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?

Always put fuse closest to battery, especially if your running 4 wire, i would double up. I use 1 wire when installing subs.   I have seen plenty of cases where bad install, not fused up front , year later power cable rubs metal and then  call the fire department.   That fuse up front will stop this
Use a 120A fuse near the battery in this case..
