The SoundQubed HDS3.3 12" 1500W RMS DVC Subwoofer D2/D4 is a powerful 12" car audio subwoofer built for customers who want serious bass output, real power handling, and a strong daily-driver subwoofer platform. This listing includes both dual 2 ohm and dual 4 ohm voice coil options, so you can choose the version that best matches your amplifier, wiring plan, and final impedance goal.

The HDS3.3 12" is rated at 1500 watts RMS and 3000 watts max, making it a strong choice for loud daily builds, trunk systems, custom subwoofer boxes, and car audio setups that need more output than a basic 12" subwoofer can provide. With a 3" dual voice coil design, this subwoofer is made for real amplifier power while still keeping the popular 12" size that works in a wide range of vehicles and enclosure layouts.

A 12" subwoofer is one of the most popular choices in car audio because it gives you a strong balance of low-end bass, punch, enclosure flexibility, and output. The SoundQubed HDS3.3 12" is a great option when you want serious bass without jumping into a larger 15" or 18" setup.

Choosing the correct voice coil option matters. Choose the D2 version if your amplifier and subwoofer wiring plan call for dual 2 ohm voice coils. Choose the D4 version if your amplifier and wiring plan call for dual 4 ohm voice coils. If you are not sure which one you need, read our Dual 2 Ohm vs Dual 4 Ohm Subwoofer Guide before ordering.

Important Voice Coil Notice:

This listing is for one SoundQubed HDS3.3 12" subwoofer with selectable voice coil options. Please choose either D2 or D4 before checkout. D2 means dual 2 ohm voice coils. D4 means dual 4 ohm voice coils. The right choice depends on your amplifier, the number of subwoofers you are using, and your target final ohm load.

For a single subwoofer setup, a dual 2 ohm subwoofer is commonly used when the goal is a 1 ohm final load. A dual 4 ohm subwoofer is commonly used when the goal is a 2 ohm final load. Always verify your amplifier’s minimum stable impedance before wiring the subwoofer. Our Subwoofer Wiring Diagrams and Ohm Load Guide can help you understand series wiring, parallel wiring, and final impedance before you install.

Recommended Use:

The SoundQubed HDS3.3 12" subwoofer is recommended for car audio customers who want a strong daily bass setup, a loud trunk build, or a custom enclosure system with real low-end output. It is a strong middle ground between smaller compact subs and larger high-output 15" or 18" builds.

For best results, use this subwoofer with a properly matched monoblock amplifier, quality speaker wire, correct impedance wiring, and an enclosure built around the subwoofer and vehicle. The box matters a lot with any 12" subwoofer. If you are still planning the enclosure side of the build, read our Subwoofer Box Guide or shop our Subwoofer Boxes & Enclosures.

Build the Full System Correctly:

A subwoofer like the HDS3.3 12" performs best when the whole system is matched correctly. The amplifier, enclosure, wiring, final ohm load, and electrical support all work together. If one part is wrong, the system may lose output, create heat, drop voltage, or fail to perform the way it should.
