Autruche Posted June 22, 2011 Report Share Posted June 22, 2011 Are you using a 0dB tone on the head unit? and are all of the EQ settings flat with the sub gain turned all the way up?

Autruche Posted June 22, 2011 Report Share Posted June 22, 2011 Yeah, sorry. I meant the sub volume on the head unit. It's an alpine, so it should be like 0-10 or 15, turn that all the way up. when you scope it. You won't see full RCA voltage unless you do. Quote Need Test Tones/Sine Waves?

Autruche Posted June 22, 2011 Report Share Posted June 22, 2011 Well, that's just for the sub, I'm assuming that's what you were scoping as the readout says you're playing a 40Hz track.

bre2ts Posted June 23, 2011 Author Report Share Posted June 23, 2011 Am I right about there being no clipping at full volume? Just seems strange to me Quote Feedback 1 | Feedback 2 you win some, you lose some Link to comment Share on other sites More sharing options...
