Wondering if someone could help me out Currently my sub has only 2 connections. Line Out (Left and Right RCA), Line In (Left and Right RCA). No XLRs or anything else. Atm Line In is connected to my amps pre-out (a stereo preout, not a mono preout especially for subs) and everythings fine. If I wanted to upgrade to active monitors, would it work if I plugged in the Left monitor via single RCA to the Left Line Out on my sub, and the same with the Right monitor. Then have it all linked back to my amp (via the preout still)?
