KICKER 10 Inch Comp RT Thin Woofer Includes Two 48CWRT102 2 Virtual 2 ohm Package
Quick take
This bundle pairs two KICKER 10-inch CompRT thin marine subwoofers (48CWRT102) designed for compact installations like under-seat truck setups or behind the seat in an off-road vehicle. It’s built for waterproof outdoor use and comes with crossover, wiring, and remote bass control components, so you are not starting from zero. The main thing to confirm before buying is that your amp and wiring match the bundle’s impedance and mono setup requirements.
Pros and cons
Pros
- Thin/shallow design with mounting depth under 5 inches (useful when space is limited).
- Weatherproof and rated as waterproof, which is a strong fit for marine and harsh outdoor conditions.
- Dual 2-ohm voice coils and a bundle intended for impedance-flexible installation.
- Includes control and signal conditioning components (variable crossover/bass boost features on the compatible mono amp setup).
Cons
- Works best with the right mono amp and correct impedance wiring, so it is not a universal drop-in.
- Deep “subwoofer wall” style output expectations may not match a shallow driver, even though it is designed for full-size sound.
- Optional accessories like subwoofer grilles and remote bass controllers are mentioned as available, so verify you have what your install needs.
What buyers think
Buyer-review evidence is too limited to draw a reliable pattern about day-to-day performance or long-term reliability from verified customer snippets. With that said, the product is clearly positioned as a compact, waterproof marine/off-road subwoofer solution, so the most practical way to evaluate it is against its stated specs, mounting constraints, and amp compatibility.
What this bundle is for
The KICKER CompRT “thin” 10-inch subwoofer line is intended to bring deeper low-end to installs where enclosure space is tight. This specific package includes two 10-inch CompRT thin subs with dual 2-ohm configurations, plus additional components to support integration (crossover/controls and cabling).
If you are building a marine or off-road audio system and you need something waterproof that can fit in a shallow location, this bundle is aimed directly at that problem.
Key specs that matter for buying
Shallow mounting and installation fit
The CompRT subs are described as less than 5 inches deep, which is a major deciding factor for “under the seat,” “behind the seat,” and other tight footprint installs. The specified mounting depth is about 3-7/16 inches.
Impedance, voice coils, and wiring
Each 48CWRT102 sub is listed as DVC with dual 2-ohm voice coils, and the package is described with an overall 2-ohm configuration. Because impedance and coil wiring can change the load seen by your amplifier, your install planning should focus on matching the bundle’s intended load to your mono amp’s supported impedance range.
Power and frequency range
Stated power handling includes 400 watts RMS (peak handling is listed as 800 watts). The frequency response is listed around 25 Hz to 500 Hz, which is typical of subwoofer behavior, but real-world results will still depend heavily on your enclosure volume and how you tune the crossover.
Waterproof, outdoor-ready design
The bundle is positioned as waterproof, and it uses a forced-air cooling concept intended to help manage heat in demanding use. For marine buyers, this matters because saltwater environments and sun exposure are harder on electronics and drivers than most sealed garage setups.
Bundle components and how control usually works
Alongside the two subwoofers, the bundle includes a variable crossover feature with KickEQ bass boost and a subsonic filter concept on compatible mono amps. It also includes cables for power, ground, and turn-on, and it mentions remote bass control availability.
In practical terms, this means the system is meant to be tuned for bass output without requiring you to guess where the low-frequency roll-off should start. That can be especially useful if you are trying to minimize distortion or keep the bass tight at higher listening levels.
Pros and cons, in real-world terms
When it’s a great match
- You need a shallow marine subwoofer that can fit in a compact enclosure or limited mounting spot.
- You want a waterproof driver for outdoor use, including boating or wet/dirty trails.
- You prefer a bundle approach, with crossover/control features and supporting cables included.
When you should look elsewhere
- You do not have a compatible mono amplifier or you are not comfortable verifying wiring for the correct impedance load.
- You are chasing maximum “car audio competition” output from a very small enclosure. A thin design is a tradeoff, even when engineered to sound strong.
- You need a specific accessory set (grilles, specific remote controller) and you want to avoid any uncertainty. Check what is included versus what is only listed as optional.
Verdict
The KICKER 10-inch CompRT thin woofer bundle is a solid choice if your priority is fitting a waterproof sub into a tight space while still getting tunable, bass-focused control. The decision hinge is less about hype and more about compatibility: confirm your amp can handle the bundle’s impedance approach, and plan your enclosure/enclosure mounting to take advantage of the thin-driver design.

FAQ
Is this KICKER bundle intended for marine use?
Yes, it is positioned as a waterproof marine/off-road subwoofer option. That makes it a better fit than typical non-weatherproof sub setups for boats or wet outdoor environments.
How deep do these subs mount?
The design is described as less than 5 inches deep, with a stated mounting depth around 3-7/16 inches, which is why it is often chosen for under-seat and other shallow installs.
What impedance and wiring should I plan for?
Each woofer uses dual 2-ohm voice coils, and the bundle is described with a 2-ohm configuration. You should verify your amplifier’s mono impedance compatibility and wire the voice coils to match the intended load.
Do I need a mono amplifier?
The crossover/control features are described in the context of mono amps (including subsonic filtering and variable bass boost). If your system uses a different amp setup, confirm compatibility before purchasing.
Is the sound “thin” because these are shallow subs?
The model is designed specifically to avoid the “thin sound” expectation that some people associate with shallow drivers, but enclosure size and tuning still affect results. If you have the space for larger, deeper subs, output may differ.

The Rockford Fosgate M2D4-12SB Color Optix is a 12-inch dual-voice-coil (DVC) 4-ohm marine subwoofer built for small sealed enclosures, with integrated RGB LED lighting you can control using the Color Optix system. It supports 400W RMS (1600W peak), is switchable between 2 and 8 ohms via VersaSwitch, and carries IP67 protection for water spray and UV resistance. The main tradeoff is that it is part of a Color Optix ecosystem, so you’ll want to plan for compatible controller/app accessories if you want full LED customization.
