Motor Noise?

See, I assumed thumper meant noise in the system...if he means mechanical noise...well Hmmm...I'm not really that knows that kind of stuff as well as audio. /NyxBass

Hmm, being that it's posted in Car Audio and most of us refer to motor noise as uhmm motor noise in the system, I'm also assuming he's talking about noise in the system. ;) ...a mechanical noise elsewhere because of a faulty ground, probably not.

Man, I just read my post above...someone should really learn to smack me before I post things like that! And perhaps it's, like a "cutting out" motor noise cause of an intermittent short in the ground....? Alright, I'm reaching here, and I know it. /NyxBass

ok .........a good place to start is with the way you wired you RCA cables and whether or not you ran them next to or (parallel) to the power cable........the power cable sometimes carrys a frequency made by the alternator.........if you have your RCA cables next to your power wire sometimes they will pick the noise up and you will hear it in your speakers........it is as simple to fix as re-routing your RCA cable away from your power wire.......      Hope this takes care of it .................Lee

a bad ground usually causes "alternator whine" where the whine in the speakers is proportional in frequency to the RPM of the engine. rev up the motor, and the whine gets higher in pitch.keep all ground wires as short and close to the component as possible. never run a power wire next to a signal wire (I run power down one side of a car, and signal down the middle, or other side)use noise filters/isolators/chokes to kill feedback and ground loops where neededuse good, shielded cablewatch out for things like power and high current (fuel pump power, etc) lines run under a floor board or carpet you may not initially noticeand so forthkey words: COMMON SENSE. it'ss save ya every time :)-GlassWolf
