I am looking to put a 10" sub in my 2005 impala LS and wanted to know what the wattage on the factory amp is, and if it can power a sub or do i need a separate amplifier?

i was wondering this same thing, i think that the stock amp doesnt have a whole lot of power. but i could be wrong.

I would put in a seprate amp to run the subwoofer. The stock amp is not able to run the main speakers and a subwoofer together.
