4 Channel Amp
I'm new to this forum and this as the most related area i could find. I was wondering this. I have a Arc Audio Kar 400.4 amp 70rms x 4 channels at 4 ohms or 100 by 4 channels at 2 ohms. I have a set of ID ctx65cs comps up front and was wondering since the speakers are recomened at 100 rms if i could some how get the load to 2 ohms? would adding another set of speakers in the back reduce the load to 2 ohms ? if i wired all 4 speakers into 2 channels what would the power ratings be? would it beed 100x4 ? or would it be the bridge power ( 280 rms x 2) divided by 4 channels ?

You have 2 choices.....you could bridge the amp into 2 channels and be very careful how you set it up i.e. gains at minimum, Xover set to 90hz or so and the fader set back a bit to the rear.....or......get yourself a stronger 2 channel.....
If the set is rated at 100w/channel full range they will handle a lot more power if you take all the low bass info out of the signal.
Personally I would try option #1 first, you already have the amp and all that extra power will really bring those comps to life.....
