Frequently Asked Questions
Q: Can I use this amplifier to power both speakers and a subwoofer?
A: Yes, the MHD 4-channel is ideal for complete system installations. Run channels 1-2 to front speakers and bridge channels 3-4 for a subwoofer (300W RMS), or run all four channels to speakers and add a separate monoblock for subwoofer duties. The flexible crossover controls allow precise tuning for each application.
Q: What's the difference between 2-channel and 4-channel input mode?
A: 2-channel input mode uses channels 1-2 inputs to feed all four output channels (1 mirrors 3, 2 mirrors 4), ideal for 2-channel source units. 4-channel mode uses independent inputs for each channel pair, allowing front/rear fading from 4-channel source units or processors.
Q: How much current does this amplifier draw from my boat's electrical system?
A: At full rated output, the MHD 4-channel draws approximately 60-70 amps from a 12V system. The efficient Class D design reduces current draw compared to older Class AB amplifiers. Ensure your boat's alternator and battery system can support this load, especially when running multiple amplifiers.
Q: Can I mount this amplifier in an exposed location?
A: While the MHD features marine-grade construction with conformal coating, it's not fully waterproof. Mount in a protected location away from direct water spray, such as under seats, in storage compartments, or inside an amplifier enclosure. Avoid bilge areas or locations that may be submerged.
Q: What speaker impedance should I use for best performance?
A: The MHD 4-channel delivers 150W RMS per channel at both 2-ohm and 4-ohm loads. Use 4-ohm speakers for most installations as they're easier on the amplifier and electrical system. When bridging, present a 4-ohm load to the bridged channel pair (using two 8-ohm speakers in parallel or one 4-ohm speaker).
