subwoofer vs AI cell/pump
 

I'm currently redoing the full audio setup in the FD. reason i've posted in here is this: I eventually want to run a full AI system in the car. I also want ALL of my audio to be completely hidden.

so far the setup will be 2 sets of components/x-overs, amp and i'm trying to decide between 2 8" or a single 10". the original plan was to run them in a DamonB box that wedges under the rear strutbar, but that doesn't meet my goal of being hidden. So then we thought about a fiberglass setup in the spare tire location. unfortunately, that's also a PRIME location for an AI cell.

any of the gurus on here have advice as far as other locations in regards to running both? I'm trying to keep this a no compromise situation as well, the lower the weight is located, the better.
