Re: HELP! Installing sub, what do i use if no rca output is there?
low level is for RCA pre-out connections, high level is for speaker wire from HU to amp connections. it doesn't have anything to do with the frequency. I suggest using the low level, it keeps your install cleaner. you usually can run your RCA's and high level to regular speakers at the same time. at least I am with my HU.
