[QUOTE="RebelDogg, post: 4589976, member: 591498"] I'm putting a zx750 and a CVX 12 in my car Saturday. Right now I have a 4ga wire with a 100a fuse running from the battery split into two 8ga's for my zx400.1 and my zx250.2 The ZX250 running two 75wRMS componants. When I replace my current sub and amp with the CVX, I will be upgrading to a 1/0 from the battery split into a 4ga to the 750 and an 8ga into the 250, but the shop was out of a few things I needed to buy today (fuse holder, distro block, fuses...) and I had to order. I plan on just running it all on the wires I have now for a few days until my stuff comes in. My question is will the 100a fuse on the 4ga wire at the battery be okay? I don't know how to figure amps, but I heard the zx750.1 pulls about 85a. I'm not sure about the 250, but I would assume it pulls about a third of that (say 30a) which would be a total of 105a. Will the fuse blow right off? If it makes a difference, the 4ga is 17ft to the block. 8ga wires are about 3ft or so with a 30a fuse and a 50a fuse. [/QUOTE]
