Free Car audio what should i get?

Congrats every thing helps. Iam not a stereo guy but heres what i have found for mine. Pioneer makes the kick plate speakers set up for our cars 189$ for pair. Get a good all around deck that pushes your mids ok has hd radio sat ability and usb drive. Use the plate for under dash 4x10 to turn it into 2 4" speakers a member on hear sell the adapter cheap and put 2 good sounding 6x9s in the rear and give them a little boost with small amp if need be. I dont like the retros but thats me you can build a under the dash box for your head unit. I think Crutchfield sells a unit to mount stereo under dash to floor. My truck got boat speakers for door and kick panels so water wouldnt mess them up they are polkaudio i got the pair for 20 on clearance they sound great to me.
