m get a jbl gto 1201.1 gonna run the amp at 4ohms and it puts out 787w rms at 4. I have a 95 ram 1500 i think it has a 120amp alternator. I am going to be doing the big 3 when i install it do you think my stock altenator will power this amp without dimming lights?

 

Highly doubt it. Add a second battery to help out.
