need to know if I can use the stocks in the back which are 10 ohm with some 4 ohm fronts? I have a kenwood 5028 HU and just got the infinity reference 5010cs for the fronts http://www.crutchfield.com/*-phDVzMV...sp?I=1085010CS

heres the radio

If you are asking if you can keep the stock rear speakers with that aftermarket HU and use those speakers for the fronts??

If that is what you are asking, then yes you can.

yeah I was just concerned if the different Ohmic values would be causing havoc with my radio, its been a long time since my electronics classes

should be fine.

The ratings for the HU are the lowest ohm values that the HU can handle. Since the fronts and rears are on different channels w/in the headunit they wont impact each other.

I run amped 6.5" components for my front stage and the stock 6*9 speakers powered by the headunit for my rear fill. Other than my subs and the music I listen to reaking havoc on the 6*9 speakers they still work to this day.
