I could use alittle help with the powering for my car's new system. I own a 2005 Jeep Grand Cherokee Lardeo, and it comes stock with a 160 amp alternator and 760 amp battery. I made these current changes to the system; replaced all of the 6 stock speakers with Kicker KS line, replaced current amp with JL G6600 6-channel (75 watts RMS x 6 at 4 ohms at 14.4 volts), added 2 15" Kicker L5, added Kicker Kx1200.1 mono-channel for subs (1200 watts RMS x 1 at 1 ohm), added 4 selenium ST200 (75 watt RMS at 8 ohm) speakers on the outside and finally added Sony Xplod 2-channel amp for the seleniums (125 watt x 2 at 4 ohms). the car use to be in Florida but now is experiencing the cold of Indiana. my alternator has began to lightly squeak and it can barley be heard through the cars speakers. my question to anyone is what should i be adding to help out the power to my system (extra batteries, bigger battery, bigger alternator) or would i be alright to run the system without any additions? im hoping that this is not overloading my alternator and that it will not die not soon
