ive heard of putting a battery in the trunk if i wanted to play music without the car running. now wouldnt the battery die after a short while or is there some way to run to run the charging system back to the trunk. if there is a site that can help me out, a link would be great. thanks

 

You would have to hook it up to the alternator...but all in all, I would not recommend it.

 

y not just put the car in acc or on but don't start it

 

i tried doing that but the car wouldnt start after 1 minute of it im running 3 amps by the way off a duralast gold

 

wattage???

 

Doesn't matter...just don't do it. You are going to be throwing your money away.

 

1500, 600 and 400 watts
