I put a pair of 6 x 9's in the parcel shelf because my 1995 Corsa 1.4 LS didn't have rear speakers. You do need a fair length of wire as you do have to take it from the back of the Head Unit through to the boot, you have to try to hide the wire as well. I don't know how to do this properly but I threaded my wires under the center console either side of the gear / handbrake, then under the front seats, under the mats in the rear, then each wire goes either side of the rear seat tucked down the sides, then finally they are threaded through the gap between the rear back rest and the seat cushion into the boot. Sounds really dodgey reading that back to myself but I don't know how else to do it LOL!! :laugh:
