[QUOTE="Ramrod, post: 8355742, member: 639332"] I installed in a new head unit not long ago. I noticed my Amp/Sub didn't hit near as hard and the Gain control didn't do as much. No matter how I set it, it just didn't hit has hard. Anyway I think I pushed my Amp/Sub to much b/c a few weeks later my Subs surround blew.. Could a low RCA output voltage cause any of these problems?
