My Kicker amp isn't but around 4 months old has worked great in the past. Tonight I went to get into my car and noticed I had no base. I took at look at the amp and it's flashing RED and Green. The Sub is getting power but not very much, it isn't hitting like it should. (sounds about like a factory setup would sound) What are a few things I can try?
Do you have an electrical meter? Check the ohms of the subs coils. If they are 4 ohm coils, then the reading should be close to that. 3.8 or so. Also, check what the voltage is at the amp, and at battery. Should be the same, around 13.5-14 volts. Ohm out the amps ground wire. should be close to 0 ohms.
