I mounted the stereo in my 24 like Dave did.

Jayhawk one more thing to remember. Be aware that there are two tubes glassed down each side of the boat for wiring and controls. I didn't hit the one on the starboard side but had to do some trim on the port side because I didn't think there is one on that side. Also if I remember correctly mine were not the same heights so take a look forward from the engine comparment to avoid having to fit around those.

I'm very familiar with the tubes from installing the hydraulic steering and tearing out the old. My wife and I have gotten proficient at using the fish tape in the Superboat tubes. It should be a fairly easy deal to wire. The other thing I'd be concerned about, is I only have one battery. I suppose I'd need to add a second one for the stereo so as not to drain the starting battery. I hate cutting holes in my boat. I cringed when installing the tab indicators. I had to cut a big hole for that. The stereo and speakers will be even bigger holes!
