[QUOTE="Synastr, post: 8202418, member: 657828"] Ok, so I recently purchased two sundown e8v3s dual 2ohm. I'm building a box for four subs under my silverado but until everything is done. I wanted to try them. So one box is a slot ported box .9cft before sub. So it's roughly a .85 box. The port seams to be tuned about 35hz. With this box, the sub hits the punch good but low notes just sound like air. The subs distorts really easily before it has much power. My amp is a ampere audio 1000.1 clamped at 1200watts at 1ohm. The amp is not to blame. I've got it set to push 400watts at volume 35, but the sub won't take it at 22, it sounds blah. Box 2: Box 2 is .83cft before sub and port. It's a 3" port 18" long. The sub had to be inverted to clear the port. This box hits lower but you still can't give the sub maybe 200watts tops. This box while turning up sounds better than box 1. But then starts to distort. So can any body enlighten me on these subs? Do they need "broke in"? Is it just my boxes? The box for 4 is going to be 2.73 after subs but not port. I plan on a 4" port tuned to about 29-31 [/QUOTE]
