So I was gifted a sub off a mate which runs at 250W @ 4 ohms and just bought an amp, the amp is a Juice Ja1201d 1200W peak (I don't believe this rating lol), rms 480W @ 1 ohm, 380W @ 2 ohm and 225W @ 4 ohm. It has a 50A fuse on it.
I was trying to do some math to figure out what fuse I needed from the battery but I am struggling to find out what figure to use. If I use the supposedly peak power figure I do 1200/0.8 then 1500/13.8 is 110A which is way above the 50A on the amp this is why I don't believe this rating. If I do the 480W @ 1 ohm then this works out to be about 43A which is closer to the 50A on the amp.
Should I buy a fuse which is 30% bigger then the one on the amp? (this is what it recommends).
Also I just bought some 8 AWG OFC tinned wire for the power and ground and I am starting to feel I should have bought some 4 AWG wire instead :/.
My questions are will I get by with this gauge wire for power and ground and what fuse should I buy??
Sorry for this, this is my first install and am unfortunately really struggling lmao.
Thanks
