I have a shitload of 8ga wire but my amp needs 4ga. Could I just run 2 8ga wires instead of 1 4ga wire to the amp, and then use 2 8ga wires for the ground also? Thanks
Hmm...it wont be exactly equal to the 1 run of 4 guage wire but it would be close enough I would think. Alot of more experienced people can tell you better than I can but from my knowledge I think it would be ok as long as you could run the two 8 guage wires without any problems.
Also I forgot to ask...What amp/s do you have btw? Them I might be able to better answer your question. I need an idea of how much current demand your going to have.
What ohm load will you be running the subs at....if you will only be running 2 ohms to the amp which is 750 watts supposedly from the hifonics bx1000d then you should be fine. Even if you were to run the amp at 1 ohm I still think you would be alright with the two 8 guage wires. So it sounds good to me man.
