my battery

[DemonaL]

everytime i start my car, then i turn my head unit on, all my amps go on, and i start listening to my music and etc... so after 4 min of listening i shut it off got dressed, went to go out, start the car and it wont start...must be something wrong with alot of things but dont know what...

[Haibane]

were you on the accessory setting when you were listening to music? If so your battery is probably dead

4 min of listening shouldn't have drained it at all .... if the car was on or off

[Haibane]

hmm good point

[DemonaL]

i dunno why, the car was on, it was actually 2 starts bout 8 mins altogether, but i dont understand why the its suckin so much juice if the amps are off... i mean like i shut my air, and radio everytime i shut the car off, incase i am low, so the car doesnt need as much juice todo some other bs then start the car if im in trouble.

this is a good reason to have a voltmeter in your car .... in or near the dash. You alternator may not be able to keep up

[cody911911]

alternator may be shot and your battery didn't have much power and hereby when you shut it off it didn't have the power to crank over....

sorry i found the problem my dad fucked the relays up, it kept my sub amp on 24/7 so when i would come back it would be dead

hehehe swap out your 12 volt for 2 6 volts in series...2 times the amperes with out the worry of 2 12s paralelle draining each other...
