Fuse Blew

[Xero.Limit 10+ year member]

I never really cranked my HU up all the way(35). Today I decided to try and I blew my Radio fuse on the car I think I made it up to about 32 or 33 on the volume before it cut out. That got me thinking how do people have even more powerful HUs and not blew fuses? Any info would be good knowledge. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Umm, what the hell? I have cranked mine many a times. Well not the one I have now, but other decks and never had that problem. Maybe try adjusting your stuff so you don't have to crank it that loud?

I just turned it up for the hell of it not an intentional reason really but when the fuse blew it got me thinking.

Yesterday a friend wanted to show me how his subs hit so we hooked them up in my car and I cranked it up a bit about 30/35 volume I believe. It played for a while then blew the same fuse again..I heard throwin a 7.5 fuse instead of a 5 helps out and stops the fuse from blowing. Anyone have any comments about doing this as far as safety and any concern?

You only have a 5 amp fuse on your HU? My van has like a 20 IIRC.

It's not the fuse in my HU it is the radio fuse on the car in it's fuse box.

Just run a dedicated power and ground from the battery and put a in-line fuse on the power.

not unless there is a short just put a bigger fuse but make sure it is not blowing because of a short i am pretty sure i have like a 20-30 fuse lol in mine

Best suggestion yet... Putting in a larger fuse is a huge mistake.

Unless it was the wrong fuse in the first place, Id just check and make sure its not shorting and pop in a little bigger one.

So I should go crank it up and see what it does to the bigger fuse? Is there any chance of this doing any damage to my vehicle?

check your manual and see if there is supposed to be a bigger fuse. most of them are ~20 amp fuses, 5 amps seems really small. DO NOT just throw in a bigger fuse than what was factory in the car, you are asking to overload the wiring that way.

if the factory fuse is supposed to be 5 amps, then just run dedicated power/ground wires with an inline fuse as mentioned earlier

check your wiring first before doing anything stupid. Putting a bigger fuse in is generally asking for trouble. Unless you already know it needs a bigger fuse.
