I am looking to run a 25ft-35ft audio cable to my subwoofer (PSW505) I am just concerned about running a cable of this length with losing signal strength.

I was wondering if this is going to be the case the cable will be bought from monoprice see link below...

You should be fine, it's using RG6 not RG59 so the signal won't degrade as quick.

Yup what he said. You are good with runs that length. I have used many monoprice cables and have had good luck with them. Don't sweat it!

I've been taught by the forum (and checked this out elsewhere) that for baseband audio signals (subwoofers, analog audio / RCA), RG59 is actually better than RG6. At least when we're talking about normal off-the-shelf cable. The difference is in the shielding / insulation, which is different between the two cable types. The typical construction of RG59 has better characteristics for low-frequency signals, while RG6 works better for high-frequencies (and is why it's required for high-bandwidth satellite and CATV).

The "best" thing to use are the RG6-grade wire made specifically for audio (or baseband video, not CATV), like the Belden Precision 1694a.

Now, that said, for short runs I don't think it will make any difference either way, and if there's a chance the wire will be used for other purposes, I'd probably stick with RG6.

Audio can run long distances without any loss in signal. In fact since it is powered Subwoofer, if there is any loss, you can adjust it with the amplifier on the Subwoofer anyways.

I would not worry about it.

A major cable manufacture may have more than 40 different RG-59 part numbers and can also have more than 40 different RG-6 part numbers. This part numbers will differ in fire safety, weather resistance, flexibility, strength and the optimized frequency band.
In any case for long unbalanced analog interconnects the most important parameter is low end to end resistance of the shield/return.
