It would depend a lot on what type of subwoofer you have and it wouldn't be pretty.

According to the manual I found it doesn't have a Woofer Output so it isn't designed to route Low Frequencies anywhere.

Even if you rigged an Active Subwoofer to it using the Tape Output you wouldn't have central volume control for it unless the (unnamed) Sub was driven by speaker-level outputs from the Front A or B Speaker posts on the receiver.

Your question would be better framed and answered if we knew the details of the Sub and referred to ITS manual.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Why do speakers crackle and flash protect


Check your speaker wires. Make sure they are not touching each outher or back of the unit. This will overload your output transistors and shut down your amp.

STR de315 shows 'protection' after 10 minutes. Is this a common issue?


Does it still do this if the speaker wires are disconnected? The amp is protecting itself from a short on the output. maybe yo have a dead or distorted driver in one of the speakers. Also there could be a defect in on of the amp circuits.
