Description

Product Overview

Add dedicated two-channel power to your marine audio system with the DS18 NXL-M2 2-channel marine amplifier. Its Class D design delivers 400W RMS per channel at 2 ohms or 250W RMS per channel at 4 ohms.

Use its separate amplified channels to power multiple speakers from one unit, with selectable HPF, LPF, or FULL crossover settings for system setup.

Key Features & Benefits

  • Two-channel Class D output: Choose stereo amplification for speakers connected to the amplifier.
  • Power at two loads: Match the published per-channel RMS rating to speakers with a 2-ohm or 4-ohm impedance.
  • Selectable crossover: Choose HPF, LPF, or FULL and adjust the filter within the listed range.
  • Marine-rated construction: IP55 water-splashing resistance, UV protection, and coated PCB help suit marine installations.
  • Input options: Use low-level RCA or two-channel speaker-level input, depending on your source connection.
  • Protection indicators: Clipping, protect, and power LEDs help you monitor amplifier status.

Why Choose This Product?

The NXL-M2 combines two amplified channels with selectable crossover modes and both low- and high-level inputs. Its published ratings make it easier to compare output against your speaker impedance before choosing an amplifier.

Its IP55 water-splashing rating and UV-protected, coated PCB address marine-use considerations. The rating does not mean the amplifier can be submerged.

Installation & Compatibility Notes

Check the 9.6" x 4.5" x 1.7" overall dimensions and mounting space before installation. Match speaker impedance to the operating mode: the minimum is 2 ohms in stereo or 4 ohms bridged.

Plan for the 4 Ga power input terminal and 80A (2x40A) fuse requirement. Follow the manufacturer instructions and keep connections protected from water; the amplifier is not intended for intentional submersion.

Frequently Asked Questions

What RMS output does the DS18 NXL-M2 provide?

It is rated at 2 x 250W RMS at 4 ohms and 2 x 400W RMS at 2 ohms. The listed bridged output is 1 x 880W at 4 ohms.

What is the minimum speaker impedance?

The minimum is 2 ohms for stereo operation and 4 ohms when bridged. Match your speaker load to the mode you plan to use.

Can I connect a source with speaker-level output?

Yes. The amplifier has two-channel speaker-level input, listed as ≥5V. It also has low-level input with a 0.2V-6V range.

Can the amplifier be submerged?

No. Its IP55 rating is specified for water splashing, and the installation guidance says not to intentionally submerge it.

What space and fuse should I plan for?

Allow for the listed overall dimensions of 9.6" x 4.5" x 1.7" and the 80A (2x40A) fuse requirement.
