Is it possible to run my front and rear speakers on 2 of the channels in a 4 channel amp, and then my 2 8" subs on the other 2? The subs are 8 ohms, so I could wire them so the amp see's a single 4 ohm load, but I'm not sure how it would sound. I assume my front and rear speakers (4 in total) would have to be wired a certain way too, right?



Or would it just be better to run the front and rear speakers off of the head unit and then run the subs off the 4 channel amp?



This is my amp http://www.crutchfield.com/p_108R475...tp=35782&avf=N

Run all the speakers off the amp. Bridge the second pair of channels at 4 ohms on the sub. It will be fine as long as you hook it up correctly.

 

Amp front speakers, run rears off the deck and amp the subs but make sure the amp sees them as a 4ohm load or better if you want to go for the magic smoke effect. That should give you a nice sound stage.

 

LOL @ me . . . I haven't had rear speakers in my car since it was almsot-new and didn't think about your car having them . . . ^ what he said
