[QUOTE="Jeffdachef, post: 8676093, member: 650438"] install a voltmeter, turn it up until you are dropping around 12.6 volts and you are good. If its dropping to below 12, you need to lower the gains. You dont need to worry about an alt with 1000ish watts into the system. Dont swap out speakers unless you plan on completely redoing the head unit situation with a DSP or head unit swap with a stronger 4 channel amp along with baffling, acoustical door treatments etc.... Stock head unit has stock EQ curve, high pass filters and sh*tty dacs which wont be anywhere half decent on aftermarket speakers and those speakers require something much more powerful than your factory amp.
