I'd like to buy a used SUB from someone on Craigslist, but I'm not sure how to check and make sure it's actually working.
Any ideas other than a visual inspection? Is there any test mode where I can hold down the power button or something like that?
I suspect it's fine but wanna make sure I'm not getting a borked unit and that's the reason he's selling.
Question
Buying used SUB - Can I test it without other speakers?
