I Have spent a lot of money as follows.

top of the line Kenwood head unit
Infinity Kappa 6.1 perfect components for the front 4x100 rms
Infinity Kappa 5.7 2 ways for the rear 4X55 rms
Rockford fosgate P8004 Punch Amp 4 channel 4X100 rms per channel

Seperate Amp for the 2 10 inch subs under the back seat. Working fine

Its all hooked up and I have a clue where to start.

The components have jumpers for high pass low pass?
I can set the Gains using the formula and A volt meter but
I have co clue how to set the cross over pots, Dont even know what they do?

I know this is a complicated question and dont expect a full tutorial but could someone point me in the right direction for information or give e a brief explanation.

I dont want to put the door panels on until at least I set the jumpers in the front Components?

Thanks in advance
