hey im new to this forum but been a mustang owner for a while, my current mustang is an 02 coupe. as of now i have a 12" sub sealed in my trunk. after christmas i want to go to 2 12" subs ported. it was hard enough 2 put in this small box, so i dont know how to put in two 12"s. i was thinking of trying from the inside but the from the trunk floor to the little metal hinge(connected 2 the firewall) that has the seat belt clips on it, is like 11.5", just a tiny bit to small. 1) is there any way to take that 2 inch surrounding piece of metal off, then put it back on? 2? is there any way to completely strip that wall and rear deck to get a huge box in ther. i mean i am lookin at a 4 cu ft box, so these r my options. if anyone has some good install pics or detail instructions or even some suggestions it will be much appreciated. thanks.
