Hi, I have a '97 prk Ave and it has 9 interior speakers (1x3.5 center CH on dash, 2x5.25 2x tweeters on front doors, 2x3.5 on rear doors, and 2x 6x9's on rear deck. I also have a factory amp in back. What speakers should I get that are not too expensive but have good SQ, and how would I wire them to a Kicker 600.4 (if I can)
