Sounds obvious, but when you think about it in detail, what actually happens?
lets say I use 4G Wire for an amp that says it recommends 1/0G, The only difference is that the 4G will have a higher resistance. That would mean the Wire might get hot? but is that likely?
What are the actual problems of using wires that are too small?
obviously i am thinking this not because i am going to use too small a wire for my amp, its just that I ordered a 1kW amp but planning to use it at 4ohms, and its a pain to do the wiring again and I was wondering what would happen is I got lazy
