Need help on basic stereo for \'72 K5 I need some advice, I am putting on the soft top this weekend and tested the stereo with my shop speakers and it works OK. I want to buy some speakers this weekend to go with the CD/rec. which is an OK Kenwood. I was thinking some cheapie wal-mart pioneer or like 6x9's in those wal-mart boxes for the back and replace the dash speakers with similar type but I guess 4". I want to know if I need an amp for any reason and the best way to wire this in a 1st gen. with no carpet (rhino-lined). Any suggestions are appreciated.
