Gotta love that mustang trunk! The convertible trunk is soooo awkwardly shaped.
The amps are mounted on a separate board that I carpeted and wedged on the left side of the trunk. It is screwed into the the trunk liner.
I'm going to screw down the woofer as well, probably with a 90 degree metal elbow screwed into a metal plate near the back of the trunk. I take the 'stang autocrossing and I can't have the woofer moving at all (even though it's wedged in there pretty good right now).
Beautify the android tablet head unit in the front with a with more putty, some sanding and paint.
All new suspension to lower the car about 2 inches and allow it to corner a bit better.
New wheels and tires. Possible 17x10.5 all around or staggered with 18x9 in the front and 18x10 in the rear (grip ).
New exhaust from the headers back.
And new speakers in the front and rear of the car (cheap but something that sounds nice and compliments the new woofer).
I would love to do WAY more. But I don't want to sink too much money into it. My plan is to spend only about what the car is worth, and since I got it for soooo cheap I still have a bit I can put in
