Right now I am just running my components off the sundown 100.4d. I am about to pick up a sundown 1500d. I don't plan on using all the power but I will pair it up with an FI Q or some other sq sub. Do I need to upgrade my electrical? or will I be ok? I have a kinetik 1800 already under the hood. I am guessing I would be cutting it close. but what do you all think?
