Looks like it!

Good job tracking the problem down. I think you found it.

BTW.... what is the amp that has the problem? Brand, model?
( I hope it's not a really expensive one )

You know, you can move that Pioneer Premier amp you have on your subs over to your components. That would be a better solution for them anyway.
Then just buy that Kenwood classD monoblock for your solobarics.
