Help to build a SW enclosure in rear seat

Hi all,

I am new to the 12volt.com and to fiberglass. I really need some help and advice. What I want to do is remove my back seat and put 2 subs requiring .75 cf  each in there. How should I go about doing this ?

For the background I have a 99 mitsu eclipse Spyder (the convertible). I already have a custom amp rack built out of MDF that goes in the place of the rear seat up/back rest. It is a very flush fit and very stealth. I would like to use the bottom seat wells and another 4 inches above to enclose my sub.

Any help would be very higly appreciated.

Thanks,

Jeff
