The Skar Audio Dual 10-inch package provides a fantastic middle ground between the massive dual 12s and the modest single 12. It delivers the same high-power philosophy—1,200 Watts RMS—using the potent RP-1200.1D Class D amplifier, but in a slightly smaller enclosure footprint suitable for smaller trunks or hatchbacks.

Helpful Comparison Insights

When comparing these subwoofer kit with amp options, the choice really boils down to three factors: size, power, and installation difficulty.

If raw power and volume are your priority, the Skar Audio Dual 12″ SDR Package (1,200W RMS) and the Skar Audio Dual 10″ SDR Package (1,200W RMS) are the top contenders. They require a lot of space but deliver earth-shaking bass. The Skar kits also win on wiring quality, offering Premium OFC 4-gauge kits.

For those who need to balance size and sound, the Skar Audio Single 12″ SDR Package (600W RMS) offers a fantastic compromise. It saves trunk space while still delivering strong, clean bass powered by an efficient Class D amp.

If minimal footprint and stealth are crucial, look exclusively at the powered options. The LUVUMVLT Slim Under Seat Subwoofer disappears completely under a seat, and the MTX Audio RT8PT Tube Sub fits neatly into corners, providing bass fill without dominating the cargo area.

Finally, the MTX 12-Inch Dual Subwoofer Bundle provides the best overall budget value for entering the world of dual 12-inch bass, even if the included amplifier and wiring are slightly less premium than the Skar systems.

Frequently Asked Questions About Subwoofer Kit with Amp

What makes an all-in-one subwoofer kit with amp a better choice than buying components separately?

The primary advantage of purchasing a complete subwoofer kit with amp is compatibility and convenience. The components—the subwoofer(s), enclosure, and amplifier—are professionally matched to ensure the amp delivers the correct power (RMS wattage) and impedance load to the subwoofers. This eliminates the risk of underpowering or overpowering the subwoofers, which can damage them. Additionally, these kits usually include the necessary wiring, saving you the time and hassle of sourcing compatible wires and fuses.

Do I need a separate wiring kit if I buy a subwoofer kit with amp?

In most cases, no. Nearly all comprehensive subwoofer kit with amp packages include an amplifier installation wiring kit (RCA cables, power wire, ground wire, remote turn-on wire, and fuse). However, pay close attention to the gauge of the included wire (e.g., 4 gauge or 8 gauge). For very high-power systems (over 1,000 watts RMS, like the Skar Audio kits), ensure the kit includes OFC (Oxygen-Free Copper) wire, as it provides better conductivity and is safer than CCA (Copper Clad Aluminum).

What is the difference between a loaded enclosure and a powered subwoofer?

A loaded enclosure (like the MTX or Skar dual kits) means the subwoofer driver(s) are already mounted inside the box, but the amplifier is external (a separate component). A powered subwoofer (like the MTX RT8PT tube or the LUVUMVLT slim sub) has the amplifier built directly into the enclosure. Powered subwoofers are simpler to install and save space, but loaded enclosures with separate amps usually offer higher power and better sound customization.

Will installing a subwoofer kit with amp drain my car battery?

Any car audio upgrade increases electrical demand. Reputable subwoofer kit with amp systems are designed to operate within the limits of a healthy vehicle electrical system. However, if your amp power exceeds 1,000 watts RMS, or if you plan on listening to music at maximum volume while the engine is off, you may experience battery drain. Installing an appropriate gauge power cable (4 gauge or larger for high power) directly to the battery and ensuring a strong ground connection minimizes this risk.

Should I choose a single 12-inch or dual 10-inch subwoofer kit?

This depends on the sound you prefer. A single 12-inch subwoofer generally moves more air, leading to deeper, lower-frequency bass (rumble), while taking up less space than a dual enclosure. Dual 10-inch subwoofers often have a faster, punchier response due to the smaller cone area of each driver, making them excellent for faster musical genres. If space allows, dual subs generally provide higher output (volume) than a single sub at the same power level.

Can I install a subwoofer kit with amp myself?

Yes, if you have basic wiring knowledge and tools. A subwoofer kit with amp is designed to simplify the installation process. The main steps involve running the power cable from the battery, running the RCA and remote turn-on wires from the head unit, and connecting the enclosure to the amp. If you are uncomfortable tapping into your vehicle’s wiring or don’t know how to set the amplifier’s gains properly, professional installation is recommended.
