- Does this box come with a subwoofer?
- No. It is an empty enclosure, so you choose and install your own sub. Check the cutout and mounting depth before buying a driver.
- Which trucks does it fit?
- It is shaped for extended-cab GMC and Chevrolet Silverado trucks. Crew cab and regular cab models use different boxes, so confirm your cab style first.
- What subwoofer size does it take?
- It is built around a common single subwoofer size, but confirm the cutout diameter and mounting depth against your driver's specs. A sub that is too deep will not seat properly.
- Is it 4 ohm?
- The 4-ohm figure refers to the wiring terminal, not a built-in speaker. Final impedance depends on the subwoofer you install and how you wire it.
- Does it fit under or behind the rear seat?
- It is designed for the rear area of the extended cab. Seat brackets and trim vary by year, so test-fit before final mounting.
- Is it worth it over a generic box?
- If you want a hidden install with no fabrication, the vehicle-specific shape is the reason to choose it. A universal box can work but usually needs trimming and takes up more space.
