The Kicker SoloX subwoofers were specially designed for “Livin’ Loud” out in the harsh automotive
competition environment. When you push your subwoofers to the extreme, you're bound to find the
breaking point, and when you do you can be secure in knowing that Kicker has provided the SPAIR
(Simple Pull Apart Insertable Replacement) to replace all of the damaged elements of your Solo X
without a lengthy or difficult installation. You can simply remove your old SPAIR, unpack your new
SPAIR, reconnect the wires, drop it into the BAM (Basket and Motor Assembly) and screw it back on to
get your system back up and kicking in a matter of minutes.

Installation
1. To begin installation, start by removing the old SPAIR (Simple Pull Apart Insertable Replacement) from
the BAM (Basket and Motor Assembly) as shown below.
Remove the four (4) Acorn Head Nuts and
washers, and the eight (8) Acorn Head
Bolts securing the old SPAIR to the BAM.
Disconnect the speaker wires from
the old SPAIR and take note of how
they were connected.

A Note on PowerHandlingCapacity SoloX subwoofers will handle massive amounts of power in any of the
recommended enclosures, minimum or maximum. The smaller enclosures are best for use in limited-space
applications. The larger recommended enclosures will yield more bass at the resonate frequency of the enclosure.
The listed Power Handling capacities assume that both voice coils are in use with the appropriate sub-sonic/resonate
frequency filter. Always connect both coils in a dual voice-coil speaker.
Note: The use of a subsonic filter will significantly increase the power handling. The power handling specifications in these charts are
calculated using a 25Hz (56Hz for the Vented SPL enclosure), 24dB per octave sub-sonic (resonate frequency) filter.
