Just a quick question. Could a bad earth cause my battery to become NEARLY flat? IE the car would only just start.

 

I ask because i put in a 12inch sub off an amp in on wednesday, the car ran fine on thursday and i left it at that and went away for the weekend. Come back on sunday to find that the car will only just start and the sub is only just working, it is very quiet. I play around with the gains etc but nothing helps. I get round the corner and the car just dies, start it up agen and it dies another 100 years down the road. So i take the inline fuse and and dissconnect the live from the amp and the car runs fine.

 

I spoke to a friend who sed a bad earth could have caused this. So i have re-earthed and will be going out for a hard drive later.

 

Amp is a Kenwood KAC-823 (1996 i think) along with 12inch Competition kenwood sub. Bridged at 2 ohm is giving 150RMS. Amp has a 25amp fuse in it. Im not sure about the inline 1 but all these have worked fine in a Micra and a 100nx.

 

Cheers guys

I take it its a dedicated live wire to the amp and not spliced into anythin else ?

 

When i got my car the amp was wired into the bloody cig lighter - and the amp kept cutting out due to not enough power

 

If it is a dedicated line it sounds as though earthing is the problem !

Yes its a dedicated line straight from the battery with an inline fuse about 20cm away from battery.

 

like i sed i re-earthed last night and will try it later on.

 

Cheers for that Chopper, i just needed confirmation that it was more than likely a bad earth.

A bad earth could cause these symtoms.

in extreme cases you could even set your car on fire

Yer iv heard about the setting on fire stuff.

 

Glad to say just been out for a blat and its workin great now.

if your running big ampage why not get yourself a deep cycle heavy amp battery....that way you wont need any kind of power cap for when your stomping out the tunes.....they arent cheap but a good one last for years im sure bob could sort you out with a good price on one

Yer i had a look at the yellow and red top optima`s their 150 quid though.

sounds a lot but you will be glad you did and they last for years.....you could also try out the talkaudio.co.uk for sale section theres some awesome ice stuff gets sold on there for very little money
