I would say start with the easy and most sensible things, if you have a standard exhaust replace this with a more free flowing one which will not restrict the turbo, try a 3/3.5" mandrel bent stainless dump amd depending one your money situation chose the rest of your exhaust from there. I think ...

Like Red80 said you can adjust the boost with a bleed valve/boost controller. Just get a wastegate spring of say 7psi and add a boost controller to that.

You still will need a wastegate in a diesel situation as the pressure activated diaphram within it will regulate the amount of boost you will run.

I think you will find it hard finding a 12" sub with a magnet that will fit in behind the seat, (perhaps a cheaper brand SVC sub they seem to skimp on magnet size) you could just mount them as you suggested on an MDF board and use the volume of the enclosed area behind the seat. I dont know how this ...
