General Wiring Question

[TheDesertFox 10+ year member]

I just have a few quick wiring questions.

I have a 800 watt system, so here are my questions.

1) From the battery to the fuse block, what guage of wiring is the best? 4?

2) What size of fuse should i use in the fuse block? 50 amp?

3) What guage of power wire should I have runnning from the fuse block to the amp? Same size as before or smaller?

Thanks boys, this is my first system so I thanks ya's for all the help you can give me.

same size wire through out your power wire. i assume you are running 1 amp and not 2 of a distro block? 4 gauge will be fine

don't need 150 amp for 4 gauge wire. 80 amp agu would be fine

when fusing that is the completely wrong attitude to have. if there is a short or your wire gets too hot and melts, you'll have serious problems. bigger fuses don't mean you'll be louder.

even with higher than needed?

lol i know it doesnt make anything louder, its just that i fell more secure when I have a Fuse that support more amp than needed, thats all...

150amp is the max I would go with on 4gage wire.

80-125 Would be best

Same relative question with different specs.

I'll have a Yellow Top in the trunk while running stock under hood for now. Running 1/0 AWG from front to back. I know 4 Gauge would work but went bigger for future possibilities. Now I need two in-lines on the main 1/0 AWG run.

What fuze size should they be? 100A 120A 150A 200A?

Running two JL Audio amps. 500.1 and 300.2. The 500 needs a 50A and the 300 needs a 40A inline fuse. These will be 4 Gauge off the rear battery.

Thanks for the help

On the 1/0 gage wire fuse it with 250amp or 300amp fuse.

Dang that seems like alot! I'm not doubting you but is there any recommendations on the lowest fuse rating to run on 1/0 AWG to a second battery? I was thinking 200A. Would that work or will that restrict the amount of power flow to the rear battery?

Thanks guys, so a 80 amp fuse should be good then. O and Iron, i love ur avatar. BB saved that day indeed //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
