battery draining?, or bad wiring or something? Options

[brianforster]

After finishing my stereo yesterday this morning I came out and tried to start the car and the car needed to be jumped.

After I jumped it, I shut it off and then turned it back on (the battery had no time to charge) and then it started right up. My step dad said that it probably wasnt the battery being dead if it started back up.

The battery is 3 years old should I just replace it and see if that solves the problem?

Also is running a power wire to the stereo from the battery a constant drain on it?

Whats the best way to attach a power wire.

thanks all

Running an amp wire from the battery to the amp is normal... check to see if your amp however is turning off when ur radio or car turns off via the radio's amp/ant turn on lead..

Your battery might not be able to handle the power, or one of your cells are bad. How many amps you running btw? if your running a few and their drawing alot of current your alternator might not be able to handle it and wont charge the battery enough.
