[QUOTE="audiolife, post: 7247766, member: 541383"] Depends on a few factors, if your lights are dimming do the big 3 upgrade then play the biggest bass song you have. Do the lights dim at the beginning of the bass note then catch up while the bass is still playing? If so its a slow regulator, if it continues to dim I would check the grounds. If it still dims it could be the car's alternator or battery or could be a car equipt with the ever lovely Electronic Load Dection put in place to eek out the last mile per gallon out of your car. 650 watts might not really need an upgrade 1500 watts should get about a 70 to 100 amp larger alternator that does over half its rated output at idle. If you add a second battery and it is an agm you will want to check to see if your electrical is keeping up by checking the resting voltage of the batteries 4 hours after running them. Should be well into the 12.6 to 12.7 volt range measured at the terminals with a DMM. [/QUOTE]
