18 inch audiobahn aw1805x 1200 rms subwoofer.

I have a monster 18 in sub im looking to sell or trade for other car audio or possible 215 trade,this sub is crazy....to much for me honestly.i love bass but this sub can make your stomach turn with a good box.you can check em out on youtube,or google em...i do not have a box for it anymore its been sold.im not in a hurry to sell it and i will not trade down,.anyway long story short im selling my collected car audio for new toys and looking to get at least 250 cash for the sub,not a penny less! Im looking to downsize not downgrade.ill trade for 215 or other subs a realy nice 10 or 12 and cash preferably or a single 15 high rms quality brand sub,cash is best,first come first serve,tired of bs and horrible trade offers everyone just wants to get over on you these days....please be serious and ready to buy the same day as contacting me,no sence in it otherwise.thanks have a good day....
