Kenwood P-wd250mrw Includes Kfc-w250mrw 10 Marine Subwoofer Kac-210mr Amplifier on 2040-parts.com

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. You can connect the amplifier to any radio, and 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 our 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
