the head is a good unit if you got it for the right price.I would if it were my car try and find a good 5x7 to go back in rather than screw mdf spacers to my pride and joy. if you are going to run the speakers off the head unit you will find your left front and left and right rear speakers in the left hand kick panel which will be a set of orange ,blue &pink then run your powers over to the phone kit plug up under the right hand side of the dash (blue plug) and then your right hand side speaker in the right kick panel which is a set of greys .remember if you are unsure ask a shop cause airbags dont tickle and your unit should look like this
