JL Audio 12TW1 Microsub
JL Audio RBC1 Bass Knob
KnuKonceptz Kolossus 8 Gauge Amp Wiring Kit
Straightforward setup thanks to this forum.
Tapped into the rear 12v for power, ran the negative to the chassis ground adjacent to the 12v.
Ran the speaker wire to the rear deck sub and connected via alligator clips.
The sub sits perfectly in the false floor in the trunk, no mods required--it's also has a quick-connect, in the event that cargo space is needed.
Routed the bass knob to the lower dash panel to the right of the steering wheel, just for preference.
After having this setup for a while, and having a loaded loaner, there's no way I'd spring for the SSP setup; YMMV.
