Hey everybody, I just purchased a USED SAZ 1k on here. And once i installed it i realized that the blue l.e.d on the amp was not on. I checked the voltage and it was reading over 14v. Checked the grounds, power and it was all fine. I even swapped out the amp with TWO other amps and the others worked fine. (nothing was changed). The amps used were a Sundown 100.2, and Alpine MRP M1000. Now after trying one more time i was messing with the remote wire and saw that the PROTECTION l.e.d would light up from time to time. So i am guessing that the power l.e.d. is just out which is no big deal, I cannot confirm this because I dont have a working woofer sitting around i can test with. Also i checked the guts and couldnt find any unusal spots. The ground/power inputs on the guts side is tightly screwed in so that wouldnt cause it. MY guess is the led is just out. Reason for thread is just wanted to ask the previous owners if they experienced this problem as well. If anyone has any inputs let me know thanks Casey
