Are the door subs for shaker 500 on 05-09 "boxed" in the door? I just polyfil stuffed the Sony sub in my new to me 13 f150 and it made quite the difference, wondering can I do the same for the Mustang
It is sealed but it is such a small enclosure I doubt polyfill would help. Jl audio makes and 8" door sub that is a perfect fit though.
