so i have an old 100 watt standel combo amp that sounds really good but doesnt have speakers. im running it through a 120 watt crate combo amp. i recently got a one-speaker cab and have another speaker to work with as well. I was wondering if there is a good way to combine the two combo heads the and four speakers into one big amp without blowing any of the speakers. if so, would it be 220 watts?
