Re: Amp keeps going into protection mode
Unfortunately, the fact that someone gets paid to do things isn't indicative of their expertise. A lot of professional installers don't know how to set the gain on an amp, so your amp could have been being over driven all this time.
It could be a blown speaker, which could also be caused by improper amp settings or it could simply be a loose or corroded power or ground wire.
If you have access to a digital multimeter, I can explain to you how to test your speakers but before you do that, go over ALL of your power and ground connections to the amp and make sure they're tight and clean... from the battery all the way tot he amp ground. And don't forget to remove the fuse(s)and make sure they're not corroded.
