is this normal?

hi guys,

I am running the following on my car,

6 X 9's Xplode 4 way 330W
6 1/2" splits Xpolde 200W
12" 1200W Xplode sub
Xplode head unit
2x300W RMS Channel Xplode Amp (for sub)
4x50W RMS Channel Clarion

Problem is, the battery gauge on my car now sits at 12V or just over when idling... it used to sit at around 14V... is this "normal" and am I going to have any trouble with my battery?!

Cheers.

Kieran.

Check the voltage at the battery with a multimeter. If its 13.8-14.4 then its all good, otherwise your battery will eventually stuff up. It could take anywhere between 1 month and 36 months....

oh yeah, its a fairly new battery... I put it in March, but the car was off the from april till a month ago... so i guess it would be fair to say its quite new... judging its run for 3 months/8000kms...

Ive got the same problem... the problem is with the alternator, not the battery. At idle your alternator isnt providing enough charge to run your electricals + audio gear. I was advised to install a capacitor but that didnt fix the problem.... next I will be getting a better alternator with a better regulator.

Yep eb_5litre is right - get yourself an EL alternator - I'm told they are 110a - if need-be cover all your bases and also look at an Optima yellow top gel cell deep cycle battery - 650 cca - designed for audio nuts etc.

Kypez, I recall you having an EF yeah ? - I think the EF I6 alternators were only 88a or something...but don't quote me on that - it's just something I heard in and around the place.

Cheers,
Steve

I'll post something up then... but I just wanted to know if there was any immediate danger... thats all...

cheers.

My latest replacement alternator is a Baxters 95amp...... when it dies I might go all out and get a Stinger 200amp jobby.

i dont see how a capacitor will give you a 14V charge when idling? They are to stop sudden drops in voltage, eg. headlight dimming from bass beats.


Also upgrade your earth wiring etc in your engine. Make sure the earth wire form battery is big enough, also engine to earth and sometimes people also change alternator wiring.
