Kicker Comp RT 12ft Subwoofer Enclosure Package + Amp & Wire Kit

Our review of the Kicker Comp RT 12' Subwoofer Enclosure Package finds it best for drivers who want deep, punchy bass from a space-saving solution. The bundle pairs the thin down-firing 48TRTP122 12' enclosure with a 400-watt mono Class D amp and a full 6AWG wiring kit, delivering more usable bass than expected from such a compact install. Installers and DIYers will appreciate the enclosure's low profile and the amp's adjustable controls, making it a practical choice for sedans, trucks with limited trunk space, or anyone who wants tight, controlled low end without a massive box.

Key Features

• Thin down-firing enclosure: The TRTP enclosure hides the driver and radiator in a very compact footprint so it integrates cleanly into the vehicle and saves cargo space.
• 12' woofer with passive radiator: The paired passive radiator extends low-frequency output and helps the packaged sub deliver fuller bass than a bare 12' in a small box.
• 400-watt mono Class D amplifier: The CXA4001 provides solid power with a variable 12dB crossover and KickEQ bass boost to tailor the sub's output to listening preference.
• Complete 6AWG wiring kit: The VK6 kit supplies hyper-flex power, ground and turn-on cables plus interconnects so the package is installation-ready.
• Adjustable filters and boost: The amp's 24dB subsonic filter and KickEQ control let users tighten bass and protect the driver for cleaner low-frequency performance.

Who It's For

This package is ideal for vehicle owners who need a low-profile subwoofer solution that still produces serious bass. It suits drivers with limited trunk height or those who prefer an integrated look where the speaker becomes part of the vehicle's makeup.

It is less appropriate for car audio enthusiasts seeking maximum SPL or very large concert-level bass, since the thin enclosure trades absolute cone excursion for compactness. Buyers wanting multiple large subs or custom ported enclosures should look at full-sized sub boxes instead.

Pros & Cons

Pros

• Great sound quality for the size thanks to the passive radiator and tuned enclosure design.
• Ease of installation with the included 6AWG wiring kit and a compact enclosure that fits tight spaces.
• Good value for money because the bundle includes the amp, wiring kit, pry tool and a coaster for a complete setup.

Cons

• Build quality receives mixed feedback from some customers, so buyers should inspect mounting and finish if appearance is critical.
• Not intended for maximum SPL or extreme bass lovers who need larger or multiple subs.
