Mono amp install wire and fuse

[uenjoymyself]

Hello to all!

Installing a entry level mono amp to drive a 10" sub in my daughters car. I have 0 experience with car audio. The amp is a 1100 watt 250watt rms to a 350 watt sub. I have ordered a 4 gauge wire install kit. The power wire has a fuse.

Question: what determines the size of that fuse? Is it the gauge of the wire or the electrical draw through the wire that dictates the size of the fuse?

Do I match the power wire fuse to the fuse size in the amp?

Thank you in advance and please excuse my ignorance!!!!

AGU you'll just want to put the biggest one you can find in. Usually 60-80A, it might not work if the amp is drawing too much.

Thanks! Whats the remedy if a 60-80 doesn't work?

What causes the amp to draw too much?

I'm probably over reacting but I don't want her car to go up in flames!!!!!!

If it doesn't work you'll need a Mini-ANL type holder with a 120-150A Fuse.

I have read on this site and also been told by several members on here who seem to know there stuff that you always fuse for the wires capacity not the draw so in your case 4g I would think would be much higher than 60 or 80amp. Just my .2

u should do it for the power draw.....but most Anl fuses can take more then they are rated for....
