Hey everyone, I bought a new amp and 10" sub for my truch and had it professionally installed. Everything worked great for a time and then one day the amp stopped working. Sometimes, after I had shut the truck off for several hours, it would work again but those times got further and further apart. Now, it mostly doesn't work. It didn't work for several weeks and then one day, it worked. It worked for about three restarts of the truck and then hasn't worked again for a couple of weeks. This same thing happened in my last truck. Is this a common problem or is it just my luck? Is this how amps go bad? Thanks in advance for any insight on how to correct this.
