Alpine S-DB8V-TRK Halo Series 8″ ported dual subwoofer enclosure with two 8″ S-Series subwoofers+ Alpine S-A60M S-Series mono subwoofer amplifier 600 watts RMS x 1 at 2 ohms Alpine

Overview: The Alpine S-DB8V-TRK enclosure features two 8″ Alpine Halo S-Series subwoofers pre-loaded in ported enclosure that’s designed to mount underneath most full-size truck rear seats (Crew Cab) in a down-firing configuration. The dual subwoofer enclosure can handle 300W-600W RMS and features a tuning frequency of 36Hz.

Enclosure: The Alpine S-DB8V-TRK is made up of two separate ported subwoofer enclosures that are linked together using the included front and rear ProLink brackets. Each enclosure is constructed of 5/8″ MDF and covered in premium black carpet with the port tubes firing out each side. The center linking brackets can be adjusted, providing between 40″ and 51″ of enclosure width, allowing it to fit under the rear seats of most full-size Crew Cab trucks. Two amplifier tray brackets can be mounted between the two enclosures, allowing a wide variety of amplifiers to be mounted to the enclosure. Each tray bracket must be drilled to match the amplifier’s mounting holes. With the enclosure in its widest mounting configuration (51″), the amplifier tray brackets provide 11″(w) x 9″(d) of mounting space for an amp. Both of the enclosures include three installed stacking feet that provide an inch of clearance for the down-firing subwoofers. Additional stacking-feet spacers and rubber feet are included for mounting the enclosure on an uneven floor.

Note: The amplifier mounting trays may not be applicable for all vehicles, depending on the amount of under-seat space (width) available.

Drivers: The S-DB8V-TRK includes two pre-loaded S-W8D2 8″ S-Series dual voice coil subwoofers. Each driver features a paper and Kevlar reinforced parabolic cone with a mica/talc dust cap. Alpine’s High Amplitude Multi-Roll (HAMR) surround combined with a high-excursion voice coil provide deep powerful bass while maintaining airflow. Dual 2Ω voice coils are internally wired for a 4Ω load at each enclosure’s terminals. This lets you parallel-wire both enclosures for a 2Ω load at your amplifier’s output.

Terminals: The two subwoofer enclosures feature a pair of spring posts that can accommodate speaker wire up to 12 AWG.

Compatibility: The Alpine S-DB8V-TRK subwoofer enclosure is designed to mount underneath the rear seats of most full-size Crew Cab trucks. Confirmed vehicle fitment includes:

2018-up Chevy Silverado Crew Cab
2015-up Ford F-150 Crew Cab

Alpine makes it a little easier to get great bass in your vehicle, especially if you drive a compact car. Their S-Series S-A60M mono subwoofer amplifier can deliver up to 600 watts RMS to your sub, guaranteeing some powerful bass on your drive. And Alpine made this amp so small — it’s got less than an 8″ by 8″ footprint and it’s just over 2″ tall — it can fit almost anywhere.
Technology that keeps you on the air

Enhanced Shutdown Performance technology rolls back the output a bit when the amp threatens to overheat from playing at its limits too long. Instead of shutting down completely, it continues playing your music, until it cools enough to return to full power.
Convenient features

A low-pass filter and adjustable bass boost put you in command of the frequencies that reach your subs. The amp includes preamp- and speaker-level inputs, so you can install it in almost any vehicle, even one with a factory radio. If you’re using the speaker-level inputs, the amp senses an incoming signal and turns itself on, eliminating the need to run a turn-on wire back to your vehicle’s receiver or fuse box. An optional wired remote lets you control bass level from the driver’s seat.
