Alex K Posted July 2, 2010 Report Share Posted July 2, 2010 (edited) It's a problem with my rcas, because when I dissconnect them, it stops. Whenever I plug them in the speakers make a popish noise, and then there's this high pitch increasing sound that sounds like they're about to explode. I've checked and rechecked my grounds, im next to a power wire, but it's like for about 2 inches. The rcas are run under the carpet, and most of the wire is hidden under the back seat, just a smidgen is out and that's what runs to my amp. The rcas are y split from another amps line out. It doesn't get louder as the volume or gas pedal is pushed, and you can't even notice it when the musics playing. I've noticed the amp gets a lot hotter then the one running my tweeters. I don't know if this is because it's pushing 2x the power or maybe it's the amp. So a little help here please Edited July 2, 2010 by Alex K Quote 2006 Nissan Z Track.

Beanz Posted July 2, 2010 Report Share Posted July 2, 2010 Maybe a bad ground??? Quote That's why they don't deliver. Yer ass better go sit along the side of the road and wait. You can't expect them to travel up some dirt road in a hick / back woods town. Thats how horror movies start I explain things very simply and use analogies in terms of Pickles, and grape drink, pool noodles and jackhammers...if you can't put 2 and 2 together there man, There simply is not much more I can do.

Alex K Posted July 2, 2010 Author Report Share Posted July 2, 2010 (edited) Not the ground - i've checked several times and it's grounded to the same spot as my AQ1200. Like i said, I think it's my rcas. the sound stops if i remove them. Edited July 2, 2010 by Alex K Quote 2006 Nissan Z Track.

Alex K Posted July 2, 2010 Author Report Share Posted July 2, 2010 I can try a different ground tomorrow - but I HIGHLY doubt that'll fix it. Not gonna lie though, they get loud as fawkkkk now!

J-Lane Posted July 2, 2010 Report Share Posted July 2, 2010 Before ripping out all the RCA's and replacing them. See if you have a set of RCA's and run them from the deck to the amp and see if the problem still exists. How is the head unit grounded? I know that sometimes if you use the factory head unit ground it is usually insufficient. You should try to ground it to the frame as well. It sounds like a ground loop issue the way you are describing the sound. Good luck and let us know what you find. Quote Link to comment Share on other sites More sharing options...
Alex K Posted July 2, 2010 Author Report Share Posted July 2, 2010 Never messed with the HU so it's not that. I'm going to try a different ground tomorrow and see if that fixes it. I'm also going to move the rcas around and see if maybe they're picking up something from the chassis. I have about 20 feet of it wrapped around under my back seat, on the sheet metal (easy hide). I doubt thats it either. The high pitch noise stops when i dissconnect the rcas, so that's where the problem exists. Quote 2006 Nissan Z Track.

J-Lane Posted July 2, 2010 Report Share Posted July 2, 2010 Never messed with the HU so it's not that. Are you running all your equipment off your factory head unit? If you are, I would guess that you are using a high to line level converter. I would check that as well to verify there are no loose wires (some of them can create alot of noise too). I think you might be right though as for the RCA's being the issue. I broke one of my RCA's years ago by pulling too hard and I broke the wires internally. I didn't realize it till I tested everything and I had this weird feedback/whining kind of noise. Quote Link to comment Share on other sites More sharing options...
