ya, i just made a cut out of the profile of a kenwood xr-w12f and put it on the side profile layout of the sub box i need for the new seat, and i think they will fit,it will be close but i believe it will fit. the subs only require .8 cu ft recommended so its technically perfect according to kenwood. the cutout is as close as i could get from the limited dimensions the manual gives, but i made it a little big on all sides so there's room for error.its close on the back edge, less than a quarter inch, but it seems like it would work. thanks for all the advice. hopefully within the next few weeks or so ill be able to figure it out and build the box and install the new seat and be cranking the tunes!
but either way theres nothing wrong with just messin with the ol truck
Thanks Guys for all the help and advice!
