Green eyed devil's In Car Entertainment System Upgrade

[roms]

maddy bhai, what was the cause and how that happened and how we can avoid this kind of situation. plz explain briefly

[madhouse12]

fault: ground wires became weak

reason: salt developed in wires due to moisture because local wires are not pure copper

Remedy: changed wires back to stock for now

to avoid future mishaps: get pure copper wires and insulate them against elements as much as possible

Arslan Bhai let me say few words

,it's an unfortunate event that occurred to ur wires ..If u weren't in ur city or was on the move this kind of mishaps can prove to be a serious struggle for one and can cause huge time being wasted

Sir in doing big 3 wire upgrade it is advised To keep ur stock wires as it is in their places because removing them does not really matter ...new wires are to run along them ..

Got local copper wires for my big 3 ,,and my recent vist to bilal gunj I got 2 gauge insulted rubber wire for my amplifier (not yet installed). At about 149rs /feet..

Cause here in bilal gunj there is whole wire market with a lot of variety from local to imported insulated wires ... Pure copper available .. U can check it by cutting it from middle or and scratching it off with a knife.. Silver comes out ...

[madhouse12]

Some people advice to remove the stock wiring. And it was not possible for me to run em as i needed to put in a new battery terminal.

[madhouse12]

As for pure copper and scratching em too see if they are cladding wires, u can look at the end of wires. If they are cladding, u will see silver. Unfortunately the wires i have are copper but of low quality. Scratching em does not reveal anything

[Talhadon]

One thing i didn't know till now.....!!

Is pure copper will be very hard or very soft??

Some say the more the soft copper the pure copper it is...............Some say the more the hard copper the pure copper it is....:S

How can we identify it is pure copper??
Need guidance regarding it!

[madhouse12]

pure copper is a soft metal. In wire form it depends on the size of individual strand of wire. Household wire strands are thick so they are hard to bend. Audio gauge wires have thin strands so they are more flexible

I need 3m of 4guage wire for my second amp, any ideas guys?

moonjee checked with bobby, and he is quite rfankly a rip off

hmm i see it to.... difficult to put in with your stock wires as u were using two wires as one instead of one single wire for big three..the thing i suppose pull out stock wires because that are genuine wires must be pure cooper .. you can never doubt them.

agreed....

best method desi dukan walas use is to cut the wire from center and see if silver shine comes out the core..

yes sir there are different composition for copper in wire ..one is never in world 100 % pure .. more %age copper better conduction.. one i got is more than 80%+ copper as per shopkeeper though there were more copper one but to at higher rate:rolleyes:

divergent myths of different people

though when back in grade 8 i studied that copper is soft metal.. need composition of others to maker it hard to pull out as wires

hold your horses dude lolz at bobby:P

he is mad with rates these days ... asked the price ov two things

1. soundstream refernce (ur model)= 24500/-

2.kicker solox 18" = 1,60,000/-

sahi khaal utarae ga bhai

and bro do ask hamza bilal ... he told me about his bad experience of fusion wires from bobby which turned out be copper coated silver

check at bilal gunj ...u will get gud copper wires at pocket friendly rate,
,
whole wire market there but khawarii bohut hai:P

let me post sum wire pixs

[blacklist1]

17 feet (aprox 5.2 meters)

aprox 2 gauge

at aprox 300/- per foot

The thing is, the copper wire has to be "oxygen free" (OFC = Oxygen free copper)
[I]
Many cables today are advertised as using "oxygen-free copper," copper which has been annealed in an oxygen-free atmosphere. OFC is popular in audio cables, and has begun to make inroads into the video cable market as well.

We all know, of course, that oxygen is bad for things made from copper. Copper oxidizes and turns green and flaky; in so doing, it loses its high conductivity and begins to fall apart. But the amount of oxygen present in conventionally annealed, non-OFC copper is so tiny that it simply isn't a factor in cable quality. We have cut into pieces of Belden coaxial cable 25-years old that have been used in radio transmission applications and found them clean and bright, completely lacking any sign of oxidation. Modern coax is better still, with nitrogen-injected foam dielectrics that keep oxygen entirely away from the center conductor.[/I] [I]

As it is with silver, there's nothing wrong with OFC; but electrically speaking, OFC wire is indistinguishable in audio and video applications from ordinary annealed copper wire[/I] .

[moonjee]

Bad I got 25 meter's of OEHLBACH from him, it was highly priced but then I had no other option Besides the stuff was good so I went for it..

Regarding power wire, I have something very rare for you Its, two core, 8awg each, telecom grade DC cable that works for 48V DC, not 12V DC This can work as a 4awg if both cores are joined, since its silver therefore no oxidation What do you say? I have 9 meters of it.. How much do you want? Its made in Sweden The home of telecommunication..

Chao!

[madhouse12]

being an educated lohaar myself (metallurgist) and the recent experience that i had, i would say it is better to get OFC wires. we have to remember that our local wires are prepared at much lower standards then the international. what they prepare as normal wires, manufacturers here might call OFC here. infact i have seen clad wires with OFC copper written on em. addition of oxygen in copper makes it hard.

anyways conductivity in metals is Gold>Silver>Copper>aluminum
so if some shopkeeper says its copper coated silver, he doesnt know jack about wires cos first of all silver is too expensive to be used in wires. secondly it is a better conductor so u wont coat it with copper. the "SILVER" is actually aluminum because it is cheaper than copper and has lesser density than copper so it means u get more volume per kg than copper.

i sliced my faulty cable open and took some pics of it. uploaded em on FB but sinceFB is blocked in office, i can post em here right now. so if shahid bhai or yawar or any other guy can copy them here, you will see what becomes of a cable when it oxidizes.

Ahaan that's the case:S .. Never wondered why street wires and many others

Advertised their wires to be oxygen free ..l

OFC s are good to have for car audio to lessen the probability of cladding ..

Nice share ....

Yo ... Oehlbach is best here ... I was taking in account his prices and the thing that. Happened to hamza bilal

Agree with you sir

Ha the Local ofc s can't compare to that of international standards

Locals term aluminium as silver here , they don't know that s it's better conductor ...

Of one wires I saw a imported copper wire coated with silver to be remedy for oxidation ..but than I only knew Kay bas copper he laine hai:P

But ultimately if your pocket is tight and here in Pakistan non ofc s ,normal annealed copper wires are the ones in your kismat;)

Btw maddy bro how u see my wire gud for amplifier (magus )?....Good for its bucks ?:S

[madhouse12]

even the wire u say u saw were coated with silver are not coated with silver. its actually tin as you can see in faheel's thread. the wire you have is pretty good. i am guessing its welding wire.
