Rockville DK58 Dual 8ft 1600W Loaded Subwoofer Enclosure - Deep Bass

In this review the Rockville DK58 Package is evaluated for drivers who want a compact, plug-and-play way to add low-end impact to a factory or aftermarket car system. The bottom line: this package pairs dual 8' K5 subwoofers in a well-built 3/4' MDF enclosure with a compact Class-D dB11 amplifier to deliver deep, room-filling bass without taking excessive cargo space. It is best for listeners who want strong, tunable low frequencies and an installer-friendly kit that includes most wiring and accessories.

Key Features

• Deep, powerful bass: Dual 8' K5 subwoofers produce 1600W peak (400W RMS) at 2-ohm impedance, giving pronounced low-end punch for music and bass-heavy tracks.
• High-quality enclosure: The bonded, stapled and braced 3/4' MDF box with computer-designed vents and 15% angled alignment improves bass projection and reduces unwanted resonance.
• Tuned response: The enclosure is tuned to 37 Hz with 0.80 cu ft air space per sub to deliver tight, musical low frequencies rather than muddy boom.
• Compact, efficient amplifier: The Rockville dB11 Class-D amp offers 1400W peak / 350W RMS at 2 ohm with a MOSFET power supply and a bass remote for on-the-fly level control.
• Durable driver construction: 1.5' 4-layer aluminum voice coils with Japanese OFC copper wire and reinforced non-pressed paper cones improve reliability under power.
• Complete installation kit: The included 8-gauge wiring kit with copper RCA cables, power and ground leads, and accessories speeds installation in sedans, trucks, or SUVs.

Who It's For

This package suits car audio enthusiasts who need a compact, self-contained solution that adds real low-end without a large enclosure. It is ideal for people upgrading a stock stereo who want a unit that arrives mostly ready to connect and tune with the included amp and wiring kit.

Those who need extremely deep extension below 30 Hz, multiple sub configurations, or custom enclosures for competition-level SPL may look elsewhere; this kit balances size and output rather than chasing the lowest octave or contest peak levels.

Pros & Cons

Pros

• Strong, defined low-end from dual 8' drivers that enhance music and movies.
• Sturdy 3/4' MDF enclosure with bracing and tuned vents for controlled bass projection.
• Compact Class-D amp with bass remote and adjustable crossover makes tuning simple.
• Includes an 8-gauge wiring kit and hardware for faster installation in most vehicles.

Cons

• Not aimed at extreme low-frequency extension below the tuned 37 Hz, so very deep sub-bass may be limited.
• Some customers noted wiring and functionality concerns, so careful installation and inspection of supplied cables is advisable.
