I wouldn't put them in the rear deck unless your good at fabrication. I would just buy two of the S2W8's throw a good 1500 watt amp on them and have Starr Mountain Sound build you a vented enclosure to fit your trunk. They only take a max of .86^cu.ft net to get theses S2's to sound good and get loud. I did a 1.5^cu.ft net enclosure and have two S2W8 single 2 ohm running off a Soundstream Rubicon 2500.1d and they slam pretty good.
