I have a Rockford Fosgate P3D4-12 subwoofer in the CT1X12 box running off of a Rockford Fosgate R2-500X1 (Birth sheet = 622RMS @ 2-ohm) in a 2003 Kia Spectra (Big3 done w/ 4Gauge wire). The setup currently has about 15-20 hours of use and the box fit really nice in the trunk with enough room to still fit groceries and other stuff.
My initial impression of the box is it seemed to be well constructed and was very well packed when delivered. There really weren't any blemishes that I could tell of inside the box or outside. Overall, the sound is really good and better than I expected.
At this time and hour usage, I really can't say anything bad about the box. I consider it money well spent.
It made a huge difference in the base and the feeling of the base. Noticed way deeper and controlled notes. Great box overall
Solid box, nicer than some 200$ options sold online.
Bought the Tropo XL 12 and CT 1000.d with this enclosure. Have it turned about 1/3 of the way up for break in but DAYUM! It sounds fantastic. Highly recommend.
