Protect the power supply of your car audio system with our fuses and fuse holders for car amplifiers: ANL, Mini-ANL / AFS, AGU and various ratings for power cables, amplifiers and high-power audio systems.
The car audio fuse is an essential component of an amplifier's power circuit. Installed in a suitable fuse holder, it primarily protects the power cable against overcurrent, which can occur particularly in the event of a short circuit.
The fuse format must match the fuse holder used. The rating must then be selected based on the cable and the electrical configuration of the system.
The ANL fuse is widely used in car audio systems, particularly with large-gauge cables and amplifiers requiring significant power. Many ratings are available for systems of different power levels.
More compact than the standard ANL format, the Mini-ANL or AFS allows for compact power supply protection. It is used with many fuse holders and car audio distribution blocks.
The AGU fuse has a cylindrical format and is still used in many car audio systems. It is available in several ratings and requires an AGU-compatible fuse holder.
For high-current car audio systems, various high-current ANL fuses are available. However, the rating should never be chosen solely based on the amplifier's stated power.
The fuse holder must be compatible with the type of fuse used, but also with the cross-sectional area of the power cable. Our selection includes models for different cable cross-sections, as well as compact, waterproof fuse holders and solutions suitable for high-power car audio systems.
Find many ratings to match the protection to your wiring and electrical system.
The main fuse rating must be determined by taking into account the allowable capacity of the power cable, its cross-sectional area, length, conductor material and the electrical requirements of the system.
Not sure which rating to choose? Contact Sound Auto Concept with your amplifier model, the cross-section and type of cable used. We can help you select suitable protection.
Do not install an oversized fuse simply because the amplifier is powerful. The cable located downstream of the fuse must be able to handle the corresponding current. The protection should be placed as close as possible to the battery or power source to minimize the length of unprotected positive cable.
Always check the cross-section accepted by the fuse holder before purchasing.
Compact models may be suitable for systems using small or medium cross-section cables. Check the input diameters indicated on each product.
For large cross-section power supplies, use a fuse holder designed to accept the cable diameter. Some models accept a range of cross-sections to accommodate multiple configurations.
High-power, SPL and multi-amplifier car audio systems may require multiple protected circuits and high ratings. Each cable and branch must be sized and protected based on its actual electrical capacity.
The fuse installed on the main power supply primarily serves to protect the cable against overcurrent, particularly in the event of a short circuit.
The choice depends particularly on the cross-section and material of the cable, its length and the current required by the system. Do not choose the rating solely based on RMS watts.
The Mini-ANL or AFS is more compact than the standard ANL. Both formats require a compatible fuse holder for their respective size.
The ANL has a flat, screw-mounted format, while the AGU is generally cylindrical. They require different fuse holders.
The main fuse should be installed as close as possible to the battery or power source to minimize the length of unprotected positive cable.
There is no single rating applicable to all 20 mm² systems. The cable material, length, allowable capacity and installation conditions must be taken into account.
The rating must remain compatible with the allowable capacity of the cable actually used. An OFC cable and a CCA cable of the same cross-section do not necessarily have the same electrical characteristics.
No. Arbitrarily increasing the rating can remove some of the cable protection. First, identify why the fuse is blowing and check the sizing of the system.
This depends on the wiring architecture. When a main power supply is divided into several cables of different cross-sections, each branch must be assessed to ensure the conductors remain properly protected.
