If you connect a 9V battery's pos and neg ends to the speaker terminals, you'll get that scratchy popping noise. I may be confused on what you're describing, but why are you expecting that touching new speaker terminals to old ones would result in more than that? Are you trying to transfer the signal from old to new with the stereo playing while testing?

I'm trying to figure out a clear way to test if the rear speakers are possibly blown which apparently can cause no sound from all speakers with the exception of the sub. I'm now obviously clueless as to where to test-connect a new speaker to to test.

I think you're over-complicating things. Just touch wires from battery to speaker terminals and see if noise results. If not, the speakers are blown. I don't understand why you're trying to involve new speakers in testing the old ones.

Previous commenter advised. Now the challenge will be finding a 9v battery

There was popping and noise when touched with batt

I would guess either your speaker amp is dead or something in the wiring has been cut then.

Would a Best Buy install of a new head unit bypass the amp?

They could either run new wire from the stereo to the speakers, which is pretty easy to do but less clean (i.e. more wires present), or tap into the stock wires at the stereo and bypass the stock amp, connecting straight to the speakers. Price would be pretty similar either way.

I have a very similar issue, after a long carwash or heavy rain. All my speakers will go out except the Sub, eventually it seems to come back to normal after a day of not using them LOL.
