I have two JBL GTi MKII's for sale. One is brand new in the box and the other is used for about two weeks. I am looking to get $650.00 for them not including shipping. I have the sales receipt so you should be able to get the 3 year warranty JBL offers. Would also consider trade for other Audio equipment worth something. The subs will beat you up, I just don't have enough space in my trunk for the ported box they recommend.
