I am no longer looking to set up an IB and have 4 IB318's (4 ohm) that were purchased new last September for sale. I have only run these free air for about 10 minutes to verify that they worked and they have never been mounted. I have the original boxes for these as well. I would like to sell all 4 together but am willing to split them into 2 pairs of 2. I am asking $400 for a pair or $750 if you buy all 4, cash only. Local pickup only. I am in Beaumont, Ca. 92223. I can also meet up near Ontario/Rancho Cucamonga if that works better for you. I have never sold anything on here before but I have been on ebay for several years under the username DMADESIGN. If interested or you have any questions you can reply in this thread.
