I bought my car with the audio sysem already installed so i'm not 100% on everything. But I have an alpine deck, Infinity powered sub, JL amp. The speakers I'm not to sure what they are.
so now onto the problem.
At random times my rear right speaker seems to cut out, then back in. This has started to happen more now that the weather has been warmer. During the winter it almost never happened. I checked the speaker connectios and they seem fine. I'm looking for some solid advice on how to trouble shoot this problem. I was going to take it to best buy or some local car audio shop but they charge something like $17 for $15mins...

thanks in advance.
