If i was to run a radar detector,navigation system,and subs everyday in my car does that kill your battery???

Answer 1

It's really nothing to worry about. As long as you're not using massive amounts of power. If that were the case, the alternator would go before the battery.

Answer 2

The alternater "should" keep your battery charged up but if you are noticing a problem, you may need to check on an alternator that can keep up better with the additional drain of the electrical system since the one in it was probably designed without the add-ons in mind.

Answer 3

The radar detector and navigation system have very minimal power requirements.  Your sub amp definitely has much higher power needs so don't worry about the combination issue.  

When you car is running, your car battery isn't even part of the equation ... since the alternator is supplying all the juice.  Your battery has a limited lifetime expetancy anyways that won't change much due to your system and electronic accessories.
