Jaycar 70A Circuit Breaker – Resettable, Gold-Plated Terminals, Car Sound & Audio Installations

Your sub amp just killed the fuse again. You're staring at a dead system and another trip to the shop. Stop doing that. This 70A breaker sits in your harness, takes the hit, and you push the button back. Done. Moulded in black electrical-grade bakelite so it shrugs off vibration and heat under a dash or in a boot. The 5mm gold-plated terminals make crimping clean and keep your connection solid over thousands of cycles. Rubber caps protect the terminals when not wired up, and the built-in test button lets you confirm continuity before you close the panel. Lower voltage drop than a fuse means your signal stays clean. Use it as an occasional isolation switch when you need to kill power to a zone without pulling a plug. One CTA: add it to cart and wire it in this afternoon
