Hello fellow bassists. I have a question. I have a hartke 215 cabinet that runs at 400 watts at 4ohms. Now if i wanted to add a 210 cabinet that handles 200 watts at 8 ohms how would i do this.? i am running on a peavey markVII head at 350 watts at 4ohms right now. So would i have to get another head and run the 210 off the extra head. My question is the 2 cadinets are different ohms so i am thinking i would need 2 separate heads to run both cabinets together does this sound right? How do i bridge 2 heads together by the way I have never had to do this before.
