About the Pioneer TS-A120D4

Bob Bihlmayer

Bring your tunes alive

I don't think it's any exaggeration to say that a good sub will make your car's sound system come alive, and Pioneer made their A-Series subs to give you the deep low-frequency punch that you want. Their TS-A120D4 12" subwoofer handles up to 500 watts RMS while pumping out loud, clean bass. This sub features an injection-molded polypropylene cone that's impregnated with glass fibers and mica for exceptional precision and strength. A butyl rubber surround supports the woofer during cone excursion so you'll get accurate, hard-hitting bass notes even when the music's turned up loud.

Enhance your ride

This potent Pioneer sub will bring out all the punch and power in your music by filling in the lowest frequencies of the sound spectrum. Its dual 4-ohm voice coils give you more wiring options when setting up your system. Throw one or two of these subs in your daily ride, power them up with a nice amp, and you'll understand what the fuss is all about — whatever you listen to, great bass will make it sound much, much better.

Product Research

Features

Woofer Cone: Pioneer uses Glass Fiber and Mica reinforced injection molded polypropylene (IMPP) for the cone, making it more rigid than polypropylene alone.

Dual 4Ω Voice Coils: This woofer features two 4Ω voice coils, offering wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 2Ω load; when 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.

Measurements: When mounting the woofer without the trim ring, the dimensions change as follows:

  • Mounting Height: 0.53"
  • Flange Height: 0.168"
  • Frame Diameter: 12.235"

Q
How big of an Amp would I need to run 3 of these?

Tripling up on the Pioneer TS-A120D4 12" subs is a great idea for impressive bass output, Brysen! Since the wiring can get complicated with DVC 4-ohm speakers, the first link below is a handy wiring diagram you will want to use that will show around 2.7-ohms at your mono amp terminals. With a total RMS of 1500-watts with the triple setup, we can use a powerful amp for maximum performance. For me, the ideal choice is the JL Audio HD series HD1200/1 in the second link below. This amp has a regulated output of 1200-watts RMS from 1.5-4 ohms. This means you will get that 1200-watts at your roughly 2.7-ohm load in your custom setup. The Kicker 46CXA1800.1T in the third link below is also a major contender, though potentially too powerful for the three Pioneer's so you would have to make sure you set your amp up properly to avoid damage. We have the speakers and amps in stock and ready to ship! https://images.crutchfieldonline.com/ca/learningcenter/car/subwoofer_wiring/3DVC_4-ohm_mono.jpg https://www.crutchfield.com/p_136HD1200/JL-Audio-HD-Series-HD1200-1.html https://www.crutchfield.com/p_20646CX18T/Kicker-46CXA1800-1T.html?tp=35834

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

It should work just fine. You just have to wire the dual voice coils in parallel to make the speaker a 2ohm load and you should be good to go.
