Bad idea?

Many good choices here, Cullen, Pine Tree.   You might also check out Ice Age Audio up in Traverse City, MI

My next purchase will be @daledeee1's suggestion ... full set-up for $110  ...

Don’t cut and terminate yourself unless you are experienced.  Rather, audition the following WyWires model:

Read the following Absolute Sound review below:

$299/4′ pr. interconnect (RCA or XLR); $449/8′ pr. speaker 
The first WyWires cable reviewed in TAS, the Blue is also one of the most pliable, easy-to-handle cables around. Its sonic signature is energetic, with a potent midrange, plenty of drive, and a slightly cooler, forward tilt.

In 99.9% of systems, the person would be better off by saving that money toward a speaker upgrade. 
 

Otherwise, just get a couple 4’ lengths of the 12-gauge Duelund cable from Parts Connexion. It’s all anyone needs. 

Why in the world would you spend $1,000 on speaker cables. Serious question. I assume it's because you want them to look really nice; some eye candy in your system. Because it can't be because you think they'll actually sound any better than using a coat hanger. They won't. Shame on anyone here who says (lies) to the contrary.

The reason that you would spend $1k on speaker cables is the reason I spent $5K on speaker cables. Because the incremental increase in sound quality of the system is worth the expenditure. So the cables increases the sound quality more than the equivalent investment in any other component of the system.
