I don't know if there are any good ones up in Richmond,but none of the ones down here at Fort Lee know which end is up. I'm trying to get one built for a SA 10 that I'm about to order.
this will be a top mounted sub 14in height 35 length 36 width I might be able to squeeze more i'm crippled atm but if its under 4 with those dimensions it will be ok. I am running it at 1800-2k not sure yet want it tuned to 33hz with a nice large port. I'm looking to have it be loud and low, not planning on competing.
