I have a big 5 channel amp, running the Sub, front 6.5'' components, and rear 5.25'' Co-ax's, hidden in a false floor in the boot. I still have the jack and all that crap still. The spare wheel is there, although it will not fit over front or rear brakes
Under the spare wheel is a big lump aswell that cannot be removed. The Esc cossy boots are not as deep as std escort ones.
With this stealthy install , there is still room for pushchair and shopping!!!!
All runs off some Alpine headunit and multi changer.
