What mods did you have to do to install the 8" sub?In my center console I installed an 8" Ground Zero mid woofer, and I also have a removable box in the cargo area that holds two 10" woofers.
The Kicker 6.75" is a great sub, good price, fits and pounds for it size. I would recommend that one all day long to an owner of a TJ that wants a simple and good sub upgrade. That with your four Skars will be a solid set-up.
If you are thinking of another direction ask away.
