I have a 4.600 cobalt amp that i wired 4 speakers into. A set of infinities 6x9's and a set of infinity 6.5. When i switch the amp to a 2 channel mode only the back speakers work, but when i turn it to 4 channel mode, only the front ones work. Anyone have any ideas on what could of caused this?

Are you using all 4 input jacks on the amp? If so have you checked the fader of your radio?

If the amp is working on the front and rear speakers, just not on all 4 at the same time, I would have to say that the amp is fine.

Yes, each speaker has its own channel and the fader is set to 0 just like all of the other controls.

I understand each speaker has it's own channel, but I need to know if you are using all 4 input jacks.

I am having trouble downloading the install manual from Orion's website. I will try do get it tomorrow. Until then, double check your speaker connections and switch settings on the amplifier.
