Default using RG6 as co-ax

i have done this before to pretty good results, i am wondering if there are any downsides to using tv cable and soldering RCA jacks on the end, then using them as the sound cables from the head unit to the amps.

i ask because this RG6 is super cheap and i need to run them outside the vehicle.

does it matter RG6, RG8, RG58 etc? i am not using it as a conduit anymore and i am wondering if the rated impedence will make any difference in my application.

It will work. For most applications, speaker wire will work.

One problem you may have is getting a good connection to the shield braid. It's generally aluminum and won't accept solder easily.

Cross sectional area between sheild and center conductor will be a magnet for inducing noise in a car where current is constantly flowing@ground and power points in a car. keep it simple use twisted pair interconnects. Just my $.02!

Use RG-59. Its got a copper braided shield & slightly smaller in diameter than the 56. But do not use co-ax under any circumstances for a speaker wire.

Belden 1694A is a high grade RG-6 studio cable that Blue Jeans Cable sells for RCA interconnects.
I has very good reviews.
