Why Choose Rockford Fosgate TM400X4AD Marine Amplifier?
Featuring Constant Power
The Power TM400X4ad 400 Watt 4-channel ultra-compact amplifier is built on Rockford Fosgate’s proprietary Class-AD technology, featuring Constant Power to produce the same output at both 4-Ohm and 2-Ohm impedances. Flexible vehicle integration enabled through low-level and high-level inputs with auto turn-on.
Easy Access to Built-in Crossover
< p> Top-mounted controls allow easy access to built-in crossover and C.L.E.A.N. input/output clip detection circuits. The 3-stage thermal lock extrusion with dual fan forced induction keeps everything cool while real-time thermal/protection schemes safeguard the amplifier.
Made to Handle Moisture and Heat
It's built to stand up to outdoor life, too, with conformal-coated circuitry that withstands moisture and dirt and stainless steel hardware that won't succumb to corrosion. With a 3-stage thermal lock extrusion, dual- fan forced induction system, and real-time thermal monitoring, the TM400X4AD can rock hard without overheating – even when it's tucked into a tight space.
Frequently Asked Questions (FAQ)
- • Why does the amplifier have no power?
Check the fuse, battery connection, ground, and power cable. Loose connections or a poor ground can prevent the amplifier from turning on.
- • Why does it keep going into protection?
Check for shorted speaker wires, incorrect impedance, overheating, or weak power connections. Make sure the load is within the amplifier's limits.
- • Why does the sound cut out at high volume?
Low voltage, overheating, excessive gain, or an unsuitable speaker load can cause shutdowns. Check the power supply and amplifier settings.
- • Why do I hear a whining noise through the speakers?
Whining is often caused by grounding or signal interference. Check the ground connection and keep signal cables separated from power wiring.
- • Why is one channel not producing sound?
Check the RCA inputs, speaker wiring, gain controls, and source output. Swap channels to determine whether the issue follows the input or speaker.
- • Why does the amplifier get very hot?
Some heat is normal, but excessive temperature may indicate poor ventilation, high output, or an incorrect load. Allow adequate airflow around the unit.
- • Can it be used safely on a boat?
It is designed for marine applications, but proper installation is still important. Protect connections, use suitable wiring, and mount the amplifier securely.
- • Why does the audio sound distorted?
Distortion can come from excessive gain, clipping, or an unsuitable speaker load. Lower the gain and check the source and amplifier settings.
- • Why does the amplifier shut off after getting wet?
Check for moisture around connections and terminals. Dry the area completely and inspect for corrosion or damaged wiring before restoring power.
- • What should I check if it suddenly stops working?
Inspect the fuse, power, ground, speaker wiring, and signal connections. Look for loose or damaged cables and check the amplifier's protection status.
