FAQs

Does this enclosure come with a subwoofer?

No, this is an empty enclosure designed for you to install your own 8-inch subwoofer driver.

Will this fit in my car?

The In Phase 8-inch enclosure is designed for universal compatibility and fits in the majority of vehicle trunks and cargo areas due to its compact footprint.

Why choose a sealed box over a ported one?

A sealed box is generally preferred for sound quality and accuracy, offering a tighter bass response, while ported boxes are usually for maximizing total volume.

What is the thickness of the material used?

The enclosure is constructed from 18mm high-density MDF, which provides excellent structural integrity.

How do I connect my amplifier to the box?

You can connect your speaker wires directly to the high-grade gold-plated binding posts located on the back of the enclosure.

Troubleshooting

The bass sounds weak or hollow.

Check the speaker wire polarity at the binding post and ensure the subwoofer is properly sealed against the MDF face with a gasket.

There is a rattling sound during playback.

Ensure all mounting screws on the subwoofer driver are tightened fully and verify the box is secured to the vehicle floor.

No sound output from the subwoofer.

Inspect the connection at the gold-plated binding posts and verify that your amplifier is outputting a signal.

Setup, Compatibility & Care

To set up this enclosure, you will need an 8-inch subwoofer driver, speaker wire, and a mounting screwdriver. Carefully feed your wire through the internal opening, attach it to the subwoofer terminals, and secure the driver into the MDF face using the provided mounting holes. To maintain the enclosure, keep it away from direct sunlight to prevent carpet fading and ensure it is firmly secured in your vehicle using straps or brackets to prevent it from sliding during turns. Regularly check the binding post nuts to ensure they remain tightened for optimal signal transfer.
