yeah true, that is a fair bit of room, but i'm running 6X9's and have a much bigger battery than that!!!
so needed to lift it up alot, i'll get pics today and post em here, it still needs some work, but it's getting there!!
also made one of these for a lancer too worked ok too!!!
as with the parcel tray fooey, wasn't too hard for me, just bent it up un the middle after taking the back seats out, just slides out!!
