Need some help... Yesterday I replaced my front speakers with aftermarket 6.5's. Swapped the factory front into the rears to replace a blown original, and after working for 1-2 hours, I have lost all power to both lower and midrange speakers on both sides.

I replaced both rear actuators at the same time if that helps. There are no loose connections, or blown fuses, and I swapped out the amp with a loaner, and still nothing....

Any advice before I take it to a local stereo shop?
