great video! the reason why you have a fuse is because in the case of a short circuit in your car, the fuse will blow therefore stopping the current from continuing to short fuse and possibly burn down your car.
often times the cheap power wire kits come with CCA wire and its super small gauge wire with large sheath around it. best to get ofc wire but for this setup it may not matter much.
Yes ! alot of amplifiers will release a chemical smell when barely being used which is normal because there heating up for the first time, however mine does over heat especially in hot weathers , they will randomly turn off then go back on , i would recommend checking wiring, first 2 times i found that a power cable was being crimped and my ground was weak , but now its simply because there getting hot in the back , i need a fan to blow on them so they maintain cool.
