Frequently Asked Questions About Best 12 Inch Car Subwoofer

What RMS power should I look for in a 12-inch car subwoofer?

RMS (Root Mean Square) power is the most critical specification, as it represents the continuous power the subwoofer can handle reliably. For a noticeable upgrade, look for a minimum of 300W RMS. High-performance 12-inch subwoofers often range from 600W to 1200W RMS. The higher the RMS, the louder and cleaner the sub can play for longer periods.

Are dual voice coil (DVC) subwoofers better than single voice coil (SVC)?

DVC subs, like the Skar SDR-12 D4, are inherently more flexible for wiring. They are not necessarily “better” in terms of sound quality, but they allow you to wire multiple subwoofers or match a single subwoofer to your amplifier’s optimal impedance (e.g., wiring a dual 4-ohm coil down to a 2-ohm load). This flexibility is crucial when dealing with high-current monoblock amplifiers.

Should I choose a sealed or a vented (ported) subwoofer enclosure?

This depends entirely on your listening preference. Sealed enclosures (like the MTX Terminator system) produce tighter, more accurate, and musical bass, making them great for rock and jazz. Vented or ported enclosures (like those found in Skar Audio packages) are more efficient, meaning they require less power to produce significantly louder bass, ideal for rap, EDM, and users prioritizing maximum volume.

Does the size of the magnet affect the performance of the best 12 inch car subwoofer?

Yes, the magnet structure (usually high flux ferrite) plays a vital role. A larger, heavier double-stacked magnet generally indicates a more powerful motor structure, which allows the subwoofer’s cone greater control over movement (excursion). This control minimizes distortion at high volumes and contributes to the subwoofer’s ability to handle high power ratings.

What is the purpose of the high-roll foam or rubber surround?

The surround (e.g., the ribbed Santoprene Surround on the KICKER CompR) connects the cone to the speaker basket. A high-roll surround allows the subwoofer cone to move further and faster (greater excursion). This increased movement is necessary to displace more air, resulting in deeper, louder bass without suffering damage or distortion.

Why do some complete subwoofer packages include an OFC wiring kit?

The wiring gauge and material are crucial for power delivery, especially for high-RMS subwoofers. OFC (Oxygen-Free Copper) is superior to CCA (Copper-Clad Aluminum) because it offers less resistance, allowing the amplifier to draw and deliver power much more efficiently. For systems rated 1000W RMS or higher, like the Skar Dual 12″ package, using OFC wiring ensures safety and prevents power loss.
