Front + Rear off of a 2 channel?

[pope]

Any cons to running your front speakers off of one channel and the rear off of the other on a 2 channel amp. Besides the obvious, being you'll have a little less control over the level of each speaker. I have some RSD65cs components up front. Some Pioneer Rev 6x9's in the back and a ZX350.2 amp to run them all. ZX350.2 is rated at 175x2@2 ohms, so all 4 speakers would see a decent amount of power, just wondering if the 2 channel will be fine or if I should get a 4 channel.

110 watts RMS x 2 at 4 ohms (175 watts RMS x 2 at 2 ohms

Run fronts off amp and rears off HU.

you could run them all off one channel if you want - you just have to watch out the way you were them - if each speaker is 4 ohms - then you could wire two speakers in parallel to the channel and it would make each speaker the same as a 2 ohm speaker. if you add the speakers in series then it would be the same as an 8 ohm speaker.

yeah - the way to calculate the resistance of a resistor (in this case the speaker) is:
if ita in series, then add up all the resistances. If its in parallel then add up the resistances and devide that number by the total number of resistors.
eg, if you have three speakers, wired in parallel, and each is 2ohms, then the total resistance would be (2+2+2) / 3 or 6/3 which is 2ohms. you could, technically add twenty 2 ohm speakers in parallel to one amp channel, and run them all
