cardas golden reference sound signature


I have a pair of cardas golden reference and absolutely love the warmish and full body sound.

I have been contemplating putting the cardas sound into my in-car-entertainment but the cost of a 5 meters pair is just too costly.

Would appreciate any suggestion for cheaper alternative cable that would sound similar to the cardas.

Thanks.

I think considering the environment of a car moving down the road and producing road noise that expensive cables would never fully yield their potential. Just my opinion of course.
With that in mind I think buying a bulk cable from AudioQuest or similar would deliver a level of performance to the appreciable capability.
I have to agree. What kind of components would you have in your car that would warrant a cable purchase of even half or quarter the price of the GR?
I have a pretty decent Focal Utopia 3 Ways with Focal Crossblock No 7.

I understand car hifi will never be as good as home hifi but as I travel about 600 miles weekly I am willing to spend at about half the price of the cardas golden reference.
