    Haha! Yes sir!

    I am just looking for opinions before I buy the 270a. I won't be running at full tilt very often at all. I won't even be demoing it very often. Just for me to work and back and on drives to the store, running errands etc.. The electrical is almost costing more than my subs and amp..

    Go with a 270amp alt and a 100ah battery, with 3500watts @ 12volts your amp will be sucking close to 300amps, say goodbye to your stock alt.
