Hey guys recently got a alpine type r 10 inch because of a new car and limited space. i just put it in a 1 cubic foot box for now to break it in, its sounds alright. but soon i want to put it in a nice big ported box.

i dont know how to use that winiSD program or anything but maybe someone can help me.

I was thinking like 1.75 cubic feet tunned to 27 hz?

is that too big, i just want to get the most out of this little guy.

Too big and tuned too low.1.25 cubes and 32 Hz if you're looking for good low end.

alpine recomends 1.3 cubes at 33hz. i was just wondering if i could get it louder by puttin it in a bigger box.

i have it hooked up to an aq 1200d at 4 ohms 510 watts, you think this little guy can handle 1200 watts at 1 ohm if i set the gains properly?

The 'Sub-Chebyshev' and 'Quasi-butterworth' alignments in WinISD both call for ~1.65 cu.ft. tuned to ~24.5Hz for the the flattest response.

Ofcourse this low of tuning really isn't necessary in a car, so Id say 1.4-1.6 cu.ft with a 29-32 Hz tuning would be great. But designing a box of that size to be tuned low and not have high port velocity is tough.

1.5 cubes with 4 inch aero it is. i was looking at an AQ Hdc3 10" and they recomend 1.5 cubes for their sub so if i want more power ill sell the alpine and change the aeroport.
