Who it fits
Good fit for
You should consider this subwoofer if you need deep bass without sacrificing cargo space. The thin down-firing design allows it to mount under seats or in trunks. The 2-ohm impedance suits amplifiers that support low-impedance loads. If you want a hidden installation that blends with your vehicle’s interior, this unit fits the bill. The passive radiator helps deliver intense bass without requiring a massive box.
Who should skip it
You might want to look elsewhere if you require a standard sealed or ported box. This unit is a specialized down-firing design that may not fit all vehicle layouts. The 2-ohm impedance limits compatibility with amplifiers that only support 4-ohm or higher loads. If you prefer a larger enclosure for maximum efficiency, this thin profile may not provide the same acoustic performance. The hidden driver design also means you cannot easily service the component.
Verdict: This subwoofer offers a space-saving solution for car audio enthusiasts who prioritize fitment. Its compact size and passive radiator design make it ideal for vehicles with limited cargo room.
Key Specs Explained
Woofer Size: 12"
A 12-inch driver moves more air than smaller units. This size typically delivers deeper, more impactful bass frequencies. You get substantial low-end response without requiring a massive box. This spec helps you compare it against smaller 8-inch or 10-inch subs. Choose this if you want pronounced rumble in a compact footprint.
Impedance: 2 ohms
This 2-ohm rating indicates lower electrical resistance. It allows the amplifier to deliver more power to the subwoofer. You must ensure your amplifier supports 2-ohm stability. This spec is critical for matching gear. Higher impedance subs draw less current. Select this if your amp handles low impedance loads for maximum output.
Enclosure Type: passive radiator
This design uses a driver without a voice coil to reproduce bass. It replaces a traditional port to reduce chuffing noises. The passive radiator moves in sympathy with the main woofer. This spec indicates a sealed-box approach with extended low-frequency response. It offers tight bass control. Compare this to ported boxes for different tonal characteristics.
Dimensions: 28.1 x 15.4 x 6.8 inches
These measurements define the physical footprint of the unit. The height allows for vertical mounting in tight spaces. The narrow width fits behind seats or in cargo areas. You can verify fitment in your vehicle before purchase. This spec helps you plan installation. Compare these dimensions to ensure it clears surrounding components in your specific car.
Design and Build Details
According to the listing, this unit features an extremely compact design with drivers hidden to blend into your vehicle’s makeup. The enclosure measures 28.1 inches in height, 15.4 inches in length, and 6.8 inches in width. It weighs 31 pounds. These dimensions allow it to mount easily in the cargo area without taking up valuable space. The black finish keeps the look clean and unobtrusive.
The build includes an internally braced enclosure. This structure provides ultimate protection for the internal components during transport or heavy use. The design utilizes a passive radiator to intensify bass output. This setup eliminates the need for a port, saving additional room inside the box. The forced-air cooling system keeps the driver 20% cooler than previous models. This thermal management increases reliability during long listening sessions.
You get a sealed, space-saving solution that prioritizes fitment. The thin profile ensures it does not interfere with rear seats or cargo. The hidden driver aesthetic maintains the original look of your interior. The 2-ohm impedance is not a physical design trait but an electrical specification that influences how you wire the amplifier. This subwoofer suits buyers who need deep bass without sacrificing trunk or cargo space. The sturdy construction suggests it can handle the vibrations of powerful low-frequency output while remaining secure in place.
Setup and Everyday Use Guide
Installation begins with positioning the subwoofer in your vehicle’s cargo area. The enclosure dimensions are 28.1 inches high, 15.4 inches long, and 6.8 inches wide. Its thin profile allows it to fit without occupying significant space. You can mount it easily, ensuring no space issues arise during placement. The design hides the drivers, helping the unit blend into your vehicle’s makeup. This compact form factor is ideal for preserving cargo room while adding audio performance.
Electrical setup requires an amplifier that supports 2-ohm impedance. The subwoofer’s 2-ohm rating means it draws more current than standard 4-ohm models. You must ensure your amplifier can handle this load safely. Proper power matching is essential for reliable operation. The forced-air cooling system keeps the driver 20% cooler than previous models. This thermal management increases reliability during extended listening sessions, reducing the risk of overheating.
Daily use involves enjoying intensified bass output. The ReFLEX passive woofer enhances low-frequency response without adding active complexity. The internally braced enclosure protects the drivers from vibration and impact. You benefit from a sturdy build that withstands road noise and vehicle movement. The black finish maintains a clean appearance inside your cargo space. No external controls or displays are listed, so you adjust levels through your head unit or amplifier. This straightforward setup focuses on pure audio performance and compact utility.
Before You Buy This Subwoofer
You need a compatible amplifier to drive this KICKER 48TRTP122. Its 2-ohm impedance requires an amp that can handle stable 2-ohm loads. Many standard amplifiers are designed for 4-ohm or higher stability. Using an incompatible amp may cause overheating or damage. Check your amplifier’s specifications carefully before purchasing. This subwoofer fits into the compact category of Subwoofers & Home Speakers. It is ideal for vehicles where space is limited. Unlike larger boxed subs, it mounts in cargo areas. You should ensure your vehicle has enough vertical clearance for the 28.1-inch height. Regular upkeep involves keeping the forced-air cooling vents clear. Dust accumulation can reduce reliability. This model is not for stationary home theater use. It is built for automotive environments. Verify your mounting location can support the 31-pound weight. The passive radiator design enhances bass without a traditional port. This means you do not need to worry about port noise. However, the enclosure is rigid. Ensure the mounting surface is flat and secure.
Check before you buy
- Verify your amplifier supports stable 2-ohm loads.
- Check vehicle clearance for 28.1-inch height.
- Ensure cargo area supports 31-pound weight.
- Confirm mounting surface is flat and secure.
