Help with a home theater system issue

Long story short my roommate has a surround system she got at Goodwill and I set it up for her but the internal amps are not functioning properly. It's only using the front two satellite speakers and sub which is independently powered. So it's 2.1 for now.

The front two speakers barely put out much sound even cranked to max volume. The sub is fine as again it's independently powered.

I've ruled out all settings, as there is a 2.1 output mode, and the radio is just as low so it's not an input issue. I have it hooked to her PC's output. I also have proper gauge speaker wire so that's not the problem either. I did hook up the center speaker to one of the front outputs too. Same deal.

So can an inline amp help at this point? Is there anything else I can try or rule out?

Also if this is not appropriate to post here in Tech I apologize in advance.

    In this situation, I would first test the speakers with a known working system and test your current receiver with known working speakers. That will help identify which part of the system you have problems with, or both. From there, it could be any number of issues.

      Thanks for the advice. I tried the speakers on my stereo and they work perfectly. And then I tried my speakers on the faulty receiver. The same problem occurs. All of them are 8 ohm so it worked out perfectly for testing. Way too low. It's gotta be the receiver itself I'm guessing. I tried my phone out on the AUX input as well just to see. Same deal.
