Not sure if that would work or not. I know I really thought I had it figured out when I trimmed the adapter to to fit over those bridges and was totally bummed when the woofer hit it all the way around. I had the Titan rings for 6.5 and they are a very tough adapter ring. I might try these someday and see if they will work? I am actually pretty happy with it now, maybe a winter project.....

Does someone have the model numbers for the 4 channel amp, two speakers, and adapters? I am thinking about about two 6x9's in the future but I would like to start with this for now. Is there a contributor to the site that I should order from?
