Neo_frog Posted April 24, 2010 Report Share Posted April 24, 2010 Well just because you tune to a certain freq doesn't mean you'll peak there. When I tune to 32 I peak at 36, and when I tune to 30, I peak at 32 as an example. It's all about your cabin. Try tuning a bit lower (reduce port area) until they match. That way you'll be maximizing your cabin gain. Quote Need an install? Hit me up.[email protected]Got car audio questions?

Neo_frog Posted April 24, 2010 Report Share Posted April 24, 2010 So you're peaking at 55 or at 48? If you tuned to 40 and peaked at 55, then tuned to 55 and peaked at 48, then you should go slightly lower to match them up. Quote Need an install? Hit me up.[email protected]Got car audio questions?

Neo_frog Posted April 25, 2010 Report Share Posted April 25, 2010 Where are you metering? Your tune won't always be the same as your peak. Quote Need an install?
