at the moment I'm running some old school quart 6.5's q series with the qm 200.2 crossover and the poly switch keeps kicking in at high levels has anyone ever ran into this(cutting out on tweeters)? I was thinking about removing it from the board and replacing it with a low amp mini fuse or light bulb that will burn out at extremely high levels vs. the poly switch getting hot after a few minutes and cutting in and out as it cools and heats.
