How to install speakers?

How to install Speakers in a 97' Jeep Cherokee rear pillar?

• I was wondering how to install two rear speakers in my jeep. I have factory speakers in the doors and back! The main reason Im asking is cause my rear speakers don't work at all! The two door speakers are ok for now but I would like my back ones to work too. I know the size speaker is 5.25 in. So how do I install speakers into the rear pillar?? Thanks :)

• Answer:

  all you have to do is find speakers the size that fit in where your old speakers go and its like installing home speakers. jut put the red wire to the + and the black wire to the -
