I wanna mod my Rumble 150 bass amp for a speaker output. I'm thinking I'd use the headphone jack, since I never practice with headphones anyway. But what I'm asking here is how could I wire it to where it would put out sound from the attached 15" speaker and horn, while also running into a separate 4x10 or something like that? Your thoughts, please.

It just needs to be in parallel with the speaker connection.
