Subwoofer Amp, Not Turning Off ? (1 Viewer)

[keithTa]

I have a cerwin vega 12" power subwoofer (not my choice) there is a problem with the amp not turning off. The manual states the amp will turn off when there is not a signal going through the RCA cable, but it stays on RCA connected or not, receiver on or off. Will there be a problem if the amp stays on all the time?

Thanks

1. Contact Cerwin Vega for an exact answer

2. Unless the amp runs hot, you probably do not have a problem. Use your good judgement how much heat is excessive.

3. According to a recent reviewer at Audioholics or Secrets, most auto-off circuits do not really turn the amps off anyway -- they just disconnect the amp from the driver. So the amp idles all the time anyway.

4. See 1. above.

Also, some amps can take 20 or 30 minutes(or longer) to cycle into "sleep" mode...so be sure you are giving it enough time.

You don't want it to shut off as soon as the signal is disconnected because if it did, then it would go to sleep during quiet parts of movies. Check it after a while like Tom mentioned and see if it has shut off. Also to add to what Geoff said, what they mean by shut off is go into "stand by", not actually turn off all the way.
