HI everyone. just trying to get an idea on rca cables. now i need fairly long ones, and i have some rpm noise whine so im gonna try and buy a couple stes, either second hand or new. what brands are worth their money, maybe a cheaper name but high quality as an expensive kinda pair? i dont want to spend a whole lot. maybe under 40.00 CANADIAN A SET.

 

95Probite,

Look for a cable that has 'twisted pair' and 'shielding'.

The twisting will cancel out most noise that the cable picks up and the shielding will help stop the noise being picked up in the first place.

You will have no problem finding a 5M cable with these build qualities for 40 bucks.

Check out cables from a known brand and you should be OK.

Stinger Hyper Series-39.99 for 17ft (at FS)twisted, sheilded, brand name, look half decent--just a suggestion

 

BUT are you sure the RCA is the source of the whine?

 

JohnVroom is right,

The RCA cant hurt, but it might not fix your problem.

Make sure your grounds are solid and it cant hurt to ground your head-unit to chassis and bypass the ground in the factory harness.

I have seen some harnesses have a continuity to ground of 14 ohms.....should be way below 1.

 

OK THX FOR THE TIPS! but loudtdi, by by-passing the ground do you mean splice a long wire to the HU black wire that comes out of the wire harness for the HU and run it to the chassis of the car? would connecting it to the same ground as my amps do the trick?

or do you mean, not connecting anything at all to that harness black wire then run wire from the BODY , like a screw, to the chassis??

thx!

 

im guessing the ground is the problem also

 

Probite,

The ground from your deck harness ( extended of course) should be grounded to a good chassis ground.....do not attach it to the factory harness.

You should also have the constant power wire for the deck wired seperate as well.....a piece of 12 AWG speaker wire works great or 10 AWG power wire.

The problem with using the factory ground wire is that you have no idea what else might be sharing the same line and introducing noise into it.

 

now the constant power, would that involve the red or yellow wire? i beleive the ACC wire is red on my pioneer deck and BATT. wire is yellow, but i may be mixed up on that, sorry! anyway. which ever wire it is, how do i run it? just stright to my battery with a fuse on it? if so, isnt that dangerous or anything?

and what do i do with the other wire left over? either the red or yellow? thx a lot!
