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.

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.

The amp includes preamp- and speaker-level inputs, so you can install it in almost any vehicle, even one with a factory radio.
