im looking for a box design for 3 15 inch hdc3's in my 92 jimmy. was thinking about using aero ports but havnt had a chance to really look into them yet. im probably going to run them at about 2500 watts and would like it tuned to around 32-34 hertz. the car wil be a weekend driver. and will hopefully compete with 3 15 inch btl's. any ideas?

The HDC3's will chuckle at that power. I'd suggest looking into the SDC2.5's with that amount of power. Either sub you choose the box for the (3) of them is going to have to be roughly 11.5-12.5 cu/ft net. I'd bump the tuning up around 36 hz also as they were designed to be tuned to 36-40hz. Specifically 38hz. And subs up/port back will work well in your truck. The sdc2.5 are great subs and WILL get loud. If your planning on sticking with your current amp def look into them.

X2 on the 2.5's the HDC's are meant for more than what you have for power...
