Rel sub

Also, I run only a single signal wire out, hot to positive on amps, ground to chassis. With two signal wires, to both positive and negative binding posts I get excessive output, read about this in owners manual and/or forums. And, I run a set of diy cables to the REL's, I use only Neutrik brand, no fakes, and just enough length of Duelund tin plated copper, far superior to the stock cable in any length. The cabling does affect sound quality of REL subs. I'm next going to experiment with VHAudio AirLock, OCC copper/ solid core wire, this vs the Litz wire in stock and Duelund cables. Some claim solid core more impactful, articulate than Litz.

I meant to say Neutrik CONNECTORS, there are inferior fakes out there.

@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
