Silver Member Username: Wolf_houndPost Number: 166 Registered: Sep-05 | So i ran a couple tones and the loudest in my car was 45hz does that mean that the resonant frequency of my car is 45hz? My box is tuned to 34hz is loud as h3ll already but if i build another box tuned to 45hz would it be louder would it be worth it? thanks |

I have been told my Blazer peaks at 46hz... which is also what i have been told my subs peak at.... so... perfect combo maybe? Im not sure if that is true.. but i have heard a few people say that it peaks at that.. Post a thread asking about Freq for YOUR CAR maybe sombody did the testing already in one.. |
