Alright, so here's the situation, when I bought the car from its previous owner, he told me that his son used to have a sound system in there. He told me he took it out and put the stock speakers back in and that they didnt work (the back speakers). For like the first month I think, they wouldnt work, and then randomly, about 2 weeks ago, the back speakers were kicking, and they sounded good.
I turn off the car, and then turn it back on a while later, and they had stopped working. The past week or two though, they've been working most of the time. I know my right, door speaker needs replacing, and I honestly have no clue as to why the back speakers sometimes choose to work. I 've talked to a few people, and this is what I got back:
Since the right door speaker is bad, it can effect the back speakers.
One of the back speakers may be bad, which is causing them to come on whenever they want to.
The connection is loose.
Now I definitely want to replace my stereo with a new one, but if the back speakers are working and the problem isnt too big, I'd rather just replace the right door speaker and buy a stereo instead of buying all new speakers.
