for the money your looking to spend i would HIGHLY recommend looking into focal speakers absolutely amazing so clear....as in a farad cap i would steer clean from this as it on stores and slowly releases energy to keep a steady current to properly set it up i would look into a kinetik battery....as far as subs kicker is whored out they arnt as good as they once were.....only their high end stuff is worth the time look into alpine type Rs very nice subs
