Frequently Asked Questions - Thunder TH400.4 MTX Audio
What is the recommended speaker impedance for the Thunder TH400.4?
The amplifier is stable down to 2 ohms per channel in stereo mode and 4 ohms bridged.
How do I set the gain on the TH400.4?
Use a multimeter or oscilloscope to set the gain properly. Start with the gain at minimum, play a test tone at 0 dB, and adjust until the output voltage matches the desired power.
Can I bridge two channels for a subwoofer?
Yes, bridge channels 1/2 and 3/4 for two subwoofers. Ensure the subwoofer is 4 ohms or higher when bridged.
What type of input does the TH400.4 accept?
It accepts RCA inputs for aftermarket head units and has speaker-level inputs for factory radios.
How do I adjust the crossover filters?
Use the built-in low-pass and high-pass filters. Set the dip switches to choose between HPF, LPF, or full-range. Adjust the frequency knob from 40 Hz to 400 Hz.
What size power wire should I use?
Use 4 AWG power and ground wire for optimal performance. Ensure the ground is connected to a clean metal surface.
Why is my TH400.4 going into protect mode?
Protect mode can be triggered by a short circuit, overheating, or low impedance. Check all connections and ensure the amplifier has proper ventilation.
Can I use the TH400.4 with a stock stereo?
Yes, use the speaker-level inputs and connect directly to the factory speaker wires. Avoid using high-level inputs if the stereo has a built-in amplifier.
What is the maximum power output of the TH400.4?
The amplifier can deliver up to 600W max (bridged) or 300W x 2 RMS at 4 ohms bridged.
How do I clean and maintain the TH400.4?
Keep the amplifier dry and dust-free. Use a soft brush or compressed air to clean the heatsink. Avoid using liquid cleaners.
