This is a direct replacement for the Kicker Hideaway 11HS8 subwoofer. The OEM drivers have a design flaw that causes the tinsel leads to fatigue and break at the glue joint. These replacements are designed to the OEM specs but solve the design flaw by allowing the leads to float and not be woven into the spider. This version is a dual voice coil. The coils must be wired in parallel for maximum output. (+ to +) and (- to -) using 16ga wire.
