Dayton Audio RSS315HO-44 12" Reference HO DVC Subwoofer
I'm looking to run a single 12" for an SQ set up for car audio. My question is how does the HO Ported compare to the UM Sealed? What is the best size box for the HO ported after sub and port displacement and correct port length? UM needs 3cf sealed?
In order to get a relatively flat response the HO will need about 2.5 cubic feet total tuned to 29 Hz and heavy fill. This will be louder when compared to the Ultimax and have a stronger bottom end, but will roll off sooner and not play as low below about 25 Hz. The Ultimax will work in smaller enclosures with good results in a car application, 2 cubic feet will work well.

I installed this speaker in a 2.4 ft^3 net volume cabinet with a 3"x15.5" vent tuned to 21hz. I modeled the speaker with WinISD software for a nearly flat response from 25 to 100hz. Would the 1.3 ft^3 produce a more extended lower end in the real world?
A smaller volume will produce more output above the tuning frequency. The larger cabinet will have a more extended low end in the real world, depending on application of course.

2.5 cf box w/ 2 4"x10" ports ok or would the rss315hfa-8 be a better choice
That volume and port size will tune the box to about 43 Hz which is pretty high, and will cause a peak in the response. A single 4" port will drop the tuning to 31 Hz but will still have a bit of a peak. The HO model will be better suited for a vented box but knowing where you would like it tuned will help with modeling.

if i put the Sub in a sealed box of 19 liters, What is the minimum power required by the amplifier? is 200W is enough for Average Apartment?
There is no such thing as minimum power without knowing the output levels you are trying to achieve with a given driver. 200 watts will work for low to moderate levels but headroom is always recommended with subwoofers, even if they aren't turned up very often.

In the description it said Bassbox pro suggest sealed .49 cu ft for this sub. Is this right? It seems a little small to me. What is the proper sealed enclosure for this sub? Thanks
That volume is accurate for this woofer.

I have this sub in 1.6 ported enclosure with 3"aero port tuned to26hz.i have 600 watts of alpine power going to it,gain set with dd-1.this sub wants more,my question is how much more power can I feed it(safely)?
Since the sub is only rated for 700 RMS you won't want to give it too much more or you will start to run into thermal issues. The sub will handle the full 700 watts down to about 20 Hz without excursion issues. I usually try to have headroom with my subs, so an amplifier that is 800-1000 watts RMS will work well, you just don't want to crank it full gain for long periods of time.
