I have 2 12in rockford fosgate xlc subs i bought about 8 months ago and put into storage till i was ready to use them. I have only used them for around 2 months. I got a really good deal on a set of ppi 12's so i have no use for these anymore... I bought them at Brandsmart for over $300 for them. I would like to get $175 (you pay shiping) for them. they are 8 ohm so you could run them parrell into a 2 channel amp and get the right ohm load... Prembird If it aint loud then turn it up!
