Is it better to keep my Sunfire powered subwoofer continuously plugged in or if I know I'm not going to use it for three or four days, should I unplug it? I'm trying to make it last as long as possible. Thanks for any advice.

Does the auto-on feature work reliably? If so, it shouldn't matter if its left plugged in. I switch mine on and off using the sequenced outlets from a power conditioner. It goes on and off just like a power amp.

Do you have reliable surge suppression in front of it? If so, it really shouldn't natter. If not, get some.
Thank you
Constantly switching equipment on & off can lead to higher failure rates - the heating/cooling can cause mechanical defects in chips/transistors bondwires. I only switch equipment on/off once a day. Professional kit tends to be switched on and left on, however that uses power. Equipment failure follows a bathtub shaped curve, so if you look at a product the initial failures occur soon after manufacture, then failure rates remain constant for years, then the failure rate starts to increase as the kit ages.
The manual for my Denon sub(s) says not to leave it on for long periods. YMMV.
Agree with Duncan. Temperature cycling causes more aging. Just leave it alone and enjoy it
