Good point. I guess no one will ever see the drilling. Going to try it this afternoon. It still fits flush after drilling, even though you are laying the speaker over the factory "3 hole" sections?
It almost sounds like your rear speakers may be connected out of phase, meaning the positive and negative wires on one of the speakers may be reversed. Try this... Isolate one rear speaker with your fader and balance. As you are listening, adjust the balance slowly to bring in the other speaker until it's in the center of the rear channel. If it sounds better when each speaker is isolated, and worse when balanced, then it could be the speaker wires. Not guaranteed, but it's a first step. Good luck!
Check out my photos, but the 4 inch speakers in the rear's polarity are reversed https://photos.app.goo.gl/2pibxMK6b4ESPHro7
They stick out about a quarter of an inch but fill the factory hole without any gaps
I could only get the left side to work with a self powered sub. I believe you would need resistors on the left and right channel which you spliced into for the sub. When I had both sides connected, the uconnect would not send sound to the right channel, when i did left only it worked. annoying to say the least but the resistors should be cheap
Ceramic 47 Ohm, 5 Watt resistors. One for each pair of inputs. If you have an electronics store like Fry's near you, they keep them in stock. Or, you could purchase them here: https://www.parts-express.com/47-ohm-5w-resistor-wire-wound-5-tolerance--015-47
****** THIS RESISTOR THING. I almost tore apart my Jeep again because I thought I had a bad connectionCeramic 47 Ohm, 5 Watt resistors. One for each pair of inputs.

The "Adding an Aftermarket Amp" thread has a diagram of how to solder it in, if needed. Good luck!
PS: You can test the need for the resistors by simply connecting the stock speaker back to the stock speaker wires and then turning your stereo back on. Once the stock speaker plays, you can disconnected it and carefully reconnect it to your amp, or your line output converter. If it needs a resistor, the sub will work until you turn off the Jeep. When you turn the Jeep back on (without the stock speaker connected on that channel) there likely won't be any sound. Can you tell I had major fits trying to figure this resistor thing out?
Any chance you can snap a quick photo of it installed up there? If the factory ones have the 3 hole, how are the 3 hole from the 4 holed aftermarket speaker sitting flush in the 3? The distance would be off to begin with no?
Basically you will want to use the "template" that comes with your speakers to determine the best location for the speaker. Then, pre-drill another screw hole (or two) so that they sit as flush as possible. You may have to use a glue gun to seal any gaps. There's plenty of room between the speaker and the covers on the soundbar.
