Hi all--my combo amp, an old Crate B160XL, just pooped its pants for the last time. I'm hopefully picking up a Fender Rumble 200 at the local shop down the road in the morning. So here's my question--rather than pull the speaker from the Crate and sell it on eBay (a PITA) and dumping the rest of it, is there any reason I can't use the Crate as an extension cab? The Crate head unit is physically separate from the cabinet (it unscrews and slides out) and connects to the cabinet via an external speaker plug. So I'd just remove the fried head, get a longer speaker cable, and connect the Crate headless cab into the back of the Fender. The speaker in the Crate is a 15" Electro Voice Force. From what I've found online, it's 8 ohms and rated for 150 watts. Thanks for the advice!
