First, let me point out two things: 1) I am fully aware that this is a crazy idea (hence the title), but as most crazy ideas have been approached on TB at some point in time, so I thought it might be worth asking. 2) This is not meant to be a solution for gigging or as a main amp etc. The reason: I have a Rumble 500C which is plenty for all my needs when gigging or rehearsing. However, I own two small sports cars (one smaller than the other) and the trunk space is extremely limited, especially on the Roadster. I have been looking for small combos that I could fit in the trunk of the Roadster for when I choose to drive this car (sometimes I have no option if my wife is using the family car). The only options that I have found that will fit are the Rumble 15, various similar 15w combos, and the Ampeg B108 (which literally needs to be "helped" (as in pushed) to make it through the gap. None of these options are really shouting "buy me", as they will be fine for solo practice but not much more. The crazy idea: Take a larger combo (preferably used), with the amplifier mounted in a vertical orientation at the back, and saw it vertically in half, leaving the front part with the driver mounted and the back part with the amp mounted. Either by adding a small strip of wood on the inside, or by routing a joint in the cabs wood (if thick enough), it would create a joint that I could run some rubber stripping inside in order for the cab to be properly sealed when butted together. On the outside, I would add some quick release clips that would clamp the two halves together, creating pressure on the rubber seal and therefore sealing the cabinet. I would also add a connector to be able to disconnect the speaker when dismantling. I could also use a 1x10 cab with a micro amp, but the selection of 10" cabs is not huge (especially when factoring in that I am going to saw it in half!). So... Foreseable issues? Tips and suggestions? Recommended medication to avoid me having this kind of ideas?
