I'm building a 7.1.2 cinema room and the cables will be run through the wall and ceiling. Are these cables ok to use? Trying to keep the cost as low as I can without sacrificing quality.

Wall and atmos cable: Amazon product
Powered dropdown screen: Amazon product
Sub: Amazon product

Rather than generic RG6 why not just buy pre terminated sub or RCA cables. Far easier and better connections. I just used a 15m Amazon one and it’s fine.

Thanks - would you have a link please?

I don't see the Amazon links on this end so I can't comment on the cables.

How long is your cable run and are you going to use conduit (you should as that is the ONLY way to future proof your cable installation)?

That's strange, not sure why the links won't work.

Run is about 5m.. cables would be in a bulkhead so think I should be ok on the future proof front

5m (15') is within the range for passive, certified, Premium High Speed HDMI cables (HDMI 2.0, 18Gbps) so if you want to push 4k HDR you should be fine. If you are considering the HDMI 2.1 options sets down the road, and your cable run is under 15' (9' ideally), then you may be able to upgrade your cabling to the certified Ultra High Speed HDMI cables (HDMI 2.1, 48Gbps) eventually. But you need to keep in mind bend radius and no wall plates, adapters, extenders, etc in-between. A single cable run source to sink is recommended. Links still don't work for me so I can see which HDMI cables you are looking at.

None of the links are fit hdmi cables. They're all speaker related. Let me see if I can post them again

The links still don't appear here. However, if they are not for HDMI cables then someone else should answer your questions. It sounds like @mushii already did that.

2x2.5mm speaker cable is usually recommended for most systems so a 2x1.5mm cable looks a little thin.

Agree with mushii that pulling a pre terminated RCA>RCA cable is more practical unless you are good with a soldering iron - and remember the Sub requires a local mains socket too.

Thanks Joe. What would be the issue with 1.5mm cable?

Do you have any links to 2.5mm cable which you would recommend?

You don't want the gauge of cable being an issue when you have long cables/try to push power over the cables - 2x1.5mm is usually fine for lower power systems with short cable runs, we settled on installing 2x2.5mm on pretty much all systems many years ago.

We usually supply and recommend either VanDamme Blue Series or more recently our TMF Black Series 2x2.5mm cable - TMF Black Series Loudspeaker Cable 2x2.5mm - The Media Factory

I agree with Joe you would be better served with 2.5mm diameter cable. Van Damme Blue is a good recommendation if you can accommodate the size and bend radius of it: it's very well insulated which results in a larger physical space requirement and bigger bend radius.

The better cable retailers will cut to your specification and terminate with plugs of your choosing. I have this, and am perfectly happy with it: 2.5mm speaker cable cut and terminated to order

For Sub cabling, I suggest just buying an off-the-shelf RCA cable of the right length and grade for your needs. Sub cables are often seen at massive discounts, so don't be suckered into spending silly money!
