Marine 4-inch 2-way speakers

The Pyle PLMRWK49BK is a pair of waterproof 4-inch two-way box speakers built for marine watercraft ATVs UTVs and Jeeps. Each unit handles 150 watts peak power with a 4 ohm impedance and 90 dB sensitivity. The frequency response spans 70 hertz to 20 kilohertz for full-range stereo output.

Rotatable brackets and IPX5 rating

The 360 degree rotatable brackets allow flexible mounting on roll bars or roll cages in multiple orientations. An IPX5 waterproof rating protects the polypropylene cone and butyl rubber surround from spray and wash-down. A one-inch neodymium dome tweeter adds crisp highs without extra wiring.

Check amplifier power and mounting space

Verify your amplifier can deliver clean power into a 4 ohm load at the speaker’s rated sensitivity. Confirm the slim ABS cabinet dimensions fit the intended roll-bar or dash location before ordering. Ensure the wiring run can reach the speaker terminals without strain.

Questions about this item

Will the butyl rubber surround on the 4" polypropylene woofer need replacement after extended marine use?

The butyl rubber surround is chosen for durability in wet conditions and resists rot, so it typically lasts the life of the speaker without needing replacement.

At 150W peak power, does the 1-inch aluminum voice coil overheat first during long playback?

The 1-inch aluminum voice coil handles the 150W peak rating, and the 90 dB sensitivity means it reaches loud volumes with less amplifier strain, reducing heat buildup during sustained use.

How much heat do the 10 oz magnets and ABS housing produce when the speakers run all day on a UTV?

The 10 oz magnet structure and molded ABS cabinet dissipate heat passively; with 4-ohm impedance and 90 dB sensitivity, the speakers run cool enough for continuous daily operation without thermal issues.
