Ok, so currently i have an aftermarket alpine deck, and a kenwood KAC-(somthing) which pushes 500Wx2ohm, and 300wx4 ohm. (rms of course.) Now i used have an ancient BLAUPUNKT sub with a ported box. I threw the sub out but kept the box. The box's volume is approx 1.29ft cubed (w/o port volume) and it has dual cardboard ports 9 inches long 3 inches in diameter. Can i put an alpine type r 10 inch in the box and just cut a port out and thus tune it to ~ 34 hz? or am i missing a step somewhere?
Using a pos box like that will make your sub sounds like crap, garenteed.... on the other hand getting a good box or making one can make it sounds good. The box has more effect than the speaker in it, remember that.
