I am going to be running a Rockford Fosgate 501bd Mono Sub Amp. I am going to wire my sub for a 4-ohm load and the amp provides 300rms at this 4 ohm load. I also have a brand new 1 farad capacitor. My question is whether or not to install the capacitor. People have told me that it really helps and others have said that it will actually work the alternator even harder because it has to store power in the cap also. Any thoughts?
