[QUOTE="Idec Sdawkminn, post: 1958937, member: 569344"] First of all, what should the crossovers be set to?

Fronts are [URL="http://www.infinitysystems.com/caraudio/product.aspx?ProdId="]Infinity 4 x 6 Kappas.[/URL] The rears are Pioneer, but I don't remember the type or size. The sub is a 12" JL Audio.

I have them set for: LPF: 160 HPF: 90 I set them that way because from 80 to 160 Hz, they are low, so I wanted some overlap. Should they be different? I turned the gain on the sub all the way down, set all bass/treble settings to 0, and set my SW-Level to 0. I set the volume to be 80 dB at 1 kHz. 80 dB is counted as 0 dB in this chart.
