Bring better bass to your boat

This Kenwood P-WD250MRW marine bass package includes a water-resistant 10" subwoofer and a compact power amplifier. It's a combo that's sure to shape up the bass in your boat.

Kenwood's KFC-W250MRW 10" marine subwoofer combines a strong, waterproof polypropylene cone with a rubber surround that'll hold up to humidity and UV exposure. A tough white plastic shell protects the basket and magnet against corrosion, and the sub's integrated white plastic grille matches the interior of many boats. The sub's dual-voice coil design ensures you'll get maximum power out of the amp.

Kenwood designed this marine subwoofer for free-air use, so it'll produce great bass when mounted into a panel or bulkhead — no box required. Stainless steel mounting hardware is included.

The KAC-210MR marine amplifier packs plenty of power into a small package, thanks to Kenwood's engineering expertise. Special coated circuit boards ensure the amp will keep the power flowing even after prolonged exposure to dampness. The amp's output is tailored to work perfectly with the subwoofer.

Subwoofer Features

Overview: This package includes a KFC-W250MRW dual voice coil marine subwoofer and a KAC-210MR mono amplifier designed for use with the subwoofer.

UV and Water Resistant: The subwoofer features a UV-resistant white grille, waterproof pearl mica polypropylene cone, rubber surround, and stainless steel mounting hardware. The tinsel leads are coated and the speaker terminals are gold-plated to guard against corrosion. The amplifier has a special coated circuit board to protect it against the marine environment.

Free-Air Subwoofer Design: The woofer is designed for mounting in an infinite baffle (free-air) application, so no enclosure is necessary.

Vented Voice Coil: The subwoofer's vented voice coil allows air to circulate in the voice coil gap, helping dissipate heat, resulting in greater power handling and increased reliability.

Subwoofer Mounting: The measurements in the Crutchfield database are taken without the grille. With the grille installed, the mounting height increases to 0.983" and the frame diameter increases to 10.766".

Amp Features

Matching Amplifier: The KAC-210MR mono amplifier is a special amplifier designed to handle the low impedance load of the subwoofer. The subwoofer has dual 1.5-ohm voice coils, and when connected in parallel to the amplifier, present a 0.75-ohm load to the amp.

Fixed Input Sensitivity: The amp has a fixed input sensitivity of 60mV (0.06 volts). There is no gain control on the amplifier.

Note: In order to control the volume of the subwoofer relative to the rest of the system, you will need a head unit with a variable volume control on the subwoofer preamp output, or an external remote level control (such as 136CLRLC).

Low-pass Filter: The amplifier has a low-pass filter with a fixed cutoff frequency of 80Hz.

Inputs and Outputs

Amp Unit:

  • Power: 10-pin jack for use with the supplied Connector cord
  • Subwoofer Output: 4-pin jack for use with the supplied Speaker cord
  • Line In: Stereo RCA audio jacks

Specifications

Amp Unit:

  • Maximum Output: 200 watts
  • Signal-to-Noise Ratio: 85 dB
  • Low-pass Filter Frequency: 80 Hz
  • Sensitivity/Input Impedance: 60mV / 10 kΩ
  • Output Impedance: 1.5 Ω + 1.5 Ω = 0.75 Ω

Q
I have a blue tooth bazooka 6 speaker sound bar on my ATV, and it has a 3.5mm output port for a subwoofer, or so bazooka says. If I were to get a 3.5mm - DUAL RCA output cord, would this amp and sub work with that as an input from the sound bar?

Based on the information you've provided, yes, that should work. You can use the 80Hz low pass crossover of the Kenwood amp to eliminate the mid-range & high frequencies from the subwoofer. I hope that helps. My Bio: https://www.crutchfield.com/bio/Ryan

Q
I installed this speaker and amp combo in my boat. When I energized the power the speaker was cutting in and out and the blue power light on the amp was flickering. The louder the music was turned up the less the speaker would work at all? I installed the system the same as the diagram showed and I am not sure why the amp is powering on and off. Any help will be greatly appreciated.

Q
I am having this Kenwood sub. and amp. installed in my boat, and would like to know how much hollow space is needed behind it to make it sound best?

It is a free-air sub so you don't need hardly any space just make sure the magnet is not touching the boat in the back and you will be fine.

I will say not much. I have mine installed in the bottom of my port side bench. Its also a storage compartment crammed with stuff so not much breathing room back there . It sounds really good. Im pleased. Its installed on a searay 240 sundeck.

I Have about 12 inches and it sounds good.

Q
What would be the best way to wire this set up ? Should I parallel or in series and should I bridge the amp ?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss the best option for wiring. They will be able to pull up your gear and see how this will best integrate.
