Where do you think I could find a box that is made for mustangs?
You kinda need 10" subs if you want it to sound good. 12" is too big.
In the original post it states that he has two 12" subs. So if you have one and it takes up your whole trunk, how is he going to fit two? NOT enough airspace!
It's a convertible man, no room!
i have been in the audio industry for years and have never seen a window break from too much bass(in a convertible)
I am fiberglassing 2 12" in a 2.6 cu ft box in the spare tire well of my 06 and will still have room above the false floor for luggage or s spare if i travel.
