opinons replacing my subs in current setu

Hey guys I'm new to the forum. I'm really having a hard time deciding which subs will fit my setup well. I had the mtx jackhammer JH5512 sub enclosure. I got these from circuit city right before they went out of Buisness. I had a 800 watt pioneer amp on them for a while and then finally upgraded my amp to MTX thunder elite 801d amp. This was perfect match for these subs the amps birth sheet showed 485 rms @ 4 ohms and 815 @ 2 ohms. These called for 400 a piece as box was wired at 2 ohms. I wired it up on them jackhammers and they lasted about a week before they blew. Everyone I've talked to said MTX has really stepped there game up and make great amps and are usually underrated. The enclosure is really nice and I'd like keep it as its a large ported box in 2 ohm setup. Most subs I've looked at call for basically this same cubic ft displacement ported which is about 2 cubic. I want to replace the two twelves and get something that's really going to shake things up but sound good too as I love bass and to feel it in my chest. I was looking at 2 12 inch JL w3v3 the new ones or 2 12 inch alpine type rs. I would wire them to 2 ohm setup so each speaker would be receiving about 400+ rms running speakers in parellel. I would like peoples inputs and am also up to suggestions of any other subs as well. These are going in a 07 Dodge Magnum so its no little car. Please any help would be appreciate and I need to do something because no bass just isn't cutting it! Thanks in advance.

Sorry forgot year make and model. That's a 2007 Dodge Magnum SXT

Those jls are nice,but your box is the most important aspect of your bass. That box is tuned to a certain frequency , so you need to find subs with very close to exact cu.ft. measurement, speaker displacement so that you get the best sound possible from that box. You might look at re audio, I have had good luck with them but dont know if there right for your app. re audio.com is there site. also read the "how to set your gains properly" sticky on this site ,I have a feeling that had something to do with how you "blew" your last subs-A vision without a plan is just a hallucination-

Well the place where I bought the amp and I get most my stereo work done set the amp up and the gain was I think only a little over 1/4.
