White housing cracked on a part that goes into a spot labeled r165. What is this part? Is it okay that the white housing around it is cracked? Amp plays fine. What causes this?

Best bet is to send it back to JL, they do not sell the PCB with all of the components loaded on it. Most likely the transistors in the power supply have fried. Open it up and see if you can find any physical damage. Google the part numbers of the bad parts, and you should be able to fix it relatively easily. www.digikey.com is a great place for parts. Read this for more testing procedure: http://www.bcae1.com/ampfail.htm The whole site is wonderful, really.
SOURCE: have a jl 500.1 amp
for that amp u need a compasitor to mantain the amps the amp draws the amp is being choked when the car is off and when its running its killing the cars charging system
SOURCE: jl audio 250/1 thermal light
i was having issues with this amp as well, the thermal light was flashing every couple seconds. i checked all the connections and i discovered that when i pulled the power wire out the thermal light was still flashing, which tells me that there was no power from the power wire, but it was getting power from the remote wire. i know this because it would stop flashing when i removed the remote wire. but wouldnt start when i didnt connect the remote wire but connected the power wire. so with the power meter i checked the fuse and it was a little loose so i screwed it back in and the amp turned right on.
to make a long story short,
a flashing thermal light is a power supply issue.
