Boxster Battery discharge caused by Amp or Stereo

Recommended Posts

Hi fairly new to this but a great read so far and has helped me out a number of times!

I have a 1999 Boxster with a Becker SatNav head unit connected to Dash and door speakers via the Amp up front. Its all standard stuff.

for the past 4 years if i leave the car for more than 3 days the battery drains and goes flat, i just live with it! for the past 4 monthd i have been pulling fuese and quickly realised that if i took the "Stereo" fuse out i get no drain!! hooray i found the issue..... but i then disconnected the Amp up front (but only the smaller of the two connectors on the amp) put the fuse back and left the the car for a week and hooray no drain!! so i thought its got to be the AMP, i have replaced that AMP and you guest it th problem is still there.

So for now i just pull the hood and unplug the small connector block to the amp and the battery is fine.

My questions are?

Should there or is there a permanent live to the AMP? when i disconnect and reconnect the small plug i can here a click, so there is always power going to the amp?

Where does the amp get that power from? i thought it might have been to do with the old Ignition switch problem but everything else related to the ignition is fine?

has anyone else had this problem? any help would be greatly appreciated, not looking forwar to another Christmas of flat batterys!

Hi

I had a similar problem on my 996 carrera. I fitted a new stereo and found that there is a live supply to a detector inside the radio housing. Once this was taped up and a new stereo fitted, the problem was cured

Hi Thanks for replying, i looked back and can see my Stereo was indeed fitted as a replacement around 4 years ago and the problem has existed since then as well. Its a Becker Traffic Pro High Speed unit and works perfect. So do i go for the new Stereo or try to do what you did with the "Live Supply and the detector" what stereo was it?

thanks

Hi anyone else have any idea or help on this? i have since got a New Amp and still i get the same problem so it must be the live coming in to the AMP that is not turning off and draning the battery. Where does the live to the AMP come from??

Thanks
