Who it fits
Good fit for
You should consider this subwoofer if you drive a vehicle with a full-size spare tire and value discretion. The hidden design protects against theft while keeping your trunk clear. It suits listeners who want significant bass impact without installing bulky boxes. The included wiring kit and remote make installation straightforward for beginners. If you need deep, clean low frequencies that stay out of sight, this unit meets your needs.
Who should skip it
Skip this option if you drive a compact car with a temporary spare or no spare tire at all. The unit requires a 15-inch to 17-inch full-size tire to mount properly. It is not suitable for those who want to maximize cargo volume, as it occupies the tire well. You should also look elsewhere if you prefer a subwoofer with Bluetooth connectivity or a digital display, as this model relies on analog controls and physical wiring only.
Verdict: The RockGhost V2 offers a clever, space-saving way to add powerful bass to your car audio system. It is an ideal choice for drivers with full-size spares who want hidden, high-output performance.
RockGhost V2 Key Specs Explained
Woofer Size: 11"
An 11-inch driver provides a larger surface area for moving air compared to smaller subs. This size helps produce deeper bass frequencies that you can feel. It balances physical footprint with acoustic output. You get substantial low-end response without needing a massive enclosure. This makes it suitable for compact vehicles where space is limited but you still want impactful sound.
Power Handling: 800 W peak, 200 W RMS
RMS power indicates the continuous wattage the amplifier can sustain. The 200W RMS rating suggests solid, clean output for daily listening. The 800W peak figure shows the maximum short-term burst capability. Higher RMS values generally mean louder volume without distortion. You can expect reliable performance under normal driving conditions without overheating the unit.
Amplifier Type: PWM MOSFET
This amplifier design uses Pulse Width Modulation and Metal-Oxide-Semiconductor Field-Effect Transistors. It offers high energy efficiency and reduced heat generation compared to older classes. The unit runs cooler, which improves longevity. It also draws less current from your vehicle battery. This efficiency is beneficial for installations where power management and thermal stability are priorities.
Connectivity: RCA, high-level inputs
RCA inputs allow direct connection to head units with pre-out jacks. High-level inputs let you connect to speakers that lack line outputs. This flexibility simplifies installation in various vehicle setups. You do not need an external line-out converter if your car lacks dedicated sub outputs. This dual connectivity ensures compatibility with most factory and aftermarket stereo systems.
Design and build details
According to the listing, the Rockville RockGhost V2 11 uses a cast aluminum build. This material choice supports a shallow mounting depth, allowing the unit to fit inside most spare tires. The enclosure measures 16.5 inches in length, 18.5 inches in width, and 8.66 inches in height. It weighs 20 pounds. The black finish blends with standard tire interiors. This compact footprint saves trunk space while keeping the subwoofer concealed from view. The design deters theft by hiding the equipment completely.
The layout includes a high-excursion 11-inch driver with flexible rubber surrounds. These surrounds help ensure reliable, vibration-free performance during playback. A PWM MOSFET amplifier drives the woofer, delivering 200 watts RMS and 800 watts peak power. This configuration aims for clean, musical sound without distortion at high volumes. The system is classified as a powered speaker for cars, meaning the amplifier is built into the enclosure.
Control placement prioritizes accessibility. A 20-foot remote dash control allows you to adjust gain, bass boost, and crossover settings from the driver’s seat. You can tweak the low-pass filter between 50Hz and 150Hz. The phase switch offers 0 or 180 degrees, and bass boost ranges from 0 to 12dB at 45Hz. This remote setup lets you tailor the audio to your vehicle’s acoustics without reaching into the trunk.
Setup and everyday use
Installation relies on a plug-and-play wiring kit included in the box. You connect power, ground, RCA cables, and high-level inputs. This allows the subwoofer to work with most factory head units or aftermarket receivers. The unit mounts directly to your spare tire. It fits tires with diameters of 15, 16, or 17 inches. The shallow depth ensures it stays hidden inside the tire well. This saves trunk space and keeps the bass source concealed from potential theft.
Daily use involves adjusting audio settings via the included 20-foot remote dash control. You can adjust gain, bass boost, and crossover frequency from your seat. The low-pass filter ranges from 50Hz to 150Hz. This lets you blend the subwoofer with your main speakers without muddying the midrange. You can also switch the phase between 0 and 180 degrees. This helps align the subwoofer’s output with your existing speakers for a tighter bass response.
The PWM MOSFET amplifier delivers 200W RMS and 800W peak power. This drives the 11-inch woofer with high excursion. You get deep, clean bass without distortion at moderate volumes. The flexible rubber surrounds help reduce vibration. The cast aluminum build supports this reliable performance. You do not need to open the trunk to make changes. The remote gives you full control over the sound profile while driving.
Before You Buy This Sub
You need to verify your spare tire dimensions before purchasing. The listing states it fits 15, 16, and 17-inch full-size spares. Measure your tire width and diameter carefully. A mismatch means the unit will not mount securely. You also should check your vehicle’s trunk clearance. Although it hides in the tire, the wiring kit requires routing. Ensure you have space for the remote control on the dash. The 20-foot cable helps, but clutter can still be an issue. This subwoofer is ideal if you value trunk space above all else. It suits drivers who want deep bass without sacrificing cargo room. If you need maximum volume for competitions, consider larger external enclosures. For daily driving and stealth, this fits well. Keep the mounting area clean to prevent corrosion. Regularly check the remote settings to maintain your preferred bass level. It is a unique solution, but compatibility is key.
Check before you buy
- Confirm your spare tire is 15 to 17 inches.
- Check trunk space for wiring and remote placement.
- Ensure your head unit has RCA or high-level inputs.
- Verify the remote control fits your dashboard comfortably.
