Rel sub

@fertguy now that you’ve settled on 2 RELs, when you get the wiring sorted (floating the ground or not and only requiring 1 hot lead per channel) I suggest ordering a custom set of Speakon cables from designacable.com in the UK

They use genuine Neutriik connectors, and cost way less than RELs premium cables.

Frank at Signal Cable also makes some but I haven’t tried them.

Btw I was surprised that REL doesn’t use Neutrik on their stock cables

@fertguy I'm using Duelund tin plated copper wire on REL's, I'd take easy bet on these diy cables being superior to the two you mentioned, read some reviews on the Duelund wire for speakers. For DIY cables you don't even have to know how to solder, with the Neutrik you can clamp without solder, bare wire at both ends. You don't have to spend big money if you diy, and diy can be superior to any pre-assembled REL cable out there. Just like the amp, cables affect sound quality of REL's, part of tuning these subs for coherence with main speakers.

Thanks for the info but I'll more than likely just buy good cables.
