Hey guys,
In my current 03 GD3 VTi i have a self installed Alpine Headunit.
My freinds father (a automobile wrecker) has offered me a Amp + Sub.
so what i wanna know is...
Where would i mount the amp too? Remembering that the jazz has its petrol tank under the front row seats, where else could i install it so it doesnt interfere with the folding seats and that?
Also whats the best way to hold a sub down in the back? i dont go easy around the corners and i HATE things flying around in the car it pisses me off beyond belief.

any ideas be great. also any tips on hooking the amp and sub up would be appreciated too.
