Help with power loss

//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Okay, so I have a 460-watt amp, a 10-farad capacitor, two subs, four speakers, and a Pioneer head unit hooked up to my 1964 Ford Fairlane. I know next to nothing about car audio, so hopefully this'll be less of a problem than I think it is. Here's the deal:

I bought the capacitor (and switched my generator out for an alternator) in hopes of ending my initial problem, which was that my battery would basically slowly wither and die if I kept my audio running.

My problem now is that if I don't start the car up every 24-48 hours, the battery is completely drained. I also noticed that even after unhooking the negative side of the battery, when I took a wrench to unscrew the positive side and hit the frame of the car, sparks flew and the wrench quickly heated up.

I figure that somehow the sound system is constantly on instead of turning off when the car does, seeing as (thanks to the cap and alternator) I now never have problems once the car is running, only when it hasn't been driven for a day or two.

Sorry if that's not crystal-clear, but if there's any way I can make my scenario more clear to you, let me know. I'd just really appreciate a little help //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Thanks

 
Get rid of the cap and make sure all of your turn on wires (acc and remote) are wired correctly. Test with a dmm to make sure you have power where and when you need it and not when you don't.

 
The sparks from the wrench was just you shorting the circuit. The chassis of the car is a grounding point....therefore you completed the circuit from the pos terminal of the battery to the negative of the chassis.

if the negative post on the battery is not connected then there will be no spark(without the cap). the cap being connected to the chassis completed the circuit. whenever the cap drained, then the screwdriver would cool off

 
i know my shit bro . that is the prolly number 1 proble with old cars. i love them tho. upgrade all your cables to newer cable. and you should see a huge power gain. re wire everything realy nice too
