Im building a new box and need a little help. The specs that my sub gives for a 2.0 Cubic feet box are- Internal height 19.5, internal width 13.5,internal depth 16". The 19.5 inches tall will not fit in my trunk, the most i can go is like 17" high.Any thoughts on what i should do?

The owners manual says to tune the box to 32 hertz but people keep telling me to tune it to 38 hertz, what do you think?

Well if u tune to 32 hz. U will get deep bass but u will miss alot of "notes". Sealed or Ported? Just remember if u go with a ported enclosure u cant push them as hard. It actually lowers ur subs Max power handling abilities.

I wouldnt put more that 750 watt max to these subs in a ported enclosure. Ive blown 2200w subs in ported enclosures with about 1000w max going to em. That was with 3.5 or 4 inch voice coils

Im going to try and be easy on them, in the owners manual it says that they can handle 500-1250 continuously but they dont recommend anything higher than that.

you wont blow a sub for putting alot of power on it in a ported box unless you have the subsonic filter set lower than what you tune the port at.

power doesn't blow a sub, clipping does. don't heat up the coil and it won't blow.

lower you tune, louder the lower notes are, but higher notes fall off faster. 33Hz is a good place to start. Usually a lower tune contributes to higher power handling.

and if your amp gain is set up correctly, it won't blow. That'* why people put 6000+ rms to a 2500w sub and it doesnt blow, but half of the kids in any high school with systems have blown subs.
