Maybe somebody can help. There use to be a site that you could plug in your amp size and wire lengths and all that and get what size fuse you need to run inline. I have been looking and I can not find it know. If anybody knows where that site is at please let me know.

Thanks

I would like to know if I have the right size wire for the install. It is Xsites 2000 MONO amp and I am running 4ga power and 4ga ground. The subs are wired 1ohm which is fine for the amp and I am running a 125amp fuse inline. I would like to know if this is going to be enough?

Thanks
Wade
