Our High-Current ANL Fuses safeguard your high-powered audio systems for ultimate protection. If you have a high-powered mobile entertainment system in your car with multiple amplifiers, using appropriate, properly rated fusing is critical for safe, reliable performance. Also use ANL fuses to protect your vehicle electrical system from the possibility of unregulated alternators. Use an appropriately rated ANL fuse / fuse base between the output side of your alternator and your vehicle's power buss.
