Wiring 4 speakers to 2 channel amp
I have a good 2 channel amp however i have 4 speakers wired to it. Currently the left channel on the amp runs both the rear and front left speakers and the right channel runs both the rear and front right speakers. However as i have a sub, i want the midrange and treble to be comming front the front speakers more.
Can i wire it so that the left channel on the amp runs the front speakers and the right channel runs the rear speakers? Then i can fade it so that there is more comming out of the front speakers. I don't see how this would cause a problem although it may affect the way the stereo sound comes out.
Might think about that however...
I am looking at buying a 4 channel amplifier and feeding the front speakers and the sub though that and using the exsisting amplfier to run the back speakers so i can set a lower gain level for the rears. However will i not loose audio quality and will the power not split for the rears if the rear pre outs are split into 2 sets of pre outs?
Also whats the best high pass frequency setting for speakers if i have a sub (i.e. dont want bass going through speakers, however i do want the full midrange and treble going though the speakers for clear sound).
Another option i have is to get a set of passive crossovers and feed the rears through them. Or is there not some sort of volume controller i could connect to the rears?
