Re: AMP TECHS - Can a coupler be used to extend speaker wire?
are you talking about hard wiring a female 1/4" jack the the combo amp, in order to connect it to a cabinet? because that should work fine. if you're coupling two speaker cables together, that should be fine too. although if this is the case, it would be ideal just to have a longer speaker cable. but as long as the connection is secure, it should be fine.
