Box Info & Comments / Advice on my system.

Here's my advice to you son. Don't put 10's and 12's together. It won't sound great.

Really, what would you suggest I do instead?  What would be a better setup?  I can still get rid of what I have and get different stuff... so what should I do?

Its self adhesive I like to do it on warm to hot days and let the roll sit in the sun to heat up while im doing it. You need to get a roller and when you lay it down you roll it to press it into place. If you go to b-quiet they have instructions on how to do it. As far as the 12 and 2 10’ I would either go with all 10’s or all 12’s like TeeRizo said. If your looking for lots of bass go with 2 AW1208Q’s and 2 A18001D and I guarantee that it will make you cry. I have that set up and it actually sounds very clean but I have mine in a sealed enclosure.
