It gets worse

Sweet! Now I can sync them with these babies

$150?? get on my level.

Man. That's cheap wait till you get a sweet sound system and need a cable.

In short, not really. As long as it makes a connection and doesn't provide too much resistance, it will be fine and you probably won't notice a difference.

The quality of cable CAN make a difference though, mostly over long distances where electrical resistance (impedance) and amperage are a consideration. Impedance can affect how hard your amplifier has to work to deliver the audio signal. The gauge and type of cable is going to be the biggest factor in this regard.

The cable should be a good conductor of electricity. Pure silver has one of the best coefficients of conductivity, but it is expensive. Copper is a cheaper alternative that is still very conductive, that is why it is such a popular choice for all types of wiring. Gold is less conductive than copper, and aluminum is less conductive than gold, etc...

Another factor in reducing impedence would be the gauge, or size of the cable. Thicker cables allow more electrical current (amperage) to flow through, and thereby have less impedance.
An 18GA wire can handle less current than a 12GA wire. A 12 GA wire will have more resistance than a 10GA wire.

Impedence increases over distance, so longer runs of speaker cable may require thicker gauge cables, and/or more conductive materials to deliver the signal from the amp to the speakers as efficiently as a short cable.

Here's a handy-dandy calculator to help you determine the proper cable.

And here's a chart for determining the max length of cable / system impedence-load, in case you don't feel like looking up
the picofarads of a particular brand of cable. or dampening factor of your amp.

The type of wire has a smaller effect on the performance of a cable than any of the aforementioned factors, but should still be considered. Because of the skin effect high frequency electrons travel along the outside edge of a strand of wire. It is for this reason that stranded wire is preferable.

tl;dr
I would recommend taking out a second mortgage and getting something like this just to be sure you get the best audio quality. /s

It is ridiculous, but I think [this] (https://www.amazon.com/WIREWORLD-Platinum-Eclipse-Speaker-Cable/dp/B00CHSRKJW/ref=sr_1_2?ie=UTF8&qid=1519881234&sr=8-2&keywords=wire) is just a crime against audiophilia

What about this?

Awesome, get another couple and you're good to go! While you're at it go for one of these if you can https://www.amazon.com/dp/B00CHSRKJW/ref=psdc_3236443011_t2_B00KY2NKCO

You should upgrade the speaker cables:
