sub wiring, parallel or series?

i have 2 memphis 12s 250watts each.powered by memphis 500 watt monoblock bridged to 2ohms. the subs are svc and i want to know is to better to wire them in series or parralel , the diagrams are under4ohm svc in the sub wiring section thanx. -A vision without a plan is just a hallucination-

thank you sorry about the misinterpretation of bridged .do you know if putting pillow stuffing in your sub box tricks the speaker into "thinking" its in a larger area, theory:pillow stuffing slows down the air movement thus creating the deception of a bigger area. my subs are going into a box that issealed and divided and is 2.cuft total. i would like the bass to carry more it hits good now and is very quick and clean. is there a way to get it to carry more such as drilling a cerain size hole kinkda of like a make shift port?-A vision without a plan is just a hallucination-

sic audio: the dimensions of my box are 48.5x14.5x 6.5 top/8.5bottom.my sub are 2 memphis 15-pr12d4-A vision without a plan is just a hallucination-

And that is COMPLETELY wrong. The VAS of the drivers does not change, simply because you cut a hole between the chambers. The response of the system will remain as close to identical as you can get, and simply cause you additional work. Also, you can't "just port" a box. You can't. A vented box will be HUGE compared to a sealed enclosure for the same response. If you are happy with the way they sound currently, leave them alone. If you want a different response, you MUST build a different enclosure. Sorry, that's just the way speakers work. To answer your stuffing question, stuffing can only gain you about 10%, but yes, the driver will "think" it is a larger enclosure, with the addition of poly or dacron, but the best option is long-fiber wool, or Acousti-Stuff, available from Parts Express for not much change.

Finally... I didn't think it would take very long...It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
