res frequency is 53 new box tuned to 64hz how much of a loss will I get in the car for tuning it higher?? Just curious, I have tested outside but not in the car yet //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif Im thinkin 3-4db's what do you guys think???

wtf do you have it tuned so high for? I think burping that far under tuning frequency is gonna give you a crap score..

Can't tell you an exact number. Only that you will meter much lower.

This is what im tryin todo, I burp at 53hz/res frequency with recent enclosure tuned to 46hz. Tested outside with recent and test enclosure and the test enclosure was 13 db's louder, Im just wondering how much Id lose in car?

Well the whole point of using the Res. Frequency is in car gain buddy...

so is 53 hz truly your resonant freq or is it the loudest note with that box? if its just the loudest note on that box you could be off on that.

Res frequency is 53hz and the enclosure peaks at 53hz im just wondering how much of a loss is expected tuning it higher. The transfer of the car jumps up at 53hz/res freq but its only like a 3 db gain from outside to in car. Is the 3db gain gonna be my loss??
