Do I need a specific type of 4 gauge wire for my monoblock amp?

I purchased a JBL BP1200.1 monoblock amplifier, for the subwoofers in my Cobalt. It did not come with any wiring. There are 3, 40amp fuses on the amplifier. I think that means that the power cable that I hook up to it, needs to have a fuse that is at least 120 amps. I ordered an amp wiring kit online, and it comes with an in-line 80 amp fuse. 

My question is, can I buy and ANL fuse holder to replace the in-line fuse holder on the power cable? And do I use a 120 amp ANL fuse, or a 150 amp ANL fuse?

As I read it, all fuses are on the amp.

If you want to be save, the specs say the maximum current draw is 113 A, so 120A would be acceptable.

Thanks for responding. So if I switch out the fuse holder from an 80 amp in-line fuse, to a 120amp ANL fuse, the 4 gauge wire and amp would be safe? I've never hooked up an amp to a car before, and I'm just trying to be as safe as possible.

Usually, #4 wiring kits are good for 2000 watts and can be used with a fuse block up to 125-A, so it would be okay. If I were installing this in my car, I would use something like the Rockford 1/0 kit with a 120-A wafer fuse, especially if I were cranking up the volume for extended period of time. If you go with the #4, install the fuse holder as close to the positive terminal as physically possible.
