Kicker SX amp tuning question

Okay i just finished my first install of 2-12" L7's, 1-SX1250.1, 1-SX700.4, and 3 pairs RS5 coax. They are in a 2000 tahoe old body with the 5.7L

Im curious if there is anyone out there who knows what frequency i should tune the amps to, or how i should go about tuning them.

thanks in advance, ill post some pics later today.

I don't know how you're powering 3 pair of coaxials off a 4 channel amp, but basically the crossover settings should go about like this:  The sub amp should have the LP on, set at about 80 Hz.  And both ends of the 4 channel amp should be set with the HP at the same frequency...80 Hz.  Fine-adjust to your liking.  Each amplifier should be receiving a full-range signal;  however, the sub amp can receive a sub-out signal from the deck.  In that case you would still use the LP filter on the sub amp.

If your subs are in a vented box, use the subsonic filter as well at just below the Fb.

Also, if you need links or info on how to set up a CD with various frequencies for tuning, post up here and let us know.  I've got several prior posts (as well as others) giving info on how to set it up and use it.  Probably a good search through this forum's archives will reveal them.

thanks for the help, im powering the far rear left and right speakers off the rear left and right channels, and the 2 left doors on the front left channel and the 2 right doors front right channel. The subs are in a sealed box with about 1.6 cu.ft per chamber.  I have 0awg power wire distributed to 4awg which leads about 6" and 28 "  to the 2 amps.
