I have 2 1508s on a memphis 1000d in a t line enclosure plays down to 20 hz works best in my 93 hb civic if about 8 inches from the side (labrith ends on passanger side of box drivers on top of box) they want more power pushing it clean power they will take 500 each easy I really think with clean power in my enclosure Pete PWKDESIGNS.com built for me could easly take.... 1000 each or so... can't wait to put a sundown 3000 to them adventualy
I must say for 2 8's in a small car they have tight bass for sure and for how wide of a range it plays gets pretty loud and does so flat. GREAT daily system just wish I had more power
