kristoffer Posted October 27, 2010 Report Posted October 27, 2010 Hi a friend of mine is building a box for a 18" AA SMD and he was wondering if 10cubic feet is to mutch for a 18" SMD. The port is 15x4x8 Inches. Quote

OldsBoomer Posted October 27, 2010 Report Posted October 27, 2010 For one woofer yes way to big unless your only giving it a thousand watts agreed... what power does he have? and alos why such a small port? Quote Suburban Coming Soon
kristoffer Posted October 27, 2010 Author Report Posted October 27, 2010 Atm he does net have anything other then a car and the sub :rofl: He told me he was getting a 3000w amp. i don't understand why he bought a AA SMD when he dont even know what ohm is and don't have any friends that know how to design boxes(me included) Would you say 7cf is to big for the SMD powered with 3000w?

David Posted October 27, 2010 Report Posted October 27, 2010 Look on the aa site I think they have some info on box sizes, but from everything I hsve read and seen they like small boxes, look up hugh g reactions build log for what he did with a single 18 Quote

kristoffer Posted October 27, 2010 Author Report Posted October 27, 2010 a car and a sub huh...no wires, batteries, terminals, amp(s), fuses, RCAs, head deck, anything...i would worry about all that before the box he has a stock deck, but i dont think it's got any RCA outputs belive me ive told him 10 times this week to get all that but he went ahead and used the money on a sub he cant power. as for the box im just trying to figure out how big it has to be so i can get him of my back:P Quote
n8ball2013 Posted October 27, 2010 Report Posted October 27, 2010 7 cubes 115 sq inches of port tune to 30 hz. that will do it for now lol.

(im not sure how accurate that would be but it should be ballpark) too much port area in that equation. your figuring 17+" of port per cube. it would be loud, but would unload the sub a bit too easily as well. would be a very short bandwidth on that enclosure.
