If your not using spare tire that would be a good place if they fit.
Im not using it I actually removed it today and I got a box put in there a few minutes ago with a Solid 10" speaker and I am very happy with it for now. I wanted the 2 12" speakers I have in there but didn't want to make a mess out of things after thinking it over.
