I don't know if you guys could do it, but speaking of, a great thing you could do for the DIYer is sell "mix and match" parts, IE 2-3 basket/motor combos, a few different cones w/VCs and suspension, etc so a DIYer could assemble their own woofers to their own taste. It would save you $$ on labor and it would be alot of fun for the DIY type person. Of course, you couldn't be held responsible for someone being completly incompetent and ruining a coil from horrible alignment, so a warranty would be tough, but I still thing it would be a fun sell to have some "make your own sub" options
