BOSS Audio Systems R1100MK Car Amplifier and 8 Gauge Wiring Kit – 1100 Watts Max Power, 2-4 Ohm Stable, Class A/B, Monoblock, Mosfet Power Supply, Remote Subwoofer Control

Unlike the other options reviewed, this BOSS kit is not a loaded enclosure bundle; it is a standalone amplifier and 8 gauge wiring kit. This product is ideal for readers who already own a quality passive subwoofer enclosure and simply need a powerful amplifier and the necessary cables to drive it. The R1100MK Class A/B monoblock amp provides up to 1100 Watts Max power (550W Max @4-Ohms) and includes a crucial remote subwoofer control. The included wiring kit is comprehensive, featuring speaker wire, RCA interconnects, and necessary terminals.

Key features that stand out:
– 1100 Watts Max Power Class A/B Monoblock amplifier.
– Comprehensive 8 Gauge Wiring Kit with all necessary terminals and loom tubing.
– Mosfet Power Supply for reliable current switching.

• Pros:
  • Perfect for pairing with an existing custom enclosure.
  • Class A/B topology provides warm, clear audio characteristics.
  • Excellent included remote subwoofer control for easy volume adjustments.
• Cons:
  • Requires the user to purchase or already own a separate subwoofer enclosure.

Best for: Existing car audio users who need to power an unpowered subwoofer enclosure, or custom builders who select their sub separately.

Expert Opinion: This kit is designed for the component buyer. The Class A/B design generally offers cleaner sound reproduction than many budget Class D amps, making it a solid choice for sound quality above all else.

Comparison Insights: Finding the Right Sub and Amp Kit

Choosing the best sub and amp kit often comes down to balancing three factors: space, power, and wiring quality.

If maximum, earth-shattering volume is your goal, the Skar Audio Dual 12″ 2,400 Watt SDR package is the clear winner, boasting 1,200 Watts RMS and premium OFC wiring. Skar dominates the high-power vented enclosure segment.

For those requiring a stealth installation or driving a truck, the BOSS Audio BASS8K is the standout choice. Its design integrates the amplifier and sub into a single low-profile powered solution that fits under most seats.

When looking purely at value and budget for a dual setup, the MTX 12-Inch Dual Subwoofer kit provides an affordable entry, though you should check the gauge of the included wiring if you plan to run the system hard.

The distinction between the MTX TNP212D2 and the MTX 12-Inch Dual kit is often overlooked: the TNP212D2 is superior primarily because it includes a stronger 4-gauge wiring kit, which is vital for safety and performance in 400W RMS systems.

Finally, remember that the type of subwoofer used matters. The Skar SDR 10-inch package is better suited than the 12-inch version for listening to music that requires fast, precise bass notes.

Final Verdict: Our Picks

Instead of a single winner, the best sub and amp kit depends entirely on your vehicle and listening goals:

The Raw Power Champion

The Stealth Solution

BOSS Audio Systems BASS8K 8 Inch Powered Subwoofer Kit: The perfect upgrade for modern vehicles or trucks where space is non-existent. It provides clean, controlled bass fill without requiring any separate amplifier mounting.

Best Mid-Range Value Kit

MTX TNP212D2 Dual 12″ Subwoofer Package with 4 Gauge Wiring Kit: This bundle hits the sweet spot between performance and completeness. The included 4-gauge wiring and reliable MTX subs ensure dependable power handling for years of enjoyment.

Frequently Asked Questions About Sub and Amp Kit

What is the primary benefit of buying a sub and amp kit versus separate components?

The main advantage is convenience and guaranteed component matching. When you purchase a sub and amp kit, the manufacturer has already ensured that the subwoofer’s impedance and power handling (RMS) are perfectly matched to the amplifier’s output capabilities. This eliminates the risk of underpowering or blowing your sub and simplifies the wiring process significantly.

Does the gauge of the wiring kit really matter for performance?

Yes, wiring gauge is extremely important. The lower the gauge number (e.g., 4-gauge vs. 8-gauge), the thicker the wire. Thicker wires can safely carry more current with less resistance, which is vital for high-power amplifiers. Using an 8-gauge wiring kit for an amplifier rated over 800 watts peak (or 400 watts RMS) can lead to power loss, amplifier overheating, and potential safety risks. Always use the recommended power cable size, especially for systems rated 1,000 Watts or higher.

What is the difference between a “loaded” and an “unloaded” enclosure?

A loaded enclosure means the subwoofer driver is already installed and wired inside the box. All the kits reviewed here are loaded enclosures (except the final BOSS amplifier kit), making installation quick and plug-and-play. An unloaded enclosure is just the box itself, requiring you to purchase and mount a separate subwoofer.

Can I install a sub and amp kit with a factory stereo system?

Absolutely. Many modern amplifiers and powered subwoofers (like the BOSS BASS8K) come equipped with high-level inputs (or speaker-level inputs). These inputs allow you to tap directly into the existing speaker wires coming from your factory head unit, converting the signal into something the amplifier can use.

How much RMS power do I need for good bass?

RMS (Root Mean Square) power is the critical measurement—it represents the continuous, sustainable power the system can handle, unlike peak power, which is momentary. For basic bass fill that complements your existing speakers, 200–400 Watts RMS is generally sufficient. For loud, vibrating bass (like the Skar Audio kits), you will want 600–1,200 Watts RMS or more.

What maintenance is required for an enclosed sub and amp kit?

Maintenance is minimal. Ensure the amplifier remains cool and dust-free; never cover the heatsinks. Periodically check the screw-down connectors on the amplifier and the enclosure to ensure all wiring remains securely attached, as vibration can sometimes loosen terminals over time.
