Amp powers up. the right channel works fine left not at all
My amp powers up and the right channel works fine but the left does not work at all. it doesn't work when i bridge the amp either which makes sense because of the left channel not working. i have checked all obvious things ie. power, audio signal input, different subs, checked reistance on speakers, taken it apart to check for burned parts. please help

If you didn't find any burned parts that would mean one of the buffer amplifiers before the power amp could have died. They could either be transistor based or opamp based. They are fairly low power so they will not explode like the output transistors like to do. Contact rockford, they should be able to send you a schematic. Let me know I will try to help you through it.
