In series (8 ohms) the current in amperes will be less
In parallel (2 ohms) the current in amperes will be more
A bb gun (8) , a 44 magnum (2)
An oak tree (8) , a piece of paper (2)
A punch from a small child (8) , a punch from Mike Tyson (2)
Make any sense ?
You can feed an amp with a small fuse with 8 gauge wire. ( Small child )
A mono amp with 4 big fuses you feed with 1/0 gauge ( Mike Tyson )
