Installed front speakers and amp, lost rear speakers

[Lewshus]

I installed a new headunit (pioneer avh-p1400dvd) and front speakers. I left the stock rear speakers running from the head unit and hooked the front speakers up to a 4 channel amp (mb quart onx4.125). As soon as I hooked up the front speakers to the amp my rears speakers stopped working. I tried fading everything to the back and get no sound. My fronts work fine however.

any reason why this may be happening.

thanks in advance.

Double check that your connections are to the rear speakers and that they weren't connected to the front speakers by accident

Just checked that, all the connections are correct.
