That is my question. I runnin' 2 12" subs with about 600w rms. I've fixed my light dimmin' issue so I'm good there. I recently "won" a SCKH1 Stinger cap W/ the install kit, dig. read out, and all the goodies (it's about a $130 kit). I'm just wondering if I should bother putting it in or not. Whats your opinion's on caps???
