12v Car Battery Setup?

  • What are my options? I Am trying to set up a duel battery setup for my Subaru brumby Currently it has a single battery and alternator. I would like to add a second battery to ensure the car can run all my Accessories (Sound Components: Head unit, Sony xplod 500w mono Amp, 6x 130w 4" speakers, 2 sony 1000w subs and 4x 6"x9" speakers.) All the audio Components run fine but when i turn on the spotlights/driving lights drains the juice pretty quickly. I was thinking of placing a 10 farad capacitor in the system and a second battery, but didn't want to pay $250AU for a duel battery setup. Can i just wire the two batteries in parallel and run the system off that or will it cook my alternator or have to many amps for the system to handle? Cheers

  • Answer:

    Wouldn't hurt to just hook them up parallel, diesel trucks do that stock. just make sure you don't hook them up linear, that will screw stuff up for sure. Also wouldn't hurt to up your alternator, or even add a second one. Have seen a few people hook up a second system all together. Run the car off on battery and alternator, and run the sound off another battery and alternator.

Take your alternator out and have it rebuilt to give it more output. P.S. Have ear plugs at high levels
