RockGhost V2 800W Powered 11ft Car Subwoofer - Hidden Spare Tire Bass

In this review the RockGhost V2 is presented as a practical, space-saving powered subwoofer for drivers who want deeper bass without losing trunk room. The single biggest reason to buy is its hidden spare tire design, which mounts on top of a full-size spare to keep the subwoofer concealed while delivering punchy low end. Reviewers will appreciate that setup is straightforward and that the unit balances power and install convenience for everyday car audio upgrades.

Key Features

• Hidden spare tire mount: Installs on top of 15'/16'/17' full-size spare tires to preserve trunk space and reduce the risk of theft by staying out of sight.
• 800W peak performance: Provides strong, deep bass with 200W RMS and an 11' high-excursion driver for clean low-frequency output without obvious distortion.
• Plug-and-play installation: Includes a complete wiring kit with power, ground, RCA and high-level inputs so most installs are quick and tidy.
• Remote dash control: A 20ft wired remote lets the driver adjust gain, bass boost and crossover from the dash for real-time tuning.
• Adjustable audio settings: Low-pass filter (50Hz-150Hz), phase switch (0/180) and 0-12dB bass boost at 45Hz let users tailor the output to their vehicle and music.
• Durable construction: Cast aluminum shallow-mount design and flexible rubber surround reduce vibration transfer while fitting into tight spare wells.

Who It's For

The RockGhost V2 suits car audio enthusiasts who need meaningful low-end impact but do not want to lose trunk space or advertise aftermarket gear. It is especially appropriate for owners of vehicles with full-size 15', 16' or 17' spare tires who want a concealed solution and a quick install using the included wiring kit.

Those who should look elsewhere include drivers without a full-size spare tire or anyone seeking ultra-high output beyond an 800W peak class enclosure; likewise, vehicles that require a custom enclosure shape might be better served by a dedicated external box or a larger pro install.

Pros & Cons

Pros

• Great sound quality for the form factor, delivering deep bass that complements multiple music genres.
• Easy installation with included wiring kit and a 20ft remote for convenient tuning.
• Hidden mounting design saves trunk space and deters theft compared with visible enclosures.
• Adjustable crossover, phase and bass boost allow precise tuning to vehicle acoustics.

Cons

• Requires a full-size spare tire (15'/16'/17') so it is not suitable for cars with space-saver spares or no spare at all.
• While powerful for its size, those seeking extreme SPL competition levels will need a larger external subwoofer.
