Why Choose This Product?

The NXL-F4 gives you four separately amplified channels in one flush-mount unit. Its published power ratings make it easier to compare output at 2-ohm and 4-ohm loads when planning your speaker setup. The stated bridge output provides another rating to consider when reviewing the amplifier’s supported configurations.

Use the crossover range to make installation-specific adjustments, and note that bass boost applies to the rear channels. Match speaker impedance and crossover settings to your system rather than choosing settings by output rating alone.

Installation & Compatibility Notes

Check the amplifier’s 238 x 135 x 41 mm dimensions, along with wiring and fuse requirements, before installation. Follow the manufacturer’s instructions and keep electrical connections protected from water.

A marine rating does not replace proper installation or permit intentional submersion. Confirm speaker impedance and crossover settings for your installation.
