I am new to car audio and researching extensively. I have read that it is critical to seperate power wire from spearker wire and rca cable. (seperate sides of the car floor). So why is it when I look at the amp install pics at cardomain the wires are not kept seperate at the amp? Some have even cable tied power and speaker together in a bundle. Most installs show the wires touching each other at the amp? Are these bad installs? Also behind the head unit I see power wires bundled with speaker wire? Is it critical to seperate power wire behind the head unit?
I run my power wire along with my ground. My speaker wire is run along the same side as the p/g wire but they never meet. My rca's are running down the middle console with the remote turn on wire.while the rest of wiring is under the drivers floor trimpanel /carpet.. That's the proper way to do it, that being said not even the power/ ground wires even touch. As for what's behind the hu, I won't go there, everyone is different and have their own technique.
Here is a thread that you may want to read http://www.the12volt.com/installbay/forum_posts.asp?TID=65069&KW=haemphyst&PN=0&TPN=1
cardomain does not want to show you how to properly install equipment. Cardomain wants to sell you equipment. Please listen to your brethren here and separate the power wires from the rca's. signal carrying wires are highly succeptible to outside interference from other sources (like your vehicles charging system, for example). It takes a couple of extra minutes to route the wires properly, and you will not be sorry for doing so. even if you experience "noise problems", you will be happy that you have one less thing to troubleshoot.
I cant believe I read all 5 pages,Any how forgetting about EMF ,STDs, and DILIGAF. If you can ,separate your wires,keep them as neat and tidy as possible if you do have a noise problem it makes it much easier to troubleshoot.I had an 89 bird with 700 watts soundstream ,always scored 8 out of 8 on wiring and only had noise problems when the car needed a tune-up,
I have not checked out any of the links on wiring, but i dont care too either at this time of night. So i will just say these few things. Run your power wire/remote along one side of the car, and all your audio cables along the other side. The short runs of where they intercept each other generally is not an issue. Keep your power wire away from any factory wiring as best you can due to EMF. Als o do the same with your signal cables, keep them away from factory wiring also for the same reasons. Sometimes this may mean running them down the center of the car along the tranny hump area..... Speake wires and RCA wires can co-exist in the same area without any issues. Even power wires of low current can exist in the same enviorment without problems. But the LONG runs of high current wire next to signal wires can and will cause issues. This is not a 100% guarantee that you will not have noise issues, but it sure helps
I was workin on my friends car...the one with the "professional installation" painted ground....they ran all the cables down the drivers side. But he hasn't had any noise or interference at all...So I ran another set of RCAs down the same side...then the next day he got some minor scratchy interference...I crossed the RCA cable over his 0 gauge near the rear so I crossed it over at a 90 degree angle...fixed the noise...I don't know how this is supposed to work but it does
When wiring is run paralel together, it can inductively couple. allow the magnetic field of one wire to transmit over to the next wire. Same basic idea of how a transformer works. When run at a 90 degree cross over this possibility is greatly eliminated.
Awesome...I tried explaining to my friend that the wires each have a small electromagnetic field and the crossing over at a 90 degree angle cancels that effect out...but now I know Thanks Viking
