My 15 amp audio fuse keeps popping? I have no audio at all. All the fuses related to audio under the dash are fine, but the one under the hood pops as soon as i put it in. Any reasons why? I know my battery fuse is currently 120 amp only because its the biggest i could find to the replace the 140 amp fuse that was in there, but would that cause the audio fuse to blow? No other functions are having any problems. I dunno, not having a radio is starting to pi$$ me off. Any help would be great. thanks

 

btw, the 140 amp fusable link is 17 bucks from nissan, and i dont want to spend that if thats not going to solve the problem. Let me know what you guys think. thnkas

 

aftermarket stereo?

 

no, its the stock bose stereo

 

There has to be a short circuit somewhere in the audio system. The fuse is merely popping to protect the circuit. Have you changed any speakers or done anything else to it?

 

yeah yeah. that's why I asked about the stereo. if you haven't touched any of the audio or wiring then you have a major headache ahead when you try and find the short.

on the other hand, as kingrukus asked, new wiring or components would be the first place I'd look.

could it be around the rear speakers? I know mine have exposed wires in the trunk, so that would be a vulnerable place for the electrical. just a thought.

 

everything is stock. no replaced speakers, i havent touched the cd player, nor any of the wires for the speakers. thats why im just completely lost as to what this could be. i have nowhere to even begin looking

 

anyone??????????

 

like the other said, sounds like a short, check the grounds from the headunit and amps and see if the contacts are corroded or not grounding properly, or run a new grond ans ee if that helps

 

ok well here are some things to consider

was anything done near the firewall or anywhere wires run under the hood lately? if so maybe a wire got spliced...

water damage.. somethings shorting out causing excessive resistence in the line, thus popping the fuse...

you can try removing the radio (unplugging it) and then replacing it to see if it still happens... if it doesnt maybe there is a short in the radio itself, which i have seen on many occasions (not neccisarly with nissan's)

i run into these problems almost everyday at work, you just need to start working backwards...

 

try unplugging the stereo itself, i believe it has a couple of connectors, then put a fuse in, check if it pops. If it does, it's definately the wiring. If not, then plug one plug in, check if it pops, then the other and etc. Something is definately crossed. As someone mentioned, something somewhere could have just gotten rubbed off enough to do it.

 

I had a similar situation because my rear speaker was blown. I changed that 15 amp to a 20 amp and the problem stopped.

 

The fuse popping means there is a short or bad audio component.

If it's a BOSE system you have 5 places to look.

1) Left rear speaker amplifier
2) Right rear speaker amplifier
Both amplifiers are mounted under each speaker.

3) Right front speaker amplifier
4) Left front speaker amplifier
These amplifiers are mounted in the doors.

5) The BOSE head unit or CD changer (if equipped)

I doubt your going to find a wiring problem, if everything in your car is stock it's most likely a fried component.

Fuses are there to protect the wiring harness from damage from excessive amperage. You should NEVER put a higher amperage fuse in to solve a problem. You could burn up the wiring harness by doing that.
