Do factory car amps have fuses?
Most amplifiers that have internal fuses use some type of automotive fuse. These are the same type of fuses that are used elsewhere in your car, and other audio components, like your head unit, may also use very similar fuses.
What fuse does an amplifier use?
These fuses are available in current ratings between 10 and 80 amps. AGU fuses can be used to protect the main power wire of small to moderately high power systems. They can also be used to protect amplifiers capable of producing up to about 750 watts RMS….
| Wire Gauge | Recommended Maximum Fuse Size |
|---|---|
| 16 awg | 7.5 amps |
Do you need a fuse for an audio amplifier?
While most car audio amplifiers do come with their own fuses, these fuses are designed to protect only the amps themselves. You need to install a fuse at the battery to protect the power wiring, your car, and yourself against fire, in the event of a short circuit.
How does a fused distribution block work on an amp?
Often this is done with a fused distribution block, so each amp gets its power line fused as it’s split off from the main power cable. This makes it so that if one amp suffers a catastrophic short circuit, for instance, the damage will not spread to the other amps or your main power cable.
What do you need to connect an amp to a factory radio?
You’ll need one for the amp’s input and the other for its output. These cables will act like a “T-harness” to connect your amp to the factory system. Behind the factory radio, you can access all of the speaker wires in one place.
Can a factory speaker be connected to an amplifier?
For amps with more than 75 watts RMS of output per channel, it might be better to go ahead and run new 14- or 16-gauge speaker wires directly from the amplifier to each speaker. Factory speaker wires are very thin, with high electrical resistance. They can cause noticeable power loss when higher wattages try to get through.
