Just installed my sound system. It's only small with an active 120w sub and an amp feeding out 2x100w.

I play a Cd at low volume for just 10 minutes and the battery dies!? This is without the engine on but 10 minutes with low volume! Something must be wrong?

If it means anything to anyone I have heated seats too but they were off. One chair isn't installed yet so dunno if that's casting anything.

I don't know why this happens! Any ideas!?

Thanks

 

OK so i'm figuring is a parasitc draw from either my amp or cd player. I haven't tested but this is the result of research.

I'm going to test the draw with the car off which I expect to be fine.

Then test with the key turned and I expect loads of draw. Then pull the headunit fuse and see if it goes down, if not then pull the amp fuse and see.

I watched a video and he said not to turn the key with the multimeter attached. Should I worry about this? How else am I to test the amp/headunit which only turns on with the key turned?

Thanks for any help.

Been a frustrating install!

Cr&p i'll probably just blow my meter up as it's only 10A, and you're not meant to turn the key as it will go over that.

How on earth am I going to test this as it only happens when the headunit/sub/amp is on!
