NSW410 10″ car subwoofer

The ALPHASONIK NSW410 is a 10-inch car subwoofer built for drivers who want deeper bass without a massive enclosure. Its dual voice-coil design and 4 Ohm impedance suit single-sub installations in sedans, hatchbacks or compact SUVs where space is tight. Buyers who need more storage or a second subwoofer for SPL competition will find the single-unit format limiting.

Sustained 400 W RMS output

Rated at 400 watts RMS and 1200 watts peak, the NSW410 maintains consistent output during extended listening sessions rather than only short bursts. The 55 oz magnet and laminated non-pressed pulp cone with fiberglass keep distortion low when driven continuously. Sensitivity of 85 dB at 1 W/1 m means moderate amplifier power delivers usable volume.

Straightforward enclosure mounting

Mounting depth is 128 mm with a 233 mm cut-out and 270 mm overall diameter, so the woofer drops into standard sealed or ported boxes. Eight-gauge nickel-plated terminals accept heavy speaker wire without adapters. The stamped-steel Alpha basket and EPDM surround tolerate temperature swings, but installers must verify their enclosure volume matches the 35–500 Hz response range for best results.

Questions about this item

How much heat and power does the 400 W RMS subwoofer generate during long listening sessions?

The NSW410 is rated at 400 W RMS with 85 dB @ 1w/1m sensitivity and a 55 oz magnet; it draws the current needed for that output and its EPDM surround is designed for extreme temperatures, so heat stays controlled under continuous use.

What amplifier and wiring must I already own to run this 4 Ohm dual voice-coil subwoofer?

You need a mono or bridged amp stable at 4 Ω (or 2 Ω / 8 Ω depending on how the dual coils are wired) that can deliver around 400 W RMS, plus 8-gauge or thicker power and ground cables and the 8-gauge nickel-plated terminals on the sub accept standard ring terminals.

Will this 10-inch NSW410 fit the same cut-out and depth as my old 10-inch subwoofer?

The mounting depth is 128 mm (5.04 in) and the cut-out diameter is 233 mm (9.17 in) with an overall diameter of 270 mm (10.63 in); compare those figures to your existing enclosure to confirm fit.
