How long would my battery live with amps while the car is off?

[talnlnky]

there is no way of answering that question... soo many variables... here are some of the main variables.

battery fully charged/battery voltage
Volume of music
Are you clipping your amps
Type of music
ambient temperature outside
the size and length of your power wire
what type of fuse you use (Some fuses have high resistances)
Any other electronics on (fan, lights, windows)


If you're worried about it.... something that helps is to wire your subs to a higher ohm load... say you have two 4ohm subs... instead of running 2ohm, run 8ohm... you'll use 1/4 the power, and it'll barely sound quieter.

Could also get one of those solar trickle chargers... throw it on your dash and let it trickle charge your car so you won't lose a charge as fast.
