Truth about RCA cables. Coax vs Twisted Pair


Recommended Posts

DAmoreEngineering 26 minutes ago

If the head unit has SE outputs and the amplifier has SE inputs = coax cable

If the head unit has SE outputs and the amplifier has Diff inputs = twisted pair

If the head unit has Diff outputs and the amplifier has Diff inputs = twister pair

If the head unit has Diff outputs and the amplifier has SE inputs = bad no matter what as you will shorting out half of the head unit's outputs. In this case you would need an amplifier with Diff inputs or a converter to convert the head unit's outputs to SE

I don't put images in my signature to let people know I mean business.

great video!

FYI: http://www.wccaraudio.com if you need high quality RCA's ....just wanted to share that info :D

$50 to $60 for 3 feet. No thanks, I'll keep using what has been working just fine.

As much as your post contributes, ill post one that is just as lacking.

Then dont buy em.... And head back to radio shack........

Me,.. im ordering on Friday.

Awesome vid Tony! :good:

I just received my custom 20' SMD COAX cables and love them.

I haven't had a chance to install them yet, but I do have some very detailed measurements comparing them to the regular RG6 coax that I was using.

Resistance-wise the SMD COAX cables are better then RG6 which is impressive since RG6 has a very thick center conductor.

RG6 has less capacitance (better) then the SMD's, most likely due to the increased diameter it has. This is a very minimal difference though and the MUCH better flexibility of the SMD cable far outweighs the RG6 in my opinion.

The RG6 had about twice the inductance of the SMD cables which adds up to more inductive reactance in the upper frequencies.

All measurements were swept from 20Hz to 20kHz.

I've used two different types of RG6 COAX before and to me, these SMD COAX cables are much better.

They are MUCH more flexible and very well made.

I'll post more details after I install mine and do some more measurements.

For anybody interested or new to these cables:

Make sure you also check your HU for its output as well.

To make the best use of each cable type, you'd want to match the HU output to the amplifier input along with the correct cable type.

awesome! Glad you like them so far :)
