I was thinking I could make my own RCA Wires for a tenth of the price of the name brand stuff. Just using RG59 Coax (yep the stuff that goes into your cable box) And just use BNC RCA adapters. has anybody tried this?

 

RG6 but i would only run that for MONO connection, so if its to a SUB amp your all good.....thats what I did in my Home Theater.....do RG6, it passes a cleaner signal, but again, to mono only.

 

You can but take shielding into consideration... My buddy did this to save about 20 dollars and he had a lot of noise....

Just invest in a decent pair... Keep them with the car when/if you sell it...
