help with a pro junior

[wasabe19]

hi guys i've been reading other forums about people adding an extension cab to a pro junior. since there isnt a speaker extension jack. how do i go about doing this? the onboard speaker is connected to the circuitry through a quarter inch jack tho. do i just pull that out and connect it to a cab or something? thanks.

yeah u can do that.. pull the jack and connect it to other cab, but make sure the speaker impendence is the same . if onboard speaker use 8 ohm then ext cab have to use same 8 ohm. unless got impendence selector behind the amp. hope this helps.

-note - dont forget to plug in speaker (ext or onboard) before switch on the amp, otherwise the output trannys will blow..

hey keysersoze808 thanks for the reply. does speaker size matter? i have a 10" in mine will it be compatible with a 2X12 cab (or a 4X12) for that matter? haha.
