Sorry to have to post this, but I've done tons of searches and can't find much to help me. That said, I want to build a sonosub, but I'm a little lost. I have never done any DIY and I'm not very familiar with all of the technical language that I've been reading. So, I have two questions: Could someone offer a link to a good website or thread giving advice to newbie DIY'ers? I've started to dabble a little bit in the planning, but from what I've read, this is a lot more important than how I'm treating it. I've found winISD, and I'm experimenting with that, but some of it's confusing. What's important to take into account when planning? Also, the dimensions for the port and why they should be adjusted is confusing me. If anyone could help me out with this, that would be great.
