Help With Some Settings, Please

[alec_d70]

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.

Id leave the rear crossover off and run them full range to start.

If you hear them getting sloppy or bottoming out you can raise it up a little.
