplifier until you hear audible distortion, then reduce it slightly. Use a digital multimeter or oscilloscope for precise settings. The goal is to match the amplifier input sensitivity to the head unit output without clipping.
Does the amplifier have a built-in crossover?
Yes, each pair of channels is equipped with a variable low-pass, high-pass, and bandpass crossover. This allows you to route bass to subwoofers and midrange to full-range speakers, creating a smooth frequency separation without an external processor.
Can I bridge channels to power a subwoofer?
Yes, the TH900.6 can be bridged. For example, channels 5 and 6 can be bridged to produce a higher mono output, typically 300W RMS at 4 ohms. Consult the manual for correct wiring and minimum impedance loads to avoid damage.
What are the main protection features?
The amplifier includes thermal protection that shuts down if it overheats, short-circuit protection on outputs, and DC offset protection on the power supply. These safeguards help protect both the amplifier and your speakers from damage.
How do I connect it to a factory head unit?
You can use the speaker-level inputs instead of RCA connections. Simply connect the factory speaker outputs to the amplifier's high-input harness. This is ideal when your factory stereo lacks RCA preamp outputs. Make sure to set the input sensitivity accordingly.
What maintenance is required?
Periodically inspect the wiring connections for tightness and corrosion. Clean the exterior with a soft dry cloth. Ensure the heatsink is free of dust and debris. Regular maintenance helps maintain performance and longevity.
Can I repair the amplifier myself?
For safety and reliability, only an authorized service technician should attempt internal repairs. The user-replaceable parts are the fuses. If the amplifier is under warranty, contact MTX Audio for service. Do not open the case to avoid electrical shock.
