Originally I was having problems with my car starting(i would turn the key and no response, but if i held it in start for a few seconds and would eventually crank up) One day it stop completely and I found that one of my terminals was corroded and the whole positive side came out. So I replaced the battery and it worked fine, it even made my door speakers sound wayyy better with more bass. Now the situation is happening again PLUS the speakers have lost that power I had. The battery is only a month old now. Any suggestions?
