B/A to Kicker

My 07 magnum came with the B/A system. A while ago I changed the amp to Kicker. I recently came across a complete Kicker system from a 300 srt-8 with the powered sub. any Ideas on hooking up the sub or do I need to trade for the magnum box or make one like it? It has the custom enclosure for the wheelwell of the 300. any ideas?

Actually you can go and grab a cheap 10 sub box from somewhere. and mount all the stuff on the new box. seen it done. Most audio places can give you a premade box really cheap. Or build your own. Either way it's how you want it in the end.

I think I'm gonna just get rid of the box & amp & just get one from a sound shop
