[QUOTE="revrad, post: 8804998, member: 686452"] I have a 2012 Impreza 2.0i, the lights dim a decent bit when my sub hits at/close to full volume. Trying to upgrade to a ~220A or so alternator to fix that, my stock 110A one isn't gonna do it for a 1000W Class D + 250W Class A/B. Already did the big 4 upgrade with little to no improvement in dimming. I was about ready to buy a brand x, then saw a thread where a few people were saying their alternators didn't seem to actually "turn on" until above 1000RPM, so their idle voltage would be like 12v with the engine running. So I'm kind of scared away from them unless someone has any further insight on that. Open to other options... I'd of course like to save a little money if possible but I know not to just go with whatever is cheapest without researching. Thanks in advance [/QUOTE]
