Skar Audio Dual 12″ SDR Series Subwoofer Bass Package
This All-in-One SDR Series package includes a dual 12-inch loaded vented enclosure and matching amplification. The listed power handling is 2,400 watts peak and 1,200 watts RMS, making it suitable for drivers who want strong low-end output without sourcing separate components.
Key features from the listing: integrated loaded enclosure, dual 12″ drivers, and amplifier matched to the enclosure. The vented design supports deeper extension compared to sealed boxes of similar size. The package simplifies installation for users who prefer a single matched solution.
Skar Audio Dual 12″ EVL Series Vented Subwoofer Enclosure
The EVL Series is presented as a competition-grade option with a 5,000 watt peak and 2,500 watt RMS rating. The enclosure ships with dual 12″ subs mounted and pre-wired to present a 1-ohm load at the terminals, intended for high-power mono amplifiers commonly used in SPL or competition builds.
Notable listing points: heavy-duty components for high SPL, pre-wired internal configuration, and vented (ported) enclosure tuning. This product focuses on maximum output and requires planning for amplifier selection and vehicle electrical capability to realize rated power.
MTX 12-Inch Dual Subwoofer With Amp & Wiring Kit Bundle
This MTX bundle pairs a dual 12-inch loaded enclosure (1,000W RMS listed in marketing copy) with a Planet Audio monoblock amplifier and a complete 8-gauge wiring kit. The Planet Audio amp offers variable bass boost, low-pass filter, and high/low level inputs for flexible tuning.
Listed features emphasize durable 5/8″ MDF enclosure construction, aircraft-grade carpet wrap, and accessible controls on the amplifier. As a bundled solution, it caters to buyers who want a near-complete kit for easier installation and tuning without sourcing individual components.
Rockville RV12.2B Dual 12″ Car Subwoofer Enclosure
Rockville’s RV12.2B ships as a dual 12″ package with a matched mono amplifier and wiring kit. The listing cites 1,200W peak / 400W RMS (CEA-2031) compliance for the subs and notes a quasi transmission line cabinet built from quality MDF for controlled bass response.
Included amp features and CEA compliance are significant, offering clarity about power handling under industry testing standards. The cabinet style aims for balanced low-frequency response rather than purely maximum SPL, supporting musicality in many car environments.
MTX Dual 12-Inch Terminator Loaded Subwoofers
This MTX Terminator dual 12″ loaded enclosure lists a 1,200W peak and 400W RMS capability with design elements like a 2″ aluminum voice coil and 48-ounce motor magnet for sustained excursion control. Polypropylene cones and rubber surrounds are noted for durability.
The product targets buyers seeking a simple, enclosed dual-12 solution with reliable components. The 5/8″ MDF construction and black carpet finish are standard for loaded enclosures aimed at broad compatibility with many vehicle trunks.
Buying Guide: How To Choose The Best Dual Subwoofer For Your Car
Selecting a dual subwoofer package requires balancing power handling, enclosure type, vehicle space, and electrical capability. Use the checkpoints below to compare models and make a practical choice.
1. Power Ratings And Matching Amplifiers
- Peak vs RMS: Peak ratings are marketing spikes; rely on RMS for continuous power guidance.
- Amplifier Match: Ensure the amplifier can deliver the subwoofer RMS at the impedance the enclosure presents (1Ω, 2Ω, 4Ω).
- Vehicle Electricals: High RMS draws may require upgraded alternator, battery, or capacitors to prevent voltage sag.
2. Enclosure Type And Sound Goals
- Vented/Ported: Better low-end extension and efficiency; larger enclosures and more pronounced boom.
- Sealed: Tighter, more accurate bass with less extension; smaller enclosures.
- Transmission Line/Quasi: Designed for controlled, musical bass response at specific tuning points.
3. Subwoofer Size And Vehicle Fitment
- Dual 12″ vs Dual 10″ or 8″: Larger cones move more air for deeper bass but require more trunk space.
- Check Dimensions: Verify enclosure external dimensions against trunk space and spare tire access if needed.
4. Build Quality And Cooling
- MDF Thickness & Bracing: Thicker panels and internal bracing reduce resonance and distortion at high output.
- Voice Coil And Motor Size: Larger magnets and voice coils improve power handling and thermal endurance.
5. Installation Convenience And Included Components
- Bundles: Packages that include amplifiers and wiring kits simplify installation but check component compatibility.
- Pre-wired Enclosures: Pre-wired terminals and factory tuning speeds installation; verify final impedance (1Ω, 2Ω).
6. Listening Preferences And Genres
- SPL/Competition: Look for high RMS handling, vented competition enclosures, and pre-wired 1Ω loads for maximum amplifier power.
- Musical/Everyday Use: Quasi-line and sealed designs, or moderate RMS ratings tuned for balanced response, deliver controlled bass suitable for varied music.
7. Objective Comparison Tips
- Refer To CEA/ISO Specs: When available, CEA-2031 or similar standards provide a neutral basis for comparing power and efficiency.
- Impedance And Wiring: Confirm the final terminal impedance; wiring options change amplifier pairing requirements.
- Space vs Output Tradeoff: Larger enclosures produce more bass but reduce cargo space—evaluate based on vehicle usage.
