I have been having trouble with my car stereo system
After i installed a battery capacitor i started having trouble with my system just shutting off for no reason. After I go in the trunk and just move around wires it comes back on. what do you think could be the cause. Im thinking it is the ground wire not being properly connected but could that cause the entire system to shut off if not connected. I dont think it is a power problem because the radio still stays turned on, just no sound is playing. so maybe an antenna wire problem. please help. and could u also tell me how to properly install the battery capacitor to make sure that isnt the problem to begin with

Firstly remove the stereo system and see if that fixes the problem as if it started after you installed it then you have interfered with the power systems for the ECM. Best have the stereo system fitted professionally if that is the case.
you have a serious electrical problem. It is related to the stereo. Disconnect the stereo and hard wire the stereo system directly to the battery with an inline fuse. My spidey senses tell me you are in a german/ european car? Major elevrtoical issues/ design.
Does it have a SECURITY system in it ?
Is the SECURITY Light on or Flashing Sparatickly ?
Any Trouble codes ?
POSSIBLE - * MAF sensor (Mass Air Flow Sensor) has gone BAD causing car to start then shut back off . * Security has kicked in ( Due to changing stereo system or battery went dead or didn't have one on it for a little while .
FIXES - *Replace Mass Air Flow Sensor (in between the throttle and the air filter box) . * Take to Dealer and have computer Flashed/Reset if SECURITY is at Fault . I recommend the MAF sensor

Aftermarket stereos are designed to work within the power specifications for most vehicles, if you are experiencing blown fuses I would suggest re-checking the stereo wiring for a crossed, exposed, or improper connection. If you have ruled out all of these then you can install a capacitor to power your system more efficiently. Most car audio stores sell these and are installed between the connection to the head unit and battery. I hope this helps =)
some stereos will shut off if the voltage drops below 12 volts. measure your voltage at the battery with the car at idle and stereo turned up and all accesories and lights on. you should have 14.4 volts with the car running. the batteries voltage is 12.6 volts so you have to have more than this to be able to maintain steady voltage to your components. if the voltage drops too low when the bass hits it can shut off your radio. a capacitor can help this and the safe number is 1 farad for every 1000 watts. if you plan on adding any other amps autotek and phonix gold both make a digital capacitor that is compact and go anywhere from .5 farad to 10. the bigger the cap the better. if your voltage readings are ok then check that your speaker output wires are not touching.
You should be looking for a large capacitor to insert in the stereo's power leads. One farad, more or less. The CD shuts off when the battery voltage drops below a certain voltage. This prevents the voltage dropping below the threshold while cranking. Available at Wal Mart, Canadian Tire, Radio Shack type stores.

check your wiring in your vehicle to make sure that the yellow wire from the stereo gets "constant" power. It it what keeps your stereo's memory, and powers the audio amp in the stereo. If this wire is loosing power when you shut the key off in your car, you will loose all of your settings...bass, treble, tuner, clock, and also where you left off on your CD.
