Speakers More Quiet On Left After Stereo Install

Just swapped out my old working car stereo receiver for a new one so I could have an AUX In. And no, I could not add an AUX IN with RCA cables on my old car stereo receiver. I did not change speakers. Black ground wire goes through harness and is not/was never attached to car.

Everything looks and sounds good except the left and rear speakers are noticeably more quiet than the right. Adjusting the balance helps compensate but I noticed that the volume must be above "30" to get decent sound. My car has the factory plugs. Original wires look good. I matched color for color between harness and wires for the new stereo. When installing I disconnected battery. I used electrical tape to insulate connections. I know I should have used twist-on and tape but tape can suffice if done properly. Only left over wires were a orange (power antenna) and blue (remote). Car doesn't have a power antenna.

Here are the rest of the specs. Any ideas???
