[QUOTE="c_hayhurst, post: 1909740, member: 555043"] I have a Rockford Fosgate T5002 Power Amp that is 2 years old and it has worked flawlessly until yesterday. It is driving one RE 12" SE sub, wired mono. Here's what has happened: It would cut in and out every 5 seconds. The amp is the second amp in a 2-amp daisy chain. The first amp works fine, which drives my four 6" speakers. The RF's power light comes on like usual, and neither the Thermal or Protect lights come on (which is a good thing). Then today, the sub won't run at all, while the RF amp's power light is on, but the Thermal and Protect lights do not come on. I disconnected the sub and checked the connections on the speaker and re-seated the speaker-wire connections on the amp. The sub still won't work. What else can I check to find the problem? The speaker wires aren't cracked. I have a multimeter that tests for DC, AC, amperage and ohms. Can I use this to test the amp? I loathe the idea to take the amp to a dealer and pay them $33 for a bench test. [/QUOTE]
