I installed my friends amp and two 10"s w/ an 8 gauge amp kit. He recently Bought two 15" flame q's and i told him hes gonna need to get a larger gauge power and ground, and a circuit breaker. He blew the fuse in no time and i put a new 60 amp fuse in (a 60 amp was in before) then got 4 gauge power and ground. Once he turns it up to about 16 it will stop hitting and you have to turn it down a notch and it will hit again we are going to put a circuit breaker in (atleast 140 amp maybe 200 amp) and i was wondering if this would fix the problem. If not what is the problem and how do i fix it.
