Audio Systems: ohm load wiring., alpine v12, best bet

Question
I have an alpine v12 expert mrv 1505 amp (2/1 channel class ab) and i just picked up a 4ohm and an 8ohm SVC subs from a buddy for $20.00

how should i wire theese, and what will the ohm load be?

Answer
you cant mix and match ohms.  you should never mix and match subs that are different in any way, it will ALWAYS sound like crap. trust me.  your best bet is to check Ebay and see if you can find a match for either one of these, get it, and then you'll have a matching pair, then sell the odd one on ebay or to a friend etc.
