A sub only sounds as good as the box around it, and these subwoofer enclosures take the guesswork out of building one. Audio Apex boxes are offered for single 10, single 12, dual 10 and dual 12 inch setups, each in a standard version and a triple baffle version for heavier, high-power drivers. Pick the configuration that matches your subs and your cargo space, then mount and wire.
Start with driver count and size. A single 10 or 12 inch box suits a trunk you still need for groceries, while a dual box doubles cone area for more output and takes up more room. Measure the opening and depth of your trunk or hatch before ordering, and check that your sub's mounting depth and cutout diameter work with the box you choose.
Every subwoofer has a recommended enclosure volume in its manual. Sealed boxes generally need less airspace and give tight, accurate bass that rolls off smoothly. Ported boxes use a vent tuned to a target frequency, adding output around that tuning at the cost of a larger cabinet. Putting a sub in a box far from its recommended volume can hurt output and let the cone over-travel, so compare the numbers before you buy.
The baffle is the panel the subwoofer mounts to. A triple baffle stacks three layers for a thicker, stiffer mounting surface, which helps with heavy motors and high-power drivers that could flex a single layer. The standard Audio Apex boxes suit daily builds running moderate power. If your subs have heavy motors or run a lot of amplifier power, the triple baffle version is the safer pick; for a moderate daily system, the standard box keeps weight down and still gives the driver a solid mount.
These subwoofer enclosures line up with our 10 inch subwoofers and 12 inch subwoofers, so you can choose the drivers and the box together. Wire dual subs so the final impedance suits your amp, then feed them from a monoblock in our amplifiers collection with a properly fused amp wiring kit. Confirm the sub's gasket seals evenly against the baffle and run quality speaker wire to the terminal so air leaks and loose connections don't cost you output. For more sizes and brands, return to the full subwoofers category.
