Designed for serious bass, this 8" quad-ported sub box delivers deep, resonant low-end with a 38 Hz tuning frequency and 2.50 ft³ total air volume. Its 7 1/8" cutout diameter (custom sizes available) and 1-slot port with a 30 in² area ensure tight, controlled bass that fills your Silverado cabin. Weighing 57 lbs with a 7 1/4" mounting depth and a 1 1/4" front baffle, it’s built for a secure, high-performance under-seat installation.
With a front height of 9 3/4 inches and a rear height of 6 1/2 inches, this sub box slides neatly under your Silverado’s rear seat for a clean, low-profile installation. Its 53" length maximizes internal volume for deeper, fuller bass performance. A 17" depth provides stability and durability, ensuring a secure, long-lasting setup for powerful, forward-firing sound.
Crafted from 5/8" high-quality MDF wood, this sub box is built for strength and long-lasting performance, even under intense bass loads. It’s carpeted with a durable trunk liner finish and sealed with high-quality Titebond silicone and wood glue for a vibration-free, airtight enclosure. Four spring-loaded terminals provide secure, easy connections for a professional-grade, high-output audio setup.
Dreaming of the next generational subwoofer to install in your car audio system, the Alpine R2-W8D4, which belongs to Alpine's newly updated R-Series subwoofers that are known for exceptional bass accuracy, power output, and reliability, is an excellent option you should look into. The Alpine R2-W8D4 comes with a Kevlar-treated cone, giving this 8-inch subwoofer the durability necessary to produce high-quality bass at loud volumes for extended periods. It also has Alpine's High Amplitude Multi-Roll surround, which allows the cone to perform at a maximum level while having excellent thermal efficiency.
Its new motor structure comes with massive double-stacked magnets allowing the subwoofer to produce an extensive low-frequency response and more solid bass control. All R-Series subwoofers, including the R2-W8D4, come with dual voice coils with many configurations to choose from, making them flexible in many subwoofer applications. The Alpine R2-W8D4 is a subwoofer with a power output of 350 Watts RMS and 1000 Watts peak power at 4 ohms. Its sensitivity rate of 83.7 dB and frequency response of 30 up to 200 Hz tells it all that this 8-inch subwoofer won't have any problems performing heart-pounding bass tracks at loud volume levels.
