Is it the box or the sub?? Volume won't go higher... Is the port just too long?

I could believe this but I still wonder if the voltage drop had anything to do with it ?

If you have a 1000watt amp and your dropping to 10.8v you have bad connections or bad battery or something just ain't right.

I had this issue with my van and I added a second battery and beefed up alternator cables and problem was gone. This is problem here is with my daily and I really don't like to pour money into it so try to do everything on the economical side. I found this battery , what do you think ?? I realize it's not the best but will it suffice ?

Eh, I see , it's optimal for 600 watts, guess I need a 1000 watt min. This ***** - but I'm not happy with seen the drop.

Should voltage be stable ? What's the range on a good voltage ?

12.6v-14.8v

12.6v-14.8v

So it's ok to move from this max and min?

You want to try to stay above 13.3v at all times, but 12.6-14.8 is considered "safe". Most guys try to stay within 13.3-14.4
