I check the voltage on my amp pretty often. Every time I check it lately the voltage age is less then before, but nothing has changed. All the settings are still the same and I use the same test tone. What could be causing this? I don't want my new subs messed up before I get to really use them.
Sounds like your alternator is possibly on its way out. When they go they perform less and less until they finally die. This would also mean that your power windows (if present) etc will roll up slower and ur lights may appear dimmer. Check those and see if anything applies.. Go to ur local Autozone they can check and see if ur Alt is still performing the way it should. Just some suggestions. Good Luck
have the amp repaired. it's probably the FETs in the finals, but it could possibly be the input stage of the amp, or failing capacitors, or the power supply failing.. I don't want to pin it to one thing without having looked at it. You can send it in for repair or just replace it, depending on how attached to it you are.
I'm planning to upgrade real soon. Would it hurt to keep using it? everything is almost set to max, but when I got it the gain was set a little over halfway and no bass boost. Doesn't seem to be clipping though.
