The Rockville DK58 Package is a complete bass system designed for car audio enthusiasts who want a straightforward upgrade without the guesswork of matching components. It pairs two 8-inch K5 subwoofers in a pre-loaded ported enclosure with a Rockville dB11 mono amplifier and an 8-gauge wiring kit. This package is ideal for drivers of sedans, trucks, or SUVs who want a noticeable improvement in low-end response and are comfortable with a DIY installation.

The core of this system is the dual 8-inch subwoofers, each rated at 800W peak (200W RMS) for a combined 1600W peak (400W RMS). The 2-ohm impedance matches the amplifier's output, which delivers 1400W peak (350W RMS) at 2 ohms. This setup produces a rich, deep bass that enhances music with punchy lows. The ported enclosure is tuned to 37 Hz with 0.80 cubic feet of air space per sub, which is a common tuning for a balance of output and sound quality.

Build quality is a highlight: the enclosure is made from 3/4-inch MDF, bonded, stapled, and braced for rigidity. The subwoofers feature 1.5-inch 4-layer aluminum voice coils wound with Japanese OFC copper wire, and the non-pressed paper cones have blue stitching for reinforcement. Gold-plated push terminals ensure secure connections. The included dB11 amplifier is Class-D, which is efficient and compact, and it features a bass remote, adjustable crossover, and MOSFET power supply for reliable performance.

One limitation is the power handling: 400W RMS is moderate and may not satisfy those seeking extreme volume or SPL competition levels. Also, the enclosure is sizable, so measure your trunk or cargo area before purchase. If your head unit lacks RCA outputs, you'll need to consider an adapter or a different amp with high-level inputs. The included wiring kit is 8-gauge, which is adequate for this power level but may need upgrading if you later add more powerful components.

Verdict: The Rockville DK58 Package offers a convenient, all-in-one solution for adding solid bass to your vehicle. The strongest reason to buy is the complete package that simplifies setup and delivers good performance for the price. The main reason to hesitate is if you need extreme output or have space constraints. If you're a basshead seeking maximum SPL, consider larger subs or more powerful amps. For most listeners who want a clean, impactful bass upgrade, this package is a practical choice.

Dual 8-inch Subwoofers: Two 8-inch K5 subwoofers provide a combined peak power of 1600W (400W RMS) with 2-ohm impedance. This configuration delivers a balanced bass response that suits a wide range of music, from rock to hip-hop, and is ideal for those who want noticeable low-end without overwhelming the cabin.

Ported Enclosure Tuned to 37 Hz: The enclosure is computer-designed with vents and a 15% angled alignment to optimize bass projection. Tuning at 37 Hz with 0.80 cu ft air space per sub ensures efficient output in the deep bass region, making it great for reproducing sub-bass frequencies in modern music and movies.

Class-D Amplifier (dB11): The included amplifier is compact and efficient, delivering 1400W peak (350W RMS) at 2 ohms. Class-D technology means less heat and power draw, and the MOSFET power supply ensures stable performance. The bass remote lets you adjust the bass level from the driver's seat, adding convenience.

Durable Construction: The subwoofers feature 1.5-inch 4-layer aluminum voice coils wound with Japanese OFC copper wire, which aids heat dissipation and reliability. The non-pressed paper cones with blue stitching reinforcement resist warping, and the MDF enclosure is bonded, stapled, and braced for rigidity, reducing unwanted vibrations.

Complete Installation Kit: The package includes an 8-gauge wiring kit with copper RCA cables, power and ground cables, and necessary accessories. This saves you time and money, as you won't need to purchase separate wiring, and it simplifies the installation process for a DIY setup.

Best For: The Rockville DK58 Package is best for car audio enthusiasts who want a complete, ready-to-install bass system with balanced output. It's ideal for those driving sedans, trucks, or SUVs who have basic DIY skills and want to upgrade their factory stereo's bass without the complexity of choosing separate components.

Consider Alternatives If: If you need extreme SPL for competitions or if you have a very small vehicle with limited cargo space, this package may not be suitable. Also, if your existing head unit lacks RCA preamp outputs, you'll need to factor in an adapter or choose a different system with high-level inputs.

Setup and Daily Use: The package is designed for straightforward installation: mount the amp, connect the wiring kit to the battery and head unit, and place the enclosure in your trunk or cargo area. The included bass remote allows you to adjust bass levels on the fly, which is convenient for different music genres.

Maintenance Requirements: Minimal maintenance is required. Periodically check the wiring connections to ensure they are secure, and avoid overdriving the system to prevent damage to the subs or amp. Keep the enclosure and amp clean to prevent dust buildup, which can affect performance.

What Sets It Apart: The main differentiator is the all-in-one nature of this package. Instead of researching and matching a subwoofer, enclosure, amp, and wiring kit, you get a system that is pre-matched and tested to work together. This reduces the risk of incompatibility and simplifies the buying process.

Installation Overview: The Rockville DK58 Package is designed for DIY installation. The enclosure comes pre-loaded with the subwoofers, so you only need to mount the amplifier, run the power and ground cables from the battery, and connect the RCA cables from your head unit. The included 8-gauge wiring kit provides the necessary cables and accessories.

Amplifier Placement: The dB11 amp is compact and can be mounted under a seat or in the trunk. Ensure it has adequate ventilation to prevent overheating. The bass remote can be mounted near the driver for easy access.

Connection Tips: Use the gold-plated push terminals on the enclosure for a secure connection. When connecting the amp, make sure to use the correct gauge wire and secure all connections to avoid shorts. If your head unit lacks RCA outputs, you may need a line output converter.

Ongoing Care: Periodically inspect the wiring for wear or corrosion, and check that the enclosure's screws and terminals remain tight. Avoid setting the gain too high, as this can cause distortion and damage the subwoofers. With proper care, this system should provide years of reliable bass.
