Our take on the W12K6D4 V2 12" Subwoofers 2-Pack + KRYPTON-M3 Amplifier Bundle

A complete bass package: two Rockville W12K6D4 V2 12-inch dual 4-ohm subwoofers, a KRYPTON-M3 mono amplifier rated 1,000 watts RMS at 1 ohm, and a 4-gauge wiring kit with RCAs. The subs are CEA-compliant and rated 2,400 watts peak each, so the pair is built for heavy output in a ported or sealed enclosure. The amp's 1-ohm stability lets you wire the two dual 4-ohm subs down to a 1-ohm load and use the full rated power. It suits budget-minded bass builds where one box, one amp and one kit cover the whole install. Against pricier name-brand subs and amps, it trades refinement and long-term durability for raw output per dollar.

Pros

Cons

About the W12K6D4 V2 12" Subwoofers 2-Pack + KRYPTON-M3 Amplifier Bundle

This bundle pairs two Rockville W12K6D4 V2 12-inch car audio subwoofers with a KRYPTON-M3 mono amplifier and a 4 gauge wiring kit. Each subwoofer has dual 4-ohm voice coils and is rated at 2400 watts peak, 1200 watts program and 600 watts CEA RMS. The amplifier is a mono, 1-ohm-stable model rated at 4000 watts peak and 1000 watts Dyno-certified RMS, and it comes with a remote.

Each subwoofer has a cast aluminum basket with a black sanded finish and a fiber-reinforced, non-pressed paper cone with red stitched reinforcement. The thick foam surround and polypropylene dustcap complete the cone assembly. The 2.5-inch voice coils use a black aluminum former wound with 100% OFC copper wire. The motor has a double-stacked 100 oz magnet, an 8mm T-yoke and 8mm washer, a high BL magnetic gap, and a vented T-yoke hole for heat dissipation. High-temperature glue is used in the build.

Each subwoofer has two chrome-plated binding post terminals that accept any gauge wire. It also comes with rubber boot magnet covers and a custom mounting gasket to help seal the sub air-tight when mounted.

Questions and answers

Can the two subs be wired to 1 ohm for this amp?
Yes. Each sub has dual 4-ohm coils; wiring the pair in parallel gives a 1-ohm final load, which the KRYPTON-M3 is rated for.
What is actually in the box?
Two W12K6D4 V2 12-inch subs, one KRYPTON-M3 mono amplifier with remote, and one RWK41 4-gauge amp wiring kit with RCAs.
Is 1,000 watts RMS enough for two 12s?
It is a sensible match for this pair. The subs are rated well above that in peak terms, so the amp will not be the limiting factor in most installs.
Do I need a ported or sealed box?
Either works. A ported box gives more output around tuning; a sealed box gives tighter, more controlled bass in less space.
Will this fit my car?
Two 12s need a substantial enclosure, so measure your trunk or hatch before buying. The amp is compact enough to mount on a back panel or under a seat.
Does the amp need an upgraded alternator?
Running 1,000 watts RMS draws serious current. A healthy battery and the included 4-gauge kit cover many cars, but a larger alternator or extra battery helps.
