Hi guys, I have a 18 ft subwoofer cable from Monster, it's the Monster Bass 300 one. I used it once for 10 minutes (not kidding)... I originally was going to do a dual subwoofer set up but after re-evaluating. I think my Energy S8.2 is well capable of handling my bass for now. Hence why I also have the Y splitter which is un-used. Y adaptor goes from one male to two females. $33 shipped to the CONUS for the subwoofer cable. $12 shipped to the CONUS for the Y adaptor. or buy both for $40 shipped! Prices are OBO, so PM me or email me for offers, please, lowballs will be ignored. I prefer paypal. I have done a few transaction on this board before, so I do have refs here. Thanks.
