i have i 4 gauge wiring kit hooked up in my car right now with a 70 amp fuse will i need a bigger one to run the jbl 1200.1 with two alpine type R 12's
If you dont have to permanently mount it for a trial run try it see if it blows.. the amp is only going to pull the full 120 amps at max load which should be well beyond clipping so if you dont push it that hard it may work..Just my thought..Personally I would use a bigger fuse especially if you intend to add more amps in the future.
I am running a planet audio 1200d to a 15inch type r @ 2 ohms and a p250 to my kicks and a 1 farad cap off of 4 guage with a 60 amp fuse and i havent toasted it yet.
