PioneerSKU: TS-A301D4



Bring your tunes alive

I don't think it's an exaggeration to say that a good sub will make your car's sound system come alive, and Pioneer's Champion Series subs provide the deep low-frequency punch to make it happen. The TS-A301D4 12" subwoofer handles up to 500 watts RMS while pumping out loud, clean bass. This sub features Pioneer's  Honeycomb IMPP™ cone for exceptional strength and a dual-layer, fiber and reinforced elastic surround that supports the woofer during cone excursion for accurate, hard-hitting bass notes when you crank the tunes. 

Enhance your ride

This potent Pioneer's dual 4-ohm voice coils give you more wiring options when setting up your system. Throw one or two of these subs in your ride, power them up with a nice amp, and you'll understand — whatever you listen to, great bass will make it sound much, much better.

Product Research


Woofer Cone: Pioneer uses an IMPP (Injection Molded Polypropylene) woofer cone. This process of cone molding assures a uniform cone thickness for superior linearity and clarity.

Dual 4Ω Voice Coils: This woofer features two 4Ω voice coils that offer wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 2Ω load. When the voice coils are wired in series, the woofer presents an 8Ω load.

Terminals: The spring post terminals will accept pin connectors, single banana plugs, or bare wire up to 10 gauge.

Sealed Box Volume: Pioneer recommends a sealed enclosure with an internal volume between 0.85 ft³ and 1.75 ft³, with an ideal volume of 1.25 ft³. Sealed enclosures provide the most control over the woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.

Ported Box Volume: The recommended ported box volume ranges from 1.25 ft³ to 2.0 ft³, with the ideal size being 1.5 ft³, using a single 3" diameter x 6½" long port. Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier.

Free-Air: The woofer can also be mounted in free air to a baffle board (infinite baffle, no enclosure). When mounted in free air, the power handling is reduced by 75% (to 125 watts).
