Question Logitech Z680 subwoofer

I was looking to use the subwoofer by it's self so I found this online today

use Z680 sub on an standalone amp's "Pre-out"? - Logitech Z-680 - Neoseeker Forums

about halfway down the page they show how to do it... Well unless I missed something I ended up blowing up one TDA7293 chip.

My input (RCA) in connected to the amp board marked Sub assuming that's right I can't see what else I could of missed.

And this happened...

I think a short caused it.. I was adding a input and I think the shield and the pin touched, but would the IC go out like that still?
