Practical Buying Insights: Choosing Your Subwoofer and Amp Kit

Selecting the right subwoofer and amp kit boils down to balancing three key factors: space, power, and price.

1. Power vs. Size: The biggest differentiator is the size of the drivers (8-inch, 10-inch, 12-inch) and the RMS power. If you have minimal space (trucks, small hatchbacks), consider the BOSS BASS8K (under-seat) or the Skar Single 8-inch kit (350W RMS). If you can sacrifice a large chunk of trunk space and crave earth-shaking bass, the Skar Dual 12-inch kit (1,200W RMS with OFC wire) is the top choice.

2. Wiring Matters: Pay close attention to the included wiring. For kits under 500W RMS, an 8-gauge kit is usually sufficient. However, for systems rated 600W RMS and above, like the Skar 12-inch single or dual setups, a 4-gauge wiring kit is crucial to prevent voltage drop and ensure the amplifier performs at its advertised specifications. Even better is OFC (Oxygen-Free Copper) wire for cleaner power delivery, as seen in the high-end Skar dual kit.

3. Enclosure Design: You saw both 10-inch and 12-inch options. Dual 10-inch kits (like BELVA’s 500W RMS) tend to be more musical and responsive, offering a tighter bass note. Dual 12-inch kits offer deeper extension and significantly more volume. Vented (ported) enclosures are used in nearly all these packages to boost output and volume dramatically.

Final Verdict

The best subwoofer and amp kit depends entirely on your vehicle and audio goals.

For The Enthusiast Who Demands Maximum Power: The Skar Audio Dual 12″ Complete 2,400 Watt SDR Series Subwoofer Bass Package is the undisputed champion. Its 1,200W RMS rating and premium OFC wiring make it a true powerhouse built for volume and deep frequency response.

For The Daily Driver Seeking Best Value: The Skar Audio Single 12″ Complete 1,200 Watt SDR Series Subwoofer Bass Package hits the sweet spot. It offers a powerful 600W RMS output from a manageable single 12-inch enclosure, balancing power, size, and cost perfectly.

For The Space-Constrained Driver: If keeping trunk space is essential, the BOSS Audio Systems BASS8K low-profile unit or the Skar Audio Single 8″ kit provides significant bass improvements without the usual bulk associated with serious car audio.

Common Questions About Subwoofer and Amp Kit

What does “RMS” power mean, and how important is it when buying a subwoofer and amp kit?

RMS stands for Root Mean Square. It is the most important power rating because it represents the continuous, steady power the amplifier can safely deliver to the speakers, and the continuous power the subwoofer can handle without damage. Always match the amplifier’s RMS output rating to the subwoofer’s RMS input rating for the best performance and longevity. Peak power ratings (P.M.P.O.) are usually exaggerated and not reliable for comparisons.

Is an 8-gauge or 4-gauge wiring kit better for my new system?

Generally, a 4-gauge wiring kit is always preferable, especially when you install a high-performance subwoofer and amp kit. 8-gauge wire is suitable for kits with an RMS power output of 500 watts or less. However, for anything 600 watts and above, 4-gauge wire is necessary to properly handle the high current demands, reducing voltage drop and ensuring the amplifier runs efficiently and without overheating.

Can I install a subwoofer and amp kit myself, or should I hire a professional?

Many manufacturers design a modern subwoofer and amp kit for DIY installation, especially those that include comprehensive wiring kits and instructions. If you are comfortable working with basic wiring, running cables through your vehicle, and connecting to the car battery and stereo signal, you can likely handle the installation. However, if you are unsure about electrical connections or splicing into factory stereo wiring (especially for high-level inputs), hiring a certified installer is recommended to avoid electrical issues or damaging your new equipment.

What is the difference between a ported (vented) and sealed subwoofer enclosure?

Ported (or vented) enclosures, which are common in these kits, include a tuned port or vent. This design dramatically increases the overall volume and efficiency of the bass output, making the bass louder and deeper, especially at lower frequencies. Sealed enclosures are airtight and produce tighter, more accurate, and musical bass, but generally require more power (a higher RMS amplifier) to achieve the same volume level.

Will adding a subwoofer and amp kit drain my car battery?

A correctly installed subwoofer and amp kit should not drain your car battery excessively, provided your vehicle’s alternator is healthy. Modern Class D amplifiers are highly efficient. However, if you play the system at extremely high volumes while the engine is off for extended periods, you could drain the battery. High-power systems (1,000W+ RMS) may require upgrading your vehicle’s “Big 3” wiring or installing a dedicated secondary battery to ensure stable voltage.

Do I need a bass remote (bass knob) for my new subwoofer and amp kit?

A bass remote, often called a bass knob, is a very useful addition. It allows you to adjust the bass level quickly and independently of your main volume control. This is incredibly practical for switching between different music genres or compensating for varying road noise levels without having to access the amplifier in the trunk to change the gain setting. Many quality kits, like the Rockville packages, include one automatically.
