Built for the Kicker Solo-X
Every Solo-X cabinet is cut with a square opening sized to the Solo-X frame. A round-cutout box will not take it.
Wiring a Pair
Kicker builds the Solo-X in more than one coil configuration. Check the impedance printed on your driver before wiring a pair, and run two of the same model and coil in a dual cabinet.
Professional Solo-X boxes
Ported, standard; single and dual.
2 year limited warranty on Professional
Construction and chamber layout are stated on each product page.

Read the guideKicker Solo-X Box Questions
Which Kicker Solo-X sizes do you build boxes for?
8, 10, 12, 15 and 18 inch, in single and dual cabinets and one triple. Each listing is cut for one size and names it in the title.
Will a round-cutout box fit a Solo-X?
No. The Solo-X is square, so its baffle opening is square. Every cabinet on this page is cut for the Solo-X frame of the size in its title.
Sealed or ported for the Kicker Solo-X?
Sealed is smaller and holds its output below tuning; ported gives more output around its tuning from a larger cabinet. Every ported listing states its tuning and every listing states its net volume.
Do the dual boxes have separate chambers?
The Performance Optimized duals give each driver its own chamber behind a full-height divider. The Professional Series duals share one chamber and one port, so run two of the same model and coil.
Is the Kicker Solo-X included?
No. These are enclosures built to fit the Kicker Solo-X; the driver is sold separately. A listing that ships with the driver fitted says loaded in its title.
How should I wire the Kicker Solo-X?
Kicker builds the Solo-X in more than one coil configuration. Check the impedance printed on your driver before wiring a pair, and run two of the same model and coil in a dual cabinet.
What warranty do these boxes carry?
It runs by series: 1 year limited on Performance Optimized, 2 years on Professional and Micro. The series is named in each listing title.
