AMP Earth Wire HELPP!!!! Plz:)

[Rob.]

here we lol
i got 2 400W Amps (1000W Peek). running 2 1000W JBL Subs. crusing down the sea front music up (Setting off some car alarms ) and i smell burning looked at amps and subs and notice the earth wire on one of the amps was melting the plastic that separates the Earth connection and amp remote turn on

can any one help plzzzzz other amp is fine!

 

[recaro182]

What exact bit is burning mate, as the earth and remote wires definately shouldnt be touching each other? What is the earth wire grounded to?

 

[spike]

not good mate.... post picture of your connections

 

[Rob.]

i will try post pics tomorrow its dark now lol they will just look black
the Remote thingy and eartch isnt touching theres a plastic bit inbetween them that stops it touching thats the bit thats melting i will see if i can get a pic on google to show u

loose connection on the amp terminal

 

[Rob.]

 

[Dink]

the earth isn't tight enough or you got a dry solder joint

 

[Rob.]

http://www.megaupload.com/?d=L4EKKD6G i just went out and made a video of the amp. as u can see there are 2 nice clean termainals and the top one(Earth) is all black wit melted plastic. after i noticed it melted i cleaned all the connections for the earth and tighted it what else could i check

 

[Dink]

did the terminal feel loose? like metal bit at the bottom not the screw?

 

[Rob.]

the bit that the screw screws into is solid dont move.

 

[Rob.]

i got a feeling the Ring connection on the end of the earth wire that connects to the Termanal was getting really hot as its only melted the plastic ring connection was touching. still dont no why

 

[Dink]

might not be crimped on the the cable properly.

also just noticed you got two cables on the amp earth. what is the second on for?

 

[Rob.]

neon. but i didnt have the neon on there when it started melting so cant be that. i just used the Rem wire so neon turns on wit amps. ( dont no if its a good ideal me earthing it on that earth ??? ) i wouldnt think it wouldNT effect things but i could be rong




just thought if the amp is earthing out and a load of power go though the earth wont it burn my lil neon earth?

 

[Dink]

i'd move the neon earth to where it's earthed on the car

 

[paul_h172]

if its the earth cable is melting its getting too hot, get a thicker earth cable, also earth the neon properly as it wont help

yes id go with Paul and use a bigger cable.....
or dont turn it up so loud.. your poor ears!!

 

[Rob.]

i going to buy a bigger earth and i have moved the neons earth thanks for ur help

yes id go with Paul and use a bigger cable.....
or dont turn it up so loud.. your poor ears!!

thats like saying if u had a 14" penis dont use it cus the girl will shout to loud if u got it use it

Your earth cable should be the same size/rating as your positive feed..

Please say it is... ? :S

You should NEVER use smaller earth wire than power wire, as it has to be able to hold the same power that is being delivered..

 

[mat-nos]

could be the fact that the amps are just not powerfull enough to do the subs thus over heating and melting the terminals, get a bigger mono block amp and a quality fat wiring kit!!

you will then find you dont need to turn it up so loud to get good bass and then the amp wont work as hard!!

also what setting do you have the head unit on ie bass level/sub level if it has one!!
power caps and a clio diesel batery may help too

 

[Rob.]

head unit bass is right down.

it isnt working hard vol is only on 17 and thats loud enough

there same size

 

[Brasseye]

if there is heat it generally means a poor connection or underrated wire causing a high resistance
