For my 12v system im using a head unit and car amp to power the speakers.
Just checking it would be fine to wire it this way. I dont see why not? Im making a box to mount the amp and head unit in so would be easier wiring like this if its safe to! Rem = remote on Edited by Jack1991 - 11 February 2020 at 9:16pm |

The amp wiring kit comes with a inline fuse which i would fit too which goes on the positive cable to the battery. Would i need other fuses? If so where/what size/style please? I wont be running any speakers off the head unit. The speakers and sub will be off the amp. Edited by Jack1991 - 12 February 2020 at 9:13am |

Just an inline fuse will be fine.

should be fine, the HU will have a ~10amp fuse in the back of it.
Long as there's a post battery fuse, or in a fault/short situation the full capacity of that battery could be dumped somewhere it shouldn't = fire & injury (or the battery exploding on a real bad day) |

Id want a fuse as close to the battery terminal as possible. relying on the equipments internal fuses offers no protection in case of damage to the supply cable. whilst it possibly seems ott, its is a plausible danger. Actual real life, yes it did actually happen, example below: A friends car burst into flame outside his house (nearly took the house with it). it was a taxi and the mate that had installed his taxi meter for him had tapped the supply directly from the battery. there was an inline fuse but it was quite far downstream. the positive cable became chafed over time and shorted against the chassis. cue dead short with no protection and goodbye car |

right ok so this was would be 100% then? I dont need or should have anything else to add? The inline fuse would be the one supplied with the amplifier wiring kit. And be fitted within 1ft of the battery
This is NOT in a car by the way. Its just going to be a off grid 12v sound system.

As his diagram, the hu internal fuses are downstream of the inline fuse which, as you rightly point out, would ideally be close to the battery. Its also good practice to check all the cable routing to identify potential chaffing and protect the cable where needed.
