i bought a ragin cajun for my superchamp xd? but i have no idea how to put it in... do i need to take out the tubes?
If you can't get to the speaker without taking them out then yes.

There is usally two wires going to the speaker one - and one +. take them off, unscrew the speaker, put the new one in and attach the wires.

I put one in mine. I did have to take the back panel off to put the speaker in. Being the magnet is so much deeper on the cajin. Tubes stayed in. Good luck its a vast improvement.
