I've got a subthump single 12 inch ttop storage box that I am using in my ***** am. Got it made, cost about 300 dollars after shipping. It is custom built to the specs of my RESX12. Id like to sell both of them. The pair sound very good in the back of my T/A. I am just thinking of going a different route, maybe something lighter. It is tan vinyl, has a few knicks in it from stuff sliding around, but I am sure for about 20 bucks you can get it recovered, I can even ask the local interior guy how much hed do it for and I can get whatever color and material you would like. Just message me or leave something in here if youre interested. Any reasonable offer will be considered. I will take a trade plus some cash if you have a 10 inch sub that doesnt require much air, like .6 cubic feet that can handle about 1000 watts rms. Just let me know!
