where u plug ur RCA's into, the input may of burnt up, inside, or could be the same on the output side.
shit happens with amps that some cant explain easily, electronics VERY tricky. download your manual, or buy it, or find a shop with it, or read it if you have it. it should explain ALL combinations of protection light patterns. blink 1 times a second, 4 times a second, sustains for 2 seconds, flashes 2 times then sustain for 4 seconds, it depends on the amp on the patterns it gives out.
