I blew a speaker not too long ago. I replaced the speaker yesterday. Plugged it into the Amp. Turned on the stereo and noticed that the speaker wasn't working. I looked at the Amp and the Power light is flashing on and off and on and off.... Did I ruin my Amp? I checked all the fuses... they're all good. What to do now? Please help

The KAC-624 is a 40 watt x2 @ 4 ohm RMS amp. 55 watt x2 @ 2ohm. 110 watt x 1 Bridged I assume at 4 ohm. Manual does not specify. It can run 2 ohm in stereo mode but is unclear on mono impedance requirement. It can run 4 ohm mono at 110 watt but at 2 ohm?
This amp is stable down to 4 ohms bridged at 120 Watts or 2 ohms stereo at 60 Watts X 2. If you are going with the bridged mono hookup just make sure the impedance of your subwoofer is no less than 4 ohms. A good rule of thumb is to be at least double of what your amps rated output power is. So if your amp can put out 120 Watts into 4 ohms then get at least a 240 watt subwoofer.
Do not exceed the rated load for your amp, you will damage it. Here is the datasheet for your amplifier
Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.
unplug all speakers and see if it still into protect .If unit powers up normally without speakers , then hook up a temporary speaker directly to speaker out to see if you have output.If it works .Then check speaker cables and speakers for shorts.Also make sure you have good ground and main power and standy are present.
