Can I loop "RCA out" to "RCA in" on amp?

[Slick71ss]

I have a 4ch amp with 2 sets of line in RCA jacks and one set of RCA line out. My head unit only has one set of line out RCA jacks. So, after hooking up the RCA from head unit to the amp, can I run a RCA set out from the "line out" on the amp to the open "line in"? I drew (don't laugh at my art skills) a diagram below of what I'm talking about.



Would this cause any interference or other problems? I realize I won't have a fade between sets of speakers, but not worried about that.

My advice would be to get a y-splitter.

OK, just was trying to save a trip to the store.

If the amp has an RCA out it should have a switch to allow you to run all 4 channels on a 2 channel input without a splitter.

Yeah, check for that first. The simplest option is usually the best.

And that looks really bad....I would definitely do a splitter before I did that, haha
