What about the sd2 10 do they sound good ported?

I was wondering if it would be better to put behind the back seat of my 06 chvey crew cab 2500hd 2 SD2 8s ported or 2 SD2 10s sealed? The measurements behind the seat are of the enclosure I have now is sealed with the length 47 3/4", height 14", top depth 5", and bottom depth of 7 3/4". I could take out the vents behind my seat and get my box length to around 56" if I get a custom box made. This is my box I have behind the seat now http://www.ebay.com/itm/CHEVY-SILVERADO-CREWCAB-HD-2001-07-10-GREY-SUBWOOFER-SUB-ENCLOSURE-BOX-/281068185596?pt=US_Speaker_Sub_Enclosures&hash=item4170f827fc&vxp=mtr Or would it be better to put them downfire in an enclosure like this sealed or ported? http://subthump.com/product_info.php?cPath=1_72&products_id=57

Would doing the sd2s 8s in a ported enclosure sound better than the sd2s 10 in a sealed enclosure for my truck?

The sealed box I have now is length 47 3/4 ", bottom depth 7 3/4", top depth 5", and height 14". That I could get a custom box build and take some vents out behind my seat to get a length on a box around 56". This is my box I have now in my truck. http://www.ebay.com/itm/281068185596?redirect=mobile

For the sd2s the biggest I could go with would be the 10s for the space I have available. Would they hit really hard in a sealed enclosure?

I am running two kicker cvr 10s in a sealed box behind the my back seat of a 06 chevy 2500hd crew cab. I am running the subwoofers off a rockford fosgate T1000BDCP amp at 1 ohm on these subwoofers. I want to change to some sundown audio subwoofers for this truck which ones would be the best cause I do have limited space? Would 8s be better than 10s in this truck? I want the system to hit as hard as possible thanks for the help.
