Frequently Asked Questions - KXMA400.4 KICKER
What is the recommended speaker impedance for this amplifier?
The KXMA400.4 is stable down to 2 ohms per channel in stereo mode and 4 ohms bridged. For best performance and reliability, use speakers with an impedance of 4 ohms or higher per channel.
Can I bridge two channels for more power?
Yes, you can bridge channels 1&2 and 3&4 to deliver up to 300W RMS into a 4-ohm load. Ensure the speaker impedance is at least 4 ohms when bridged.
What size power and ground wire should I use?
For the KXMA400.4, use at least 4 AWG power and ground cables for optimal current flow. The amplifier has a 40A fuse requirement.
Does this amplifier come with a remote bass control?
Yes, the KXMA400.4 includes a remote gain control module that allows you to adjust the volume from the driver's seat.
Is the KXMA400.4 suitable for marine applications?
Absolutely. This amplifier features a conformal coated PCB and an IPX6 water-resistant rating, making it ideal for boats and other marine environments.
How do I set the gain correctly?
Set the gain using the input sensitivity control. Start with the gain fully counterclockwise, play music at 3/4 volume, then adjust until you hear distortion, then back off slightly.
What is the frequency response of this amp?
The amplifier has a frequency response of 20Hz to 20kHz (±1dB), ensuring full-range audio reproduction.
Can I run this amplifier at 1 ohm?
No, the KXMA400.4 is not stable at 1 ohm. Operating below 2 ohms per channel or 4 ohms bridged may cause overheating or damage.
What type of fuse does the amplifier use?
It uses a single 40A AGC blade fuse located on the end panel. Always replace with the same rating.
How do I clean and maintain the amplifier?
Use a soft dry cloth to wipe the exterior. Avoid liquids and solvents. Periodically check all connections and ensure the amplifier is mounted in a well-ventilated area.
