I have an inline fuse on the cable running from my battery to my amp. My amp is 750Watts and for some reason that fuse keeps blowing. Usually it's when I play a song that hits really hard, but tonight it blew on a song with hardly any bass. Whats the deal here? Nothing is shorted out and everything is hooked up correctly.

Double check your power connections and make sure you have a clean, solid, and short ground.

What gauge wire are you using?

5 gauge.

outtamymind

how big of a fuse do you have in your inline. and how long is your ground wire?

5 guage means your probably using a Schose kit. right?

X2 to the fuse size and ground length

Also what do you have it grounded to.

It might be something is loose, the bass rattles it loose and then it re-connects, If even only for a fraction of a second it will still blow a fuse.

If you are using a Walmart wire kit, ditch it, evey last part of it. Before you **** up something. I cannot stress this enough...Wires are the most overlooked but IMO the most important part a system. Building a good system boils down to delievering good clean power, if you are using sub-par wires, then your already at a disadvantage and the power hasn't even got to your amp yet. You could have the best equipment in the world but if you use cheap wires then it won't live up to its potential, and its quite possible that it will burn your car down

i agree with spun about the wiring. unfortuneatly until the OP responds there's not much else we can do to help him in regards to possible suggestions.

It's a 32V 30A fuse and the ground wire is about 4 feet long.

I ordered a 4 gauge kit from kicker. Hopefully this solves the issue.

outtamymind

personally i would bump that fuse up a little bit unless someone else know's something i don't. but cut your ground wire to under 3 feet to get the best grounding results. and ya that kit should do you nicely. what kit do you have right now or did you piece it together?

Codyak Supercharged

30a on 5 fkn guage.

**** we use 30amp on 10g

outtamymind

ya i can't remember what mine is that i use. its a dual inline fuse with i either 40's or 60's on 4 gauge wire

kkanowitz

Good choice.

I'm only running 300 watts and have 4 gauge wire. Some may say its overkill, but I'd rather not have my car burn down.

x2 on the ground.

jschatte

does the amp have a fuse? if so is it 30A as well?

brickloaf

ground wire should be less than 3ft

quest51210

so, everyone was judging on the amp kit before asking for specs on the amp? it is ridiculous to believe in "750watts". what if its a pyramid or volfenhag amp? which 750 is the max rating and rms may be 200watts. in which case a smaller lead wire and small fuse may be ok for the application.

there may be other underlying issues.

Doen't matter what amp he is running, **** wires are **** wires, and electrical current will still look for the easiest way out. That being said if the amp is a Pyramid or an Audison, if the wires are **** with no insulation, there going to short out or not be able to handle the current and could start a fire.

To the OP
I have a feeling that a 30amp fuse was to small for the amp, and good choice with the 4 guage kit, it should come with a decent size fuse and solve your problem. The fuse on the power wire should be at least the size of the fuse thats on the side of the amp.
Also the Ground should be no more than 20-30" in length, and the ground location should have continuity with the battery ground to avoid ground loops. Depending on where your amp is I suggest one of the bolts that hold your antenna bracket in or the actual bolt that your battery is grounded to.
Make sure to sand, or buff and paint off from around the ground area to provide a metal to metal contact

quest51210

**** wire and no insulation...the problem with **** wire is that it usually has more insulation than wire.

Ok so the kit should arrive today or tomorrow but I have another question. Keeping the ground wire less than 3 feet would mean that it's too short to reach the ground the battery uses. Is there an alternative grounding location you guys know about thats safe to use?

ya anywhere there's metal without a gas tank underneath... hey quick question your not using the stock battery terminals are you?

outtamymind

if there is one guy on here you want to listen to about car audio its emporer

baddabang15

iTrader: (3)

Yes. I am.

EmperorJJ1

iTrader: (5)

thats your issue not the wire... give me a sec and ill show you what to do

outtamymind

what's wrong with the stock battery studs?

EmperorJJ1

iTrader: (5)

you cant add a ring terminal on them. otherwise they get all loose. what you need to do is buy a new one for the ground use the ground nut on the power and done. simple 2 dollar one from wally world or autozone.

My stock battery, actully the positive wire terminal from the car had a bolt sticking op from it for adding things on to the positive output. The piece that went on the positive post was a flat piece of metal, but at the end where it hooked up to the wires there was a bolt/ screw sticking up. I just used a 10mm nut (one from the stock sub) and attched it there.
Did not all the Cobalts come with this

yes this true...
