first post woot :)
im looking for help with building a ported(vented) box for 2 DB1240's powered by a hifonics HIFI 1000D amp. I've done a bit of reserch and stuff and something that keeps confusing me is the different tuning for ported boxes. i know you find it by getting the area of the port and stuff, but what does it do, like a box tuned to 33Hx vs a box tuned to 40Hz? Also what would be a good tuning for listening to a lot of metal with fast low double bass and big bass drops :D. and i know sealed is the best for this but i want it louder and i am currently maxing out my alternator with what i have right now, so i cant just go with more power:(. And what's a good amount of airspace for each of these.
right now Ive' got 6.5 DB components in front and coax in the back of a jeep Cherokee (XJ), and i had a 12' hifonics brutus sub (in a sealed box) and hifonics HIFI1000 amp, but it got stolen.
