Split loom is good if large enough. On a couple systems where the bundle of wires were too large, I used a cardboard "mailer" which is a 2" tube that you might mail a rolled up poster or calendar in. They can be white to match the wall or painted to taste.

Please remember to keep power wires away from signal wires. Even better, power, interconnect, and speaker wires should all be kept away from each other. Car audio installers are usually anal about such distancing.

Yeah the bundles get pretty thick.

I have three sets of loom running up the back. Power on one side and then Interconnects on the other. Coax have separate loom running the same side as the interconnects. Amp is on the bottom of the rack, then tuner and then sky. Don't put things in to those boxes, videos and DVD further up, saves bending down. So Amp being at the bottom allows the speakers to run straight to the wall box and then off through the concrete floor.

The whole room has had serious praise. The 'stack' even got praised by the wife for looking tidy at last. That is praise. It was worth spending the time.

Still may make custom metal cable runs and affix to the rear of the stand although haven't started so don't know if I ever will.
