XT Audio 15" SPL Subwoofer – 7500W, Dual Voice Coil, 2 Ohm

The XT Audio 15" SPL subwoofer is a big-power, high-output 15-inch car subwoofer built for enthusiasts who want to move serious air and turn heads at every stoplight. Rated to handle up to 7,500 watts on a dual voice coil, 2-ohm design, this subwoofer is engineered for deep, aggressive, chest-hitting bass — the kind of low end you feel as much as you hear. If your goal is loud, competition-style output from a single subwoofer, the XT Audio 15 is made for the job.

Built to move air and hit hard

A 15-inch cone displaces a lot of air, and that is the foundation of deep, powerful bass. Paired with heavy-duty power handling of up to 7,500 watts, this XT Audio subwoofer is designed for SPL builds, daily "loud" systems, and anyone who wants their music to hit with authority. The larger cone area, combined with the high power rating, means it can produce the low frequencies that smaller subwoofers simply cannot reproduce with the same impact.

Dual voice coil flexibility

The dual voice coil, 2-ohm design gives you wiring flexibility so you can match the subwoofer to your amplifier for maximum output. A dual voice coil sub can be wired in series or parallel, letting you land on the impedance your monoblock amplifier likes best. That flexibility is a big reason SPL builders favor dual voice coil subs: you get more control over the final load, and therefore more control over how much clean power reaches the coil.

Specifications

Getting the most from your XT Audio 15

To get the output this subwoofer is capable of, three things matter: a strong monoblock amplifier, a properly built enclosure, and a healthy electrical system. Pair it with a high-current amplifier that can deliver clean power at your target impedance, and build a sturdy enclosure — a ported box tuned for output is a popular choice for a sub like this, though a large sealed box can deliver a tighter response. Because a 7,500-watt-class subwoofer can pull heavy current, plan on upgraded power wiring and, in most cases, an upgraded battery or a big-three electrical upgrade so your voltage stays stable when the bass hits.

Why choose the XT Audio 15" subwoofer

XT Audio focuses on high-output, SPL-oriented gear, and this 15-inch subwoofer is a centerpiece for a loud build. With big power handling, a flexible dual voice coil, and the air-moving advantage of a 15-inch cone, it gives value-minded enthusiasts a path to serious bass without stepping up to boutique competition pricing. Build it right and it will give you the deep, aggressive low end you are after.

Frequently asked questions

How much power does the XT Audio 15 need?

It handles up to 7,500 watts, so a high-current monoblock amplifier that can deliver strong, clean power at your wired impedance is the right match. You do not have to feed it the maximum to enjoy it, but more clean power (with gains set correctly) unlocks more of its output.

How do I wire a dual voice coil 2-ohm subwoofer?

With dual 2-ohm coils you can wire the two coils in parallel for a lower final impedance or in series for a higher one, depending on what your amplifier is stable at. Choose the configuration that lets your amp deliver its rated power safely.

What kind of box should I use?

For maximum SPL and output, a ported enclosure tuned to your target frequency is the usual choice for a subwoofer like this. If you prefer a tighter, more controlled sound, a large sealed box works too. Build it strong — high-power subs need a rigid, well-braced enclosure.

Do I need to upgrade my car's electrical system?

For a subwoofer in this power class, yes — most builds benefit from upgraded (large-gauge) power and ground wiring, a strong battery, and often a "big three" upgrade or extra battery to keep voltage stable under heavy bass demand.

Additional system planning notes

For the XT Audio 15" SPL Subwoofer – 7500W, Dual Voice Coil, 2 Ohm, the original product description above remains the primary product-specific content. Before installation, also verify voice-coil configuration, final wired impedance, amplifier compatibility, enclosure requirements, mounting depth and available vehicle space. A clean car audio build depends on matching the component to the complete system rather than relying on a single specification. Plan mounting, wiring, electrical support and tuning before the vehicle is disassembled, and keep model-specific manufacturer guidance as the final reference for any specification that is not stated here. After installation, test at conservative levels, confirm that every channel and connection operates normally, and then make tuning changes one at a time. This method helps protect the equipment, simplifies troubleshooting and makes it easier to achieve consistent performance in daily use.
