Need help packing gear....dont have boxes no more

I could be going overboard here, but you might consider building a crate that would hold several pieces. It depends on the value of the equipment if it's worth it. If you are shipping by ground (it sounds like you are moving--just a guess). By ground it won't be as expensive and the crate will protect what is inside. In the crate should be lined with high density foam and then pack each unit in a cardboard box and bubble wrap. Any box can get crushed, but it's very unlikely a crate will. I had two very large crates built for my speakers when I moved. The moving company wouldn't insure them without the crates. The moving company also wanted $5000 for the crates, but I found a company that builds crates to make them for $200.
