I have two SSCTF kicker boxes for sale here in Macomb Township Michigan the first one is the Kicker SSCTF by Stillwater design. This unit has two 10inch Kicker subwoofers, Two 2 inch tweeters, and two horns, with the 4 ports on the rear. The box is a little dirty but would clean up. The second box is considered the CTF kicker box by Stillwater design. This unit has two 8 inch Rockford Fosgate sub woofers, and two horns, and had the rear radiators which were basically a speaker material but didn't have any driver. They were filled in with boards to fill the hole because the radiators fell apart after some years. I had these boxes in my cars over the years and they sounded pretty good, there are some that swear by them and other that swear at them...I Liked them, I started with the 8 inch, but when they came out with the SSCTF with the 10's I had to have it. I have been sitting on them waiting to get another Camaro or Firebird but still haven’t got one, so I have to let them go. $200 for the 10 box and $150 for the 8 box. plus shipping or local pick up.
