Using External Amp Fuses ?

[scarolinablazin 10+ year member]

If you are running one I would fuse it at 200 amps on each power wire. Definitely put a battery in the back and use that for your d-block.

you saying 1 amp of fusing for every 10 watts?? is that where you get those numbers?? just curious as i`ve run 600+ watts on an underhood 30 amp fuse with no problems.

and also, it would be much better to have just 1 fuse if possible. get a blade fuse holder like you would use under the hood then a D-Block connected on the shortest piece of wire you can.

You are talking 600 watts vs. 3000+ plus. Different rules apply. And just because you have done it doesnt make it right. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

There are two inputs on the amp. You fuse each one. So not better to have one fuse. There should be a battery in the back to use as a d-block if running this kind of power.

either way, without knowing which amp you can`t or shouldn`t be able to give an answer that you`re 100% sure is correct. and why fuse them seperately?? when they get in the amp they are connected. which means if something goes wrong you have to hope 2 fuses blow instead of the one in my idea. 400 amps of fusing is 400 amps but 1 fuse is safer than 2

That's only because you never actually drew 600 watts, at least not long enough to blow the fuse. Fuses don't pop when you immediately go over the rated amperage. They gradually pop/burn as the amperage increases over the rated amount. 600 continuous watts on an excellent 14.4v electrical would be 41.6 amperes. When you fuse you want to fuse for your worse case scenario, running off your Bat at around 11 volts. If one's wire can't handle that amperage at that volt then they should upgrade.

There are two positive inputs on the amp. Is it really that hard to understand?

Also depends on efficiency of the amp. But yes it should be fused at absolute max current draw.

never drew 600 watts? wtf?? it was back in the day on 8g wire with stock alt keenwood 1021. it was 600+ watts crackin full blast. and worse case you would be better off going a little under that 50 amps over.

when this guy blows his amp from over fusing you`ll be to blame

guys, its not a zenon. actually, its not even a well-known amp and can assure you probably no one has one of these boards (not that its special or anything), so thats why i didnt mention the brand. here is the link a company that uses the same board thats in mine:

its korean built. i dont think the model is that important, since i listed the specs and the amount of inputs

You dont mind if I nominate you for r-tard of the month do you?

Bah, no it doesn't. It doesn't say in my manual that if you run the amp at 4ohms you need different external fusing.

You really don't understanding the Laws of Physics do you?

Everytime you lower the load of the amp, it draws more current, PERIOD, no questions asked. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Of course it does. But do you take out the fuses the factory gave you on your amp if you arent running it at full load? I highly doubt it. All it has to do is protect against a dead short, so fuse for max current draw.

LOL says the guy that answers a question not knowing the actual answer. even by you 1 amp per 10 watts he only needs 350 amps yet you suggest 400. you are the retard

wee todd it sofa king wee todd it

yea, cause if you`re running it at 4ohms and theres a problem you want it to start drawing more current than it needs before it pops the fuse. and what do you think will happen????
