Hi there. I have a Rockford Fosgate P4004 amp and some Polk DB650 speakers in the rear of my car. Now for the questions. On my amp, what should I have the frequency settings for the DB650s? And also, again on the amp, should I put the rear crossover on AP or HP? I don't care about bass at all. If anyone wants to see the manual for my amp, go here:
Thanks to anyone that can help.
