If you are still looking for a Z, im on Long Island and pretty easy for me to make trips if its on the weekend. Let me know.

if it wasn't my z i would love to work with you on this but my z is all about speed and losing weight haha, i have done a couple different custom boxes for myself and other people, at least there is more room in the back of the z than i had in my 92 firebird (which i made a box for 2 10s and 2 12s along with xbox and 2 tvs. that was waaaayyyy before they made shallow subs too so you had to have a box that was 1 million sq ft lol
