Why Would a Car Amp Blow Fuses?
Considerations Always use a wire slightly higher than the amperage that it is intended to handle. An 18-gauge wire should be used for 10 amps or fewer. A 16-gauge wire should be used for no more than 15 amps, and a 14-gauge for 25 amps. Anything that uses 25 to 40 amps on a continuous basis should use 10-gauge wire. It is also important to point out that the longer the wire, the more resistance will be incurred. Wires should always be just the right length and with just enough slack for movement. This will reduce the resistance and improve performance. Handling Amperage Loads It is not uncommon to see much larger amperage demands in audio systems. Stereo suppliers have much larger wires with exotic metal cores to accommodate these needs. Always read the package for the maximum amperage loads, and add 25 percent for safety in the case of a loose wire or short. Always use a good grade of connectors. Bad connectors, loose wires and shorts will blow car amp fuses. Power Supply Alternators
