Jessica Posted April 29, 2012 Report Share Posted April 29, 2012 I want to test my cars resonate freq. I have my 2 12's in a sealed enclosure right in the middle of the manufactures recommended volume. 1.25 cuft/side. if i play some tones and test the db/c would i be pretty close? All i have is http://www.amazon.com/USB-Digital-Sound-Level-Meter/dp/B005JX2EZ2/ref=sr_1_1?ie=UTF8&qid=1335727421&sr=8-1. I know they aren't very accurate, but i think it would probably be fine for this situation right? They are firing back into the hatch about 15" from the hatch, seems the loudest to me that way, a close second is subs up. I've tried them forward right behind the back seat, not loud, but not forward in the very back of the hatch. If you think i should move them closer to the hatch or further away that will be easy enough, and it's a 87 honda accord. Stop laughing dammit! Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside. My super random youtube channel and terrible camera work.

OrionStang Posted July 4, 2012 Report Share Posted July 4, 2012 I did like IH8punkrock recommended, sub in a sealed box. I played tones from 20-80hz, highest spl was at 36hz. This is my resonant frequency, I guess. Somebody tell me if I did something wrong. 2010 Mustang GT Trunk and doors deadened Tested with 12" sub in sealed box, sub up in the trunk. 36hz peak.
