Alpine R2-DB8V-TRK Halo Series 8" ported dual subwoofer enclosure with two 8" R2-Series subwoofers+ Alpine R-A75M R-Series mono subwoofer amplifier 750 watts RMS x 1 at 2 ohms

Your truck deserves more than any old subwoofer system — you want sound and style. Alpine's R2-DB8V-TRK loaded subwoofer enclosure gives you both. This versatile enclosure features two of Alpine's new R2 subs and will fit most full-size trucks.
Solid subs

The R2-DB8V-TRK features two Alpine R2-Series subwoofers with Kevlar-reinforced pulp cones and rubber High Amplitude Multi-Roll (HAMR) surrounds for dependable performance at high volume levels. The enclosure handles up to 750 watts RMS so you'll get the solid bass you're looking for and is wired for a 2-ohm load, making amplifier selection simple. The enclosure's side-firing ports use your truck's interior to boost the lows, giving you deeper bass at higher volume levels.
Easy to fit

The rugged 5/8" MDF enclosure is clothed in black carpet covering that combines toughness and good looks, with a central metal Pro-Link™ bracket that lets you adjust the enclosure's total width from 40" to 51" to fit under the seat of most full-sized trucks or in the cargo area of the Jeep Wrangler or Gladiator JK and JL. An integrated amplifier mounting tray is optimized for Alpine's mono sub amps, and its EZ Change twist-lock grille system gives you speaker protection options to coordinate with your truck's interior. Adjustable mounting feet ensure a secure fit.

For loud and realistic-sounding bass
Alpine Authorized Online Dealer

Alpine's R-Series R-A75M amplifier cleanly reproduces the bass in your music so you can enjoy the enhanced realism you want in your vehicle, even when you're playing high-res music. They've applied some hot technology from their top-of-the-line X-Series amplifiers into this R-Series amp. This includes the use of high-efficiency transformers and premium custom capacitors in the amp's construction. Dual "Sierra" feedback circuitry decreases distortion by correcting the output using the original input signal.
How much power?

The R-A75M mono subwoofer amplifier puts out up to 750 watts RMS, conveniently and perfectly matching the power ratings of Alpine's R-Series subwoofers. Advance Class D amp technology allows this amp to be built so small it'll fit in almost any of the tiny spaces available in many cars and trucks these days. You can adjust the amp's low-pass filter, bass boost, and subsonic filter to get just the right bass tone. Plus, you can add the optional RUX-KNOB.2 remote bass knob to control your bass from the dash.
