Ok, well ive tryed with two HDC3's but im not getting very good #'s due to the fact that i have only one 20.1 powering them at 1 ohm. This will be a lot of trial and error, but ill see what i can come up with. I was wondering what you guys thought of a single 10" HDC3 with the 20.1 at .5ohm. I realize its too much power for daily, but for burps i would expect this lil monster to hold up for a while. Thanks for any suggestions or help.
O btw, i have a Lumina(not sure on the res frequency of the car). I was gonna try a bunch of different things. Whether its trunk sealed off, or sub up port back or sub forward port back and so on.
Ive narrowed one idea down to a 1.25 ft^3 box with an external 6" aero.
Another is ~3.2 cubes @ 45hz(both subs)
Another was kinda a crazy idea but i wonder if i build a big box in my trunk but with an opening facing into the car. Then put the small box in there. That way my trunk is sealed off completely. It would also force all the sound forward.
Once again these are just thoughts but im really excited for the new season and would like to compete somewhere in the middle of the pack at the least.
