thanks for the reply. i have 3 jl 6" subs (6w0). i was considering the Kinetik HC1800 battery, how about that one?

so an ecm can get hosed from a power spike, but also a power drain?

ok, say i add a beefier battery, cap, ho alternator (i don’t think i need this, just saying)…that makes juice available and on hand…don’t i need some sort of protection/regulation if that is the real issue with a clean signal to the ecm?
