    With 4 subs you are better off with one chamber for all. If you go with seperate chambers, you will need a vent for each chamber.

    With a 4.4cuft box tuned to 41, you need a vent 8 inches tall by 2 inches wide. The vent needs to be 4.5 inches long.

    yeah, go to a search engine and type "winisd". Get winisd standard edition. You need to realize though that a computer program is not going to account for the environment of your car, and so your results may vary.

    well, 4 8in Earthquakes totally beats the shit outta my 15rf. I only have about 120watts to each of them and the results are amazing. I had no idea that 4 8s could do that, but they did it. Sound quality isnt actually all that bad compared to my RF, they are by no means good sq, but much much better than that 15RF.
    now i just need a D2 and everything will be good.....
    And thanks again 042801!!!
