Just get some wire and 4 alligator clips, two clips, clip on the cabinet sub speaker lugs, and 2 clips behind the back of the Polk sub. The aligators clips, clip in there fine on the Polk and work great, easy hook up and ready to play. Yes get the clear mini post rubber/silicon. I got clear ones myself, and almost a year on, and they look new still. Aurich's translite, will sending it over the top. I wouldn't want a pro without his translite in. Nice purchase by the way!! Oh, and checkout Titanpinball.com for the clear translucent silicon rubbers. The ones I got from pinball life last under 50 plays before they started cracking on the slingshots. Titans are a more better quality
