Traded in the X now got the sub for sale. I used a 1 channel 2 ohm 400W rockford fosgate amp on this and it was able to shake the rearview mirror. This is made of fierglass and its pretty heavy.

This kicker 8" sub is a great addition to a stock system w/o dsp.

Looking to get $150 plus shipping or best offer.
