I'm in the middle of a basement remodel and am going to hardwire all speakers. Wire will be ran through the ceiling and will have minimal to no ability to change in future. Was looking at some of the knuconceptz's products. My max run will be no longer than 30ft.

Planned setup is as follows:

Yamaha RXA1020 Receiver
3 Definitive Technology DI5.5LCR in front wall
2 Definitive Technology DI8R in rear ceiling
SVS PB-1000 Sub

What is rule of thumb in terms of planning ahead?
- Do I go with 10 or 12 gauge just to be safe?
- Is anything above 14 gauge for what I am installing ridiculous?
- Recommendations for what type of connectors to use?
- Recommendations on what wiring to use for the sub?

Thanks in advance to all

12 gauge is most likely overkill, 10 gauge is certainly overkill, but there will certainly be no harm (except perhaps to your pocketbook) if you choose to go with either of those. I suppose that depending on your speakers and how you connect them, really heavy gauge wire might make it difficult to physically make connections (for instance, if the wire is so thick it won't feed through the holes in your binding posts). 14 gauge will work fine for runs up to 30 feet, and I can't see you running into any issues with the physical size of it.

Connectors are a matter of personal preference. You probably won't be able to get a better signal path than you can with bare wire tightly twisted and screwed down, but if you install banana or spade lugs correctly you probably won't degrade the signal path much if at all.

Sub wiring (assuming an active subwoofer) will generally consist of RCA-terminated 75 ohm coax. This is commonly called 'subwoofer cable' or 'digital audio cable'. A yellow composite video cable will do in a pinch, too.

I have 50' runs of Monoprice 12ga. in-wall wire for my rear speakers. You should have no problem with 12ga. for your runs. For your shorter runs, 14ga. would be fine, but there's no reason not to use 12ga. if you've got enough of it on a spool.

I wouldn't say ridiculous, but probably overkill. If you want 12ga, that's cool, it can just be a little harder to work with in tight spaces. 14ga will be fine, just make sure it's in-wall rated (CL2 or whatever). Something like this should take care of you:

I went with banana plugs. They're convenient to the extent that you're moving plugs around more than once every couple years.

I don't use connectors on speaker cables in my home. I do on my pro-sound gear since I have to plug and unplug them every time I use them.
