Thank you, I now have the ports and can finish building the cabinets. I'll admit I'm a bit nervous about building the crossover. I've only done one before and it was for the tri-trix, but that had a helpful instructional video. I think based on doing that one I can translate it for this crossover, but if anyone has a photo of a finished ART crossover I'd love to see it. It would be a great guide to make sure I did it correctly.
