Many thanks Carl mate, yeah it will take up a bit of room, Im going for the "JVC" install if you know what I mean as I have the 2 JVC speakers in front and the JVC headset wouldnt seem rite not goin the whole way lol
Im goin for one 10'' sub atm and will see how that goes and then depending on how it turns out and how many broken bits of trim I might go for another 10''
Will try and make a guide for future reference
Thanks again
