a couple times i have left my car lights on the interior to do some car audio install, and the message "low battery voltage" came up a couple different times. I had the lights running for like 5 hours. this was on two diferent occasions. Is this something to worry about, will i need to change my battery?

 

You should have the battery load tested to make sure it is ok.

Might be time to upgrade to an Optimun.

 

well, when my 500 watt sub woofer is running all the lights dim, including headlights, would the optimum battery eliminate the dimming? or is ther a better way to stop all the dimming?

 

Do you have a Capacitor? If not that would help alot.
The optima battery is like a Deep Cycle battery. It is harder to kill.

I need a Capacitor as well with mine on Volume 10 sitting at a light idleing I am not charging at all.

The Capacitor stores extra Voltage and doesn't take much from the battery.

 

actually ill bet getting a real sweet capacitator which is 1.5 farads and has a digital led blue read out, and it cost me 75 bucks with shipping and handling.... check it out ....

so this will eliminate the dimming for me?

 

That is SOOOOO sweet!!! I always miss DEALS like that.

Either they are expensive or I find them and have no MONEY. LOL

That should take care of almost all of the dimming.
