well the blose system is a TOTAL bust. i am hating it every time i drive the car and its time for a change. i need some advice!

im not super crazy about car audio, but i want something better. here is my plan, let me know what you think:

nakamichi cd400 head unit
metra dash kit/plugs
infinity kappa 60.5cs front components
infinity kappa 63.5i rear 3-ways
infinity perfect 10.1 sub in DIY box in stock location
alpine MRV-F450 5ch amp
good power cabling

any suggestions?

also, the box i calculated for my sub will measure 6.5"x10.5"x15.18" inside. i plan to use 3/4"MDF, good wood glue, caulk, and screws.

can anyone tell me if this box will fit in the area behind the driver's seat where my stock sub currently is? better yet, does anyone have rough measurements of that area? i might do a wedge shaped box if it would fit better/image better. id like the sub to fire forward.

is there enough room behind there to mount my amp as well? i dont want to lose the glove box. maybe i could go behind the glove box?

thanks all-
