Marine Audio Pair for Open Vehicles

The MB Quart NK2-116W is a 6.5 inch white coaxial speaker pair built for boats, RVs and off-road machines. Each unit carries IPX67 certification, UVA protection and conformal coating so water, salt spray and sun exposure do not degrade the cones or the titanium tweeters. Rust-resistant connectors and supplied white grilles complete the weather-ready package for open-cockpit installations.

Sustained Output at Certified Levels

CEA-426B testing rates continuous power handling at 60 watts RMS with 120 watts peak, so the speakers maintain clean output during long cruising sessions without thermal compression. Sensitivity of 87.7 dB at one watt and one metre means moderate amplifier power reaches comfortable listening levels. The 4 ohm impedance presents an easy load for most marine-rated amplifiers across the 35 Hz to 21 kHz bandwidth.

Installation Checks Before Ordering

Verify the mounting hole matches the 5.59 inch cut-out and that 3.7 inch of depth is available behind the panel. Allow 1.13 inch of protrusion for the grille and gasket assembly. Confirm your amplifier delivers clean power into a 4 ohm load and that wiring reaches the supplied rust-resistant terminals. Buyers needing larger cone area or higher continuous SPL for big open decks should look elsewhere.

Questions about this item

How much continuous heat or power draw should I expect from the 60 W RMS speakers during all-day use?

The pair is rated for 60 W RMS per CEA-426B, with 87.7 dB sensitivity and 4 ohm impedance, so sustained output stays moderate and thermal load is low for a marine coaxial design.

What amplifier or head-unit specs must I already have to drive these 4 ohm, 60 W RMS speakers?

You need an amplifier or head unit that delivers up to 60 W RMS per channel into 4 ohms and provides a standard speaker-level output; the included grilles and rust-resistant terminals simplify the connection.

Will the 5.59 inch cutout and 3.7 inch mounting depth fit the existing holes in my older boat console?

The speakers require a 5.59 inch cutout and 3.7 inch depth behind the panel; measure your current openings against those dimensions before installing.
