Quick question for you all. I tried a search but didn't find what I need. I have a Kenwood in dash DVD player connected to a Kicker CVR 12" The set up and wiring was working completely fine, but after a week I started getting horrible feedback from the sub. My friend had installed the headunit, so I went back and traced the wires. He had the RCA, remote, and power wires running together. So I seaperated the RCA's from the remote wire and I still have feedback. I checked the amp ground. moved it around a little. Now I have a humming feedback, and it gets higer pitched when I hit the gas. i'm not quite sure what to check from here, so any advice would be appreciated!

Ok, first your wires are run wrong. The POWER and RCA CANNOT be ran on the same side of the car. You have to separate those two and makes sure they never cross, and i would run the remote wire with the power not RCA's, but i do not believe it will make a difference. Also, I do not know exactly where the fuel pump on our cars are, but if you run wires over that if will give you feedback as well. If that does not work than your blew a circuit in your deck. If problem persists repost and i'll tell you what to do to check your deck's circuits. Hope this works

Dude thats all BS. you dont have to seprate, it dosnt make a fly bit of a dif. People say you do, i have done and i havnt, my car right now are both togeather one on top of the other and go right on top of the fuel pump and they work perfect.

Please do not give any false indo.Scarlle is most likly right. You could also try a ground fault interupter. I had to use one in my old dodge cause i couldnt find out what was causeing feedback and it worked perfect.

Definitely not BS. Ever work with stereo's before? I have put in well over 30 systems before and helped fix many people with this exact problem. Maybe if you only have 8 gauge power wire and cruddy RCA's then it won't matter. If your running anything higher than 4 gauge wire and your amps runs higher than around 800 watts it most likely will cause problems, test it yourself. If they are ran on the same side w/no problems you may have very little feedback you can't hear, which is not good for your subs either. As far as the fuel pump problem goes, thats is also true. My friend has a competition stereo that was putting out weird feedback and we didnt know why, turned out the wires ran over the fuel pump. This was told to me that it may cause problems by MANY different audio stores. And the bad ground is a very good idea that might be correct. I was just trying to help out through my past experiences. And it would be appreciated if you do not give any false info.

Yes I have worked sold and installed stereos before. It does not make a dif.

Also you should might wanna mention why it might. Its the fact of useing both cheap power and rca cables. If you use proper shealed wires then you'll be fine. Not all rcas are shielded then you might get feedback, which is caused from freq cross from the main power. I have also prolly installed over 40 steros and help with over 100 from when i worked at bestbuy.

Next time you want to make a coment that is not 100% true. back it up with reason. wink.gif

Its not a greta idea to runt hem togeather, but if you have the right wires, which you should. It will be 100% fine.

EDIT: ALso Im running 4 gauge with a 900 watt RMS amp. It works perfect wink.gif

True on most parts, but even if you have good wires you still might get that feedback. I have worked with good wires and still had a problem. I have a competition stereo i did all myself and i had very little feedback. My power crossed the RCA's once without even touching, couldnt get around it because of the way my setup is, i had to re-run them and many other things and problem was solved. And i have good wires, Monster Competition RCA's and Tsunami zero gauge mad.gif

And you contradicted yourself, so make sure your comments are 100% true as well.

When it domes down to it, every car and setup are different and all have different problems and reasons for them, unfortunately things are not as simple as we all wish they were. frown.gif

And judging with your setup i would assume you probably have some kind of feedback so low you never hear it, if you dont then IDK, like i said every setup is different. confused.gif

And guess i just felt that saying they should be separated was enough info. Afterall people are looking for help because they may not have enough experience with stereos, don't want to confuse them with giving too much info. like frequency cross from the main power. Most people just wanna know how to fix the problem. Next time i'll include reason. smile.gif
