I plan on mounting 2nd battery under my seat, true dual solenoid under hood and 4 ga wire to battery, 6 ga wire to fuse panel in over head stereo console. With that being said I want to put a circuit breaker in and am wandering if it should be under hood between solenoid and battery or battery and fuse panel? what I'm seeing in threads is it's mounted between the solenoid and battery. My way of thinking is it should be between the battery and fuse panel protecting accessories. Am I thinking wrong? Also should it be closer to battery or fuse panel? Was thinking under seat with battery.
