nascarguy301 Posted March 27, 2013 Report Posted March 27, 2013 Im buying two SQ HDC3 12's D4. Im trying to figure out what box i should build for it. It will be run off a Hifonics BRX 2000.1D. My dimensions are W-32 H-13.5 D-28. Going in an 02' Monte Carlo. I want the box to "come to life" below 34Hz and play down to 26 hz with ease. I like a good range, but wil give up most of the high end for my lows. Thanks Bose = Buy other sound equipment. i love the rattle it's the best part! i need louder cheap amp any ideas?
TRTC360 Posted March 27, 2013 Report Posted March 27, 2013 My friend has his pair of HDC3 12's in 5.5 cubes before displacement, 16sqin of port tuned to 30hz, the lower a song gets the more aggressive it is inside his car, doesn't pick up much above 44hz though, but I bet that has to do with the fact that he's got so much port. If you really care about the lows then i'd say tune around 30-32 with 12-14sqin of port so you can keep some bandwidth in it.
