Kyblack76 Posted February 18, 2013 Report Share Posted February 18, 2013 im glad i work for direct tv and have more or less unlimited access to coax cable rg6 i will just have to get the rca ends Hook a fellow basshead up!!! I need a bunch of RCA cables lol. i am going to get with Kyle tonight and get a coupon code up for the RCA's. Ill have it up by tonight. Should save a few bucks and i PROMISE you will love the product Im in...

zayres29 Posted February 18, 2013 Report Share Posted February 18, 2013 Steve why are you trying to make things so damn easy i can get 1000ft single and 500ft dual all is rg6 premium 100% shielded and 60% braid im pretty sure its 80ohm swept tested from 5hz to 3000mhz Quote Btw that was the first person.

Pro7 Posted February 18, 2013 Report Share Posted February 18, 2013 TD, Is there some BALANCED and UNBALANCED verbage going on there? yeah the whole inverted signal compared to grounded negative of the rca is the difference in balanced and unbalanced. I had to study up on that when I got my rf-bld and I absolutely love that feature! Thank you Tony for giving me a more visual idea of the two ideas Quote I've gotten a blowjob and picked up my iphone behind her back to see what email notification I got from smd before Link to comment Share on other sites More sharing options...
AMI CUSTOMS Posted February 18, 2013 Report Share Posted February 18, 2013 What his video explains is with a twisted pair RCA, which is what basically everyone sells like crazy, it is noise in = noise out, so noise becomes rejected in the amp, if it is a differential amp, only most high end amps have this feature because you required a differential op amp to sum and reject the noise. Most amps fall into the single input signal format, just signal and ground, no summing or rejecting, so any noise in the system you amplify making it a benefit to use sheilded RCA cables, not twisted pair. Sheilded block noise, twisted allow noise because the amp rejects it if differential based. Like Tony says in the video you will have continuity thru the ground sheild of the RCA on the amp to chassis ground with a DMM, if that is present you need single input Sheilded RCAs. COAX.

zayres29 Posted February 18, 2013 Report Share Posted February 18, 2013 another thing aobut single ended cable is that you cant make sharp bends with it you cant cram it in places and kink it doing that distorts the signal gradual bends are fine as long as it doesnt change the shape of the cable just something i learned working for directv Quote Btw that was the first person.

LordArcane Posted February 18, 2013 Report Share Posted February 18, 2013 (edited) Well just tested my sub amp and no continuity between the main amp ground and the inside pole or outside shield on the amp so guess i been running the right one (twisted). lol little confused but think i got the just of it Edit: power off on car, all rca's unplugged from amp, - lead from dim to ground block, + lead tested both inside pole and out side ring on input rca's on amp, dimm set to continuity.

BBAnonymous Posted February 18, 2013 Report Share Posted February 18, 2013 Thank you for this information, I did not know this and like to learn new things like this, and thanks to Steve for sharing a link on facebook otherwise I may have missed this one. 1 Quote Link to comment Share on other sites More sharing options...
Wicks Posted February 19, 2013 Report Share Posted February 19, 2013 Awesome vid Tony! 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. 2 Quote This post sent with 100% recycled electrons. 2004 BMW M3Mechman 280A 2 - XS Power XP30001 - XS Power D375 500F of Maxwell SuperCaps (soon to be 1000F) iPadMini2Dash mounted O-scopeAudison bitOne (Remote DRC MP) Highs Amp - PPI Art A404 Hertz HSK130 (HSK165 waiting...)

KMS Posted February 19, 2013 Report Share Posted February 19, 2013 great video! FYI: http://www.wccaraudio.com if you need high quality RCA's ....just wanted to share that info $50 to $60 for 3 feet. No thanks, I'll keep using what has been working just fine. 1 Quote Alpine PDX-V9 Morel Tempo 6 Alpine SBR-S8-4 Alpine CDE 149BT Link to comment Share on other sites More sharing options...
