Ok so here is the deal I am going to upgrade to a 1600w rms Hifonics Goliath 15" sub with a 1600w rms Hifonics Zues mono amp. I am also putting in a Hifonics Jupiter 4 channel amp (600w rms). Do I need to upgrade my alternator/ battery? I have been told to upgrade my battery before but I dont knwo where to find these types of batterys.. any one.. a lil help!!
If your alternator can handle the load, then no need to do either. If it can't keep up, then upgrade it. You might want to get a 1.0 Farad cap for the amp running the sub.
