My car right now consists of mostly nothing ... i got a Pioneer Head Unit DEH-P3500 and two 6x9 Pioneer 350 watt speakers in back with stock up front. My goal was to add some bump (eventually lol) Anyways .. i was putting my eye on getting a Rockford Fosgate 4 Channel 1500 watt amp to run all speakers and another Rockford Fosgate 1200 watt to run 2 subs in back.Of course like 2 Farad Capacitors. Well i didnt know i would have to add a whole bunch of other stuff to get it and my car to start n run. People told me to just buy a new alternator , but i dunno what kind i should buy or need ? Anyone out there know? and if i get a alternator what else will i need to get that to run ... like wires and any other hidden things ? If i get just a new alternator will this solve all my problems or should i just shoot this idea outta my ass ? Or does anyone know what kinda system i could make with a standard car without adding any power to the car itself . Like a standrd car can handle.... like what a 300 watt amp and maybe a lil sub lol ? i dunno im real lost in this whole issue if anyone would know anything it would be a big help.
