Can u make interconnect from speaker cables

No, no you can't do that. Previous posts are spot on and good advice.

It would probably be a lot of work. Some IC makers do not use a shield but they often braid the hot and ground to help cope with no real shield. Another challenge would be adapting the much heavier gauge in a speaker cable to fit in your connectors. No reason that I have experienced to keep the larger gauge and the extra capacitance from the larger gauge can be a problem. However if you do not have IC's that are not silver wire based you may want to explore it a bit further.

It is very rare, but I've seen some companies using a coaxial cable, which is suitable for interconnects because of its inherent shielding capabilities, for a speaker cable design.

I have not seen anybody using larger gauge cables (usually used in speaker cables) for an interconnect design. It is generally not recommended to use speaker cable for interconnect and vice-versa.

You can contact CRL and ask them if that particular cable design can be used for an interconnect cable. I will be very surprised if CRL says yes to this question.

These are two interesting articles on audio cables:

You can sell the CRL Silver speaker cable and try many..many interconnects...
