I am trying to use Rockford Fosgate T1650s component speaker setup. The 6.5 midrange speaker does not fit flush inside the fairing speaker cavity. The speaker magnet seems to be hitting the inside of the speaker box cavity. These speakers look a bit smaller than some of the other speakers like the infinity kappa 62.11 that a lot of folks here use. Are the speaker enclosures on the 18 RGS different than the 15 RGS. I think I had more room in my 15RGS.
