    Adding a third sub/second amp, (battery help)

    With my current setup, my battery somewhat takes a beating. I can see the headlights dim sometimes, and often I see other interior lights dim when im pounding my subs. What would I need to do when I add my second amp and third sub to prevent the battery from not getting enough power? Someone mentioned a capacitor? Whats that do? Also, I heard putting a second battery in the trunk? How would I manage that so it would re-charge? Any help appreciated.

    But what would the battery in the trunk charge off of? Also, how hard is it to hook another battery up in the trunk?

    I think a new alternator may be more of a concern for you than adding batteries

    first upgrade the big 3...
    then get a yellow top...
    then add another battery to the trunk...
    then get a high output alternator...
    then consider getting a new car
