Alright, so I have this JL 500/1, and I just put in a new 8w7 and hooked it all up and it was pretty quiet, so I went to adjust the input sensitivity as described by the manual.
So I get it all setup, and even with the gain all the way clockwise, while running a 50hz sine tone, I am still only getting around 5.5v on the sub output terminals. It's supposed to be up to 38.7v for a 3 ohm sub.
I don't know too much about this stuff, so does anybody know is this a problem with the amp/amp settings, or headunit problem, or bad RCA's?
I'm using an Alpine CDE-126BT headunit.
