I need a sub that is either 10" or 8" that will work in 0.67 cu. ft. and has a maximum mounting depth of 4.5" Will be powered by a JL e1200 monoblock. The JL 10W1-4 is perfect, but the only local carrier of JL is out of stock, and says they are backordered. Does anyone have any recommended replacements that meet my criteria? Or know of an online shop where I can purchase a 10W1-4? I can't seem to find them.
