I am hooking up my sub via speaker inputs and need a place to attach a ground. I don’t see any obvious places on the back except for two screws near the sd card slot. Any one know where I could attach a cable to ground on the p 10?

Either of the screws next to the SD card slot would work for grounding your sub if needed.

Why would you require a ground when using the high level outputs of the amp to drive the sub woofer. I have never hear of that. Be careful of unnecessary grounds as you can cause a ground loop that will cause hum or worse!

If the amp in questions is Class D you have to connect the negative cable from the amps to the sub to an alternative grounding point and not the negative binding post.

What subwoofer are you using? Rel has been recommending grounding through an RCA cable recently and it seems to work quite well. You can take a look here for more info.

What other gear do you have in the setup? Do you have a phono ground?

No unfortunately I do not. I have a wyred 4 sound ST 500 amp the p P10 and a DSD dac. The sub is Rythmik f12 se.

O.K. with the Rythmik you can’t use the REL method with the RCA cable as a ground. If your speaker cables have spades then try the screw just under the binding posts. One for each side. If that doesn’t work let me know.

Please check with Wyred 4 Sound before attempting this connection. I would hate to see you kill the amp. I have an ST 1000 mk 2 and I know it is basically a bridged output two hot terminals no ground.

That’s why you use an alternative ground method for the sub only. As long as the main speakers are connected normally no harm will come to the amp. I have used this method with four different Class D amps including two IcePower based amps including mAmps.

I am considering getting a couple REL subs to use with my Bel Canto REF600M monos. But all this “must have correct connection” warnings are discouraging. If anyone is currently using the 600Ms with speaker high level out to the sub, I would like to know how it is working out for you. Did you have…

Is there a place on the back of P 10 to attach ground cable?
