Double Check Speaker Measurements

"First I would like to say that these adapters are well made. But unfortunately I am not able to use them by no one’s fault but my own. I recently got some Utopia M8s and was really excited to get them installed in my truck. When placing the order, I misread the dimensions of the Utopias and they will not fit in the slightest. So please double check the dimensions. If your speaker fits though, you will be happy with these adapters."
