I have two Kicker Comp 12 inch subwoofers, about 200 watts RMS and a Kicker ZX400.1 amplifier rated at 483watts RMS. They are about 8 months old. I gave over 600 dollars when I got them. Both subs and amp are in very good condition, no more than 150 hours on them. I am asking 400, but I am willing to negotiate for a lower price or maybe a trade. Please let me know if you are interested.
