I took a little off the plastic surround, I don't want to take much off due to the intake mani being so close. I was able to just use one washer after a little grinding on the ring terminal. As long as the washers ok I'll make it work.
I don't have much of a system anymore. Just 2 type r's off a 2400db turned down way low. See my old "rearview mirror took out a chunk of my windshield" thread as to why. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif I'm doing this for the car, not so much the system. It struggles sometimes in the winter and figured since I already did the grounds long ago that I'd finish it. If it helps it helps, if not no biggy.
