System in my 81 mustang?

hey im kinda new to the whole car audio and am trying to learn.  I was hoping if someone could give me some pointers on how to put in rear speakers, sub and amp.  The cars a hatchback, so it has no trunk, so would i have to mount the sub and amp overtop of the spare or is there somethin else I can do?  Also, for the rear speakers, theres not really anywhere to accomodate them, so will i have to build a shelf for them or put them in a box or what??  any help would be appreciated.  thanks

Look at the possibility of going with front speakers, amp and sub.  A popular choice, and something for a well-rounded front musical stage, would be a 6.5 components for the front.  And one 12" or two 10" subs in a sealed enclosure for the hatch.  You can look through these threads over just the past few days and find a lot of suggestions on both.

The reason I don't suggest rear speakers is, the sound will be behind you.
