Aftermarket JVC stereo seems to have a bad connection.
I apologize in advance for the extremely general question but I'm having trouble finding this topic or the solution on the internet.
When I bought my car 2006 GTP it came with an old (but not too shabby) JVC KD-G140 stereo installed by the previous owner. It does the job for me and I'm pretty happy with it. However it's been having what seems to be a bad connection lately. When I'm driving down the road sometimes the stereo display will turn off although the stereo is still playing, and often the stereo will "lose connection" to the front speakers and only play the back ones. The display problem happens rarely and the speaker problem occurs often but both of these issues are simply solved by just pressing the faceplate into the stereo itself.
Now I'm pretty sure that the subs in the back of the car are stock. I'm not worried about those at all because they play at all times and sound great. The front speakers are aftermarket, which I have installed myself, and I know that they are working okay. Because these problems are solved by pushing the faceplate in it makes me believe that it is just a bad connection between the faceplate and the rest of the stereo. I've gone ahead and changed the fuse (literally did that 20 minutes ago) so I'll have to see if that helps but I checked the one I had taken out and it came back fine, I doubt that it's a bad fuse anyways but whatever...
I'm considering just going to Best Buy and having them install a new stereo unit for me. I know that I can do it myself but I don't feel like taking everything apart to put it in. Before I do so does anyone have any tricks or advice to try and fix this problem? Thank you so much!
