Component Subwoofers at Crutchfield.com
Looks similar to the latest run of the mill infinity.... Not that expensive new. I believe those are 12" subs....
That box would make really good kindling... Who leaves fastener exposed? Mine was sealed with glue..... sealed with bondo on the outside to make it PERFECTLY SMOOTH and then siliconed on the inside. I then went and had it Line-xd..... No air got out.
It didn't cost that much more to do it right and it was soooo nice.
I think at best I could have gotten $200 out of that setup but it wasn't the top of the line Sony stuff..... I got tired of looking at it in the Porsche and had moved it to my Corrado..... I just left it in the Corrado when I sold it...
