Frequently Asked Questions - MX150.2-24V Memphis Audio
What is the MX150.2-24V amplifier used for?
This is a 2-channel amplifier designed for 24V electrical systems commonly found in trucks, RVs, and marine applications. It can power two speakers or one bridged subwoofer.
Can I bridge the amplifier for more power?
Yes, the MX150.2-24V is bridgeable. When bridged into a single channel, it delivers up to 300W RMS at 8 ohms. Ensure your subwoofer is compatible.
What size fuse do I need?
Use an external 25A fuse on the power wire close to the battery. Never exceed this rating to protect the amplifier.
How do I adjust the crossover?
The amplifier has built-in low-pass (LPF) and high-pass (HPF) filters. Use a small flathead screwdriver to adjust the crossover frequency between 50 Hz and 250 Hz.
What is the recommended speaker impedance?
For stereo operation, use 4-ohm speakers per channel. In bridged mode, the minimum impedance is 8 ohms. Lower impedances may cause overheating.
Can I install this in a car with a 12V system?
No, this amplifier is designed specifically for 24V systems. Using it on 12V will result in significantly reduced power output and may cause issues. Use a 12V model instead.
Does it work with marine speakers?
Yes, the amplifier is suitable for marine environments if mounted in a dry location. It has corrosion-resistant connectors but is not fully waterproof.
How do I clean the amplifier?
Unplug the power, then wipe the exterior with a soft, dry cloth. Do not use any liquids or cleaners that could enter the ventilation slots.
What should I do if the amplifier goes into protection mode?
Protection mode indicates an issue such as overheating, short circuit, or over-current. Check speaker wiring, ensure proper ventilation, and verify the impedance load. If the problem persists, consult a professional.
