Your speakers probably are made for 6 or 8 ohms. to check, take out any of the speakers and read the back for the ohm rating, if it is more ohms, you need a more powerful amp.

SONY KDL-52W5500 red light blinking 13 times


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

You are def overheating, If the ohms rating of the subwoofer is too low it will cause this same thermal over heat. If you have 2ohms in sub and a 4 ohms stable amp, you will overheat. Check the ohms rating of the sub to make sure this is not the problem

Will the amp play 2 ohm speakers


If your amp has ability to play 2ohms, then it will play. It will play even it dosn't have the provision. It might cause damage to the audio output at certain level if volume level is increased. My advice is to check your amp. or read the user mannual for perfact usage. Thanks
