Has anyone used these with their own power supply? I have a power supply already, I’m not going to buy the 1000ASP just to power these.
No problem as long as the PSU meets the specs listed in the data sheet. I recall that ideally you have a low voltage supply of a little more than the +/-12V that is standard for the A-series (see the data sheet) but otherwise no problems. Oh, and of course the 1000A isn't full-range output, but as subwoofer-amps they should be great 🙂
Check the data sheet to confirm, but something like 150-200mA for the positive rail and slightly less for the negative IIRC.
