- High mass solid pole piece aids heat dissipation
Who it fits
Good fit for
This subwoofer suits you if you have limited space in your vehicle or home theater. The 6.75-inch diameter fits where larger subs cannot go. The 2-ohm dual voice coil design helps you match your amplifier's output. You will appreciate the forced-air cooling if you plan to drive the sub hard. It is ideal for installers who need a reliable thin driver. The lightweight 4.75-pound build makes mounting easier. This option works well for those prioritizing fit and thermal management over massive excursion.
Who should skip it
You should look at another option if you need a subwoofer with a remote control or Bluetooth connectivity. The data does not mention a display or smart features. Skip this if you require a 4-ohm impedance only, as this model is strictly 2-ohm. It is not suitable for those who want a large 12-inch driver for maximum low-frequency displacement. The thin design may not satisfy listeners who prefer the deep, resonant room-filling sound of larger enclosures. It is also not for users who need a warranty extension beyond standard terms.
Verdict: The KICKER CompRT 6.75" 2-Ohm Subwoofer is a practical choice for tight installations requiring reliable heat management. Its compact size and dual voice coil design offer solid flexibility for custom builds.
Key specs for this subwoofer
Woofer Size: 6.75"
The cone diameter is 6.75 inches. This size fits in standard door speaker locations or small dash enclosures. You get bass from a compact driver. It suits vehicles with limited space. Compare this to larger 8-inch or 10-inch subwoofers that need bigger boxes. The smaller footprint allows installation where bigger subs cannot fit.
Impedance: 2 ohms (DVC)
The electrical resistance is 2 ohms with dual voice coils. This low impedance draws more power from your amplifier. It allows flexible wiring options for series or parallel setups. You can match it with amplifiers designed for low loads. Compare this to 4-ohm models that are easier to drive but may offer less output.
Weight: 4.75 pounds
The unit weighs 4.75 pounds. This is relatively light for a subwoofer. It reduces stress on mounting surfaces. You can install it in thinner panels or lighter enclosures. Compare this to heavier subs that require reinforced mounting. The lower weight aids in handling and installation for compact builds.
Dimensions: 12 x 10 x 9 inches
The package measures 12 by 10 by 9 inches. This defines the shipping and storage space needed. You can plan your garage or vehicle storage accordingly. Compare these dimensions to other subwoofer boxes. The compact packaging reflects the small physical size of the driver itself.

The solid construction and efficient cooling design support reliable operation in confined areas, making this a practical choice for users who need bass from a small driver.
Installation and Daily Use Notes
Setting up this KICKER CompRT 6.75" 2-Ohm Subwoofer requires attention to its dual voice coil design. The 2-ohm impedance allows for flexible wiring options. You can wire the coils in series or parallel to match your amplifier’s output. This flexibility is key for fitting the sub into various enclosures. The driver features forced-air cooling, which keeps the unit 20% cooler during operation. This heat management system supports reliable performance in tight spaces. The high mass pole piece aids in superior heat dissipation. You do not need a large enclosure to achieve true subwoofer performance. The thin profile fits into standard door locations or small dash mounts. Daily use involves connecting the sub to a compatible amplifier. Ensure your amplifier can handle a 2-ohm load. The black finish blends well with most vehicle interiors. Weighing 4.75 pounds, the unit is light but solid. Its compact dimensions of 12 by 10 by 9 inches make it easy to secure. The unique heat management ensures longevity even during extended listening sessions. You get powerful bass from a small driver. This setup is ideal for vehicles with limited space.

This subwoofer is built for practical, everyday use in compact environments.
Before You Buy This Subwoofer
You need an amplifier that supports 2-ohm loads. This subwoofer uses dual voice coils, which gives you wiring flexibility. You can configure the coils to match your specific amp requirements. Check your enclosure space carefully. The driver is thin, but you must account for its 6.75-inch diameter. Standard door locations often fit this size, but verify the cutout dimensions. The black finish matches most factory interiors. You will need mounting hardware if it is not included. Keep the ventilation clear. The listing highlights forced-air cooling and a solid pole piece for heat dissipation. Blocking airflow reduces reliability. This model fits well in small vehicles or tight dash enclosures. It complements larger subs if you want layered bass. Ensure your head unit or processor can drive the signal properly. This compact driver offers true subwoofer performance without taking up much room. It is a practical choice for space-constrained builds.
Check before you buy
- Verify your amplifier supports a 2-ohm stable load.
- Check enclosure cutout dimensions for the 6.75-inch diameter.
