I don't think they are THAT valuable, however if they are in great working order, then $200+ shipping would be a reasonable price to ask.I bet you could get a good amount for them on ebay. Find the right enthusiast and I bet you could get at least 300-350 for the pair. If they're in as good of shape as they look
my friend bought them new and used them for only 6 months or so. he sold his ride back then and they just sat in a closet since. and i got them because i did a full and i mean FULL audio install on his g35. I have no use for them and would rather sell them and use the $ for some icehow long have u used them
