Sub and amp wiring help?

i have 2 12" subs in a box wired parallel with a mono amp. i just got a new car and my ported box i have now wont fit in my new car. now i am going to be buying a custom fit box for my new camaro but the 2 12" box has 2 different chambers for subs. my question is how can i wire my subs parallel in this box so i can keep my mono amp and not buy a 2 channel amp. here is the picture of the box i am going to buy. a href="http://cgi.ebay.com/93-UP-CAMARO-PONTIAC-12-FIREBIRD-SUBWOOFER-SUB-BOX_W0QQitemZ270255162338QQcmdZViewItem?_trksid=p3286.m20.l1116" rel="nofollow"http://cgi.ebay.com/93-UP-CAMARO-PONTIAC…/a
