[QUOTE="TaylorFade, post: 6833389, member: 618111"] I love this thing! I probably have the lowest numbers of any TL owner, but whatevs. I have been researching about how to find resonant frequency and I tried the method that was suggested and I just wanted a little feedback on what I found. I built a 1cf box for a 10 that I had laying around. It's a RD classic and since I couldn't find any T/S on it to be able to build a box with a .7 Q, I tested in "real time" outside the car first going from 37-67hz. Then I put it in the car and ran the same frequencies. The peak outside the car was 39 & 40hz. The peak inside the car was 42hz. The biggest cabin gain I got was +4.7db @ 43 & 44hz. Unfortunately, There was no pronounced peak any higher than that and I actually had a negative cabin gain in the mid-50's and low-60's. These were all done at a steady ~ half volume because I didnt' want to foul the numbers by the amp heating up or voltage drops. And the sub in the car was sub up in the driver's corner. I suppose I could run them again with different sub placements to see if that changes the results any, but what do you guys make of those numbers? And since I got it I have been going nuts metering every car in sight with a sub. Lol.
