my battery

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...

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

hmm good point

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

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...
