I recently bough a 7" kenwood indash and i was wondering how i could go about hooking another battery to the dvd player so i can watch movies with out having to leave my car idleing for 90 minutes, and draining my battery..any suggestions would be great...

 

Why would you sit in your car for a entire movie? Just go inside. But you could just get another car battery and run two of them together, but then you will need a bigger altanator as well.

 

i dont know you could go up in the mtns. and **** around with a gilr or some ****....the only reason i ask is because i went up to mccall with this girl monica and we watched a movie and my battery went dead....

 

Monicaaaaaa!!!!!
Just let your car idel it doesn't waste to much gas, or get a bigger battery.

 

i heard it was bad for you to let ur car idle for long *** times

 

here's what i done in a mates motor (BMW, but the principles are the same)

i took a live from the battery, and ran it to the boot. if you have an amp power wire, convert this to suit, saving time. then i put in a split charge relay in the trunk, earthed to the chassis. i then ran a live fron the split charge relay to a caravan (trailer home) leisure battery, also in the trunk. this was also earthed to the chassis. you then power all amplifiers, head units, graphic equilizers, dvd players & screens from this. the only issue you will find is that you cannot use this setup and still have your radio turn off with the ignition unless you install a relay which switches a feed from the leisure battery to the ignition + in the main head unit, and is powered (or switched by if yo like) the origional ignition + feed already in the car.

 

ive heard of people using power wheel batteries for car audio. might wanna look into that. or ask the audio forum
