4 channel amp with factory headunit possible?

[RioDeColumbia]

So I have the factory Rockfordfosgate sound system and I am wanting to add more power to the speakers. So I was wondering if anyone knows of it is possible to run a 4 channel amp with the stock headunit? I know there has to be one set of RCA plugs on the back of it since the factory system has a sub, but I don't know if it is possible to add a 4 channel amp to the system on top of it?

No, the factory system has an amp using a custom connector. I don't know if it's using high level or low level outputs tbh

Alright, thanks for the info. I might just buy a better headunit then probably.

I'd call crutchfield to verify, but you may be able to use the universal inline amp that alpine sells.
