Hey guys, I feel like this is a simple fix, but I just can't figure it out. I recently swapped out stereos in my civic and for some reason, I can't get the front right speaker and tweeter to work. I figured that maybe I didn't connect the wires well enough when I installed it, but I set it up to where I KNOW the wires are indeed connected. They seemed to be working before I installed the new stereo. Does anyone have any ideas what I could be doing wrong? I literally played with the wires for hours and had no luck.

Is it a good stereo? Did you remove the door panel to look at the speaker?

Try swapping speakers--put the bad one where the good one is and the good one where the bad one is and see if the same door still doesn't work. If it doesn't, then you know it's the HU or more likely the wiring from the HU.

Upgrade your speakers.
