How low can two 10" Dcons go?? I wanna make a ported box tune to 30hz but I listen to a lot of hip hop, dnb and dubstep. So, I want them to hit low, to vibrate my car pretty good(94 Corolla sedan). The power is 500w rms.

The Dcons will work well.

you can make any sub "hit" lows. it is almost completely enclosure dependent. After seeing what SSA subs can do, I bet they will get lower than you think, and be loud doing it.

Sounds good to me!! I must gather a few bucks to buy mdf, jigsaw, glue, screws and more and start messing with wood. I never made a sub box in my life, never work on wood, but its a matter of time because I want to learn. So thats my plan for 2012, make a box for those sweet looking Dcons ...thanks guys!!
