I am running infinity speakers with rockford amp.

My setup:

P4004 amp

one speaker to each channel (all rated at 2 ohm)

My question is; one pair of speakers are rated at 55W RMS and the others at 110W RMS that goes to the P4004 wich is rated at 4x100W RMS @ 2 ohm, do I have to set the gain on the lower rated speakers lower then on the higher rated speakers, so I can make it loud without blowing the weaker speakers?

Are you saying you have 2 ohm voice coils on the speakers?

The impedance is 2 ohm on the speakers.

Exactly. By having twice the RMS power available for the front speakers, you'll definately have to watch it with the gain knob. I recommend setting the gain on the rear ones first so you can roughly set it half of that for the fronts.

Always adjust gains slowly and you'll be good.
