I'm having some problems with dimming and almost feels like the car is cutting out when i have my system cranked up, I cannot find any information on doing the Big 3 for my car and i'm looking for some advice on how i can fix this issue. My power cable on my battery has a built in fuse and i'm not sure what it is for. I'm running a SA-10 pushing roughly 1k watts to it. I just put a duralast gold battery in right before i installed the system. What are my options for upgrades?
