Kicker L7 Enclosure

I want it loud but with good sq too.  I looking for a good medium between the two.

The best thing that you can do for SQ is to build a sealed box. If you are a Bass-Head you'd be looking at a Tri-Tuned Box (that's what I have and DAMN does it hit hard).

        A ported box is looking like the best thing for ya right now though. Build the box to the specs that Rockford gives out.......it'll help u build it to what rockford says'll be good.

they give three sizes of rcommended volumes for a vented enclosures.  the 3.25 bis the largest.  how would the volume effect the sq.

Depends on how you have it crossed over.....if you use crossovers properly and eliminate clipping, u can go max volume and it will be clean (but loud) music.

What u have to remember that the purpose of a port is that at a certain freq. the port itself will resonate and start producing bass and then take over the sub (i believe that's how it goes i'd have to check my manuals again but i think that's right)... but the bigger the enclosure, the more excursion that you're going to get out of the woofer. This will also change your freq. at which your port resonates at. It depends on what type of music you listen to. If its always bass type music, you're proably going to want your port to begin resonating at about 40-50hz.....or try to tune your box to that anyway. If it's punk rock type music then about 50-65hz that sorta thing.....Ported boxes are always sloppier than sealed, but if done right then it can make good SQ.

So the ques. about volume, it all depends on what you tune your box to.
