Jaycar RXE185 PTC Fuse – Speaker Protection (Electronics Component)

That tweeter's been rattling loud enough to make you wince. Before it gives up for good, the RXE185 PTC fuse sits between the crossover and the driver, catching the overcurrent hit and letting things settle. It resets when the temperature drops — no soldering iron, no 6-day wait from a national chain. Check your speaker's resistance spec, grab the matching PTC, and get back to listening

• PTC (positive temperature coefficient) fuse for speaker protection
• Model RXE185 – match to your speaker's rated resistance
• Self-resetting: limits current during overloads, recovers when cooled
• Protects against blown drivers and shorted voice coils
