PAC 2pcs RXE065 Tweeter Protector automatic poly switch for 4Ω 1" or bigger

PAC  Model RXE065
For 4Ω 1" or larger tweeters

2-Pack X065 Automatic Poly Switch
The RXE065 when put in series on the + speaker lead will break the circuit when there is to much current being sent to the tweeter.
This is not a crossover but a simple poly switch that will reset after 20 seconds of non-excessive amplifier power.
The switch adds less than 0.5 Ohms of resistance.
This is old stock but new product in older ugly packages.
This requires some skill to install because it has two stiff wires that must be put inline on the positive input side of the tweeter.
