I have a Markbass cmd 121 combo and matching ext cab. My question is can I leave a speakon cable connected to the extension speaker output in the combo while not attached to the other cab. when I use the combo alone? Keeping the cable attached would help me store it in the combo and when I do bring the other cab it's easy to hook up especially in a dark room. I know I might sound pretty lazy but this seems convenient as long as leaving the cable attached doesn't effect the amp?
