I was given an old school Rockford Fosgate 1001bd and 12 inch HX2 DVC 2 ohm. I want to properly fuse this amp at the battery and amp (no fuse on the amp) for my daily driver. I only plan on running the amp at a 4 ohm load (don't need to be too loud). Rockford recommends a 100 amp fuse (I'm guessing for both at the battery and amp), but would that be overkill if I'm only going to run it at 4 ohms?
This will be all hooked up to a Sony S310BTX HU.
Also, suggestions for a budget-friendly inline fuse holder and a new set of RCAs would be nice (Knu Karma?). I already have some RF 4 gauge wiring.
Thanks for the help
