Hi All,
I have a JBL GT4-10 Sub, i'm looking in to making my own box for it, to go in the boot of the car.
i've been round and got various programs that work out box dimensions. but i've not a clue...the dimensions it gives me for the spec of the sub are strange, ie. the front face of the box, where the sub would be mounted, i have less than 20mm either side...
my maths skills are practically non-existant so i can't work it out my self, well won't because i'll mess it up =\
so if anybody knows what they're doing when working out dimensions....i'd be very grateful
