About the Q-Logic QLH-CS12
Q-Logic enclosures are famous for their musical performance and their unbeatable construction. Thanks to reliable locking-joint construction and an exceptionally strong adhesive, these boxes are virtually indestructible.
Made of rugged 3/4" fiberboard (which resists flexing and has anti-resonant properties), these boxes are covered with durable gray carpet. The spring clips will accept bare speaker wire and pin connectors. Polyester fiber stuffing and screws are included. (Mounting hardware and grille not included.)
Perfect for most vehicles, except pickup trucks. This box will fit in trunks, hatchback spaces, and the rear area of most SUVs and vans.

Product Research
Materials: The box is constructed of 3/4" fiberboard which resists flexing and has anti-resonant qualities.
Design: For strength, Q-Logic uses a full dado groove on the front, back, top, and bottom panels. The side panels are glued, then locked into these grooves. The edges of the front, back, top and bottom are joined at an angle, so there's more surface area for the special glue that bonds them. The side panels of the box are recessed 0.5". The enclosure is covered with durable gray carpet.
Spring Clips: The
spring clips, located on the right side of the enclosure, will accept bare wire
and pin connectors.
Brackets: Brackets (not included) are recommended for more
secure mounting.
