whine noise

• Make sure that none of you RCA wires are running beside your power wires
• check your ground wires and make sure the paint is all scrapped off that area that the ground wire is attached to
• make sure that the gains on the amp are not maxed out. This will give you whining noises
• make sure your ground is less than 3 feet long

hie,

i'm a newbies here......

i'm using a kenwood KEC202  2-Way or 3-Way Electronic Crossover only to  audiovox amp. the 2X 8' sub.

my front are using phase inner 5 1/2 inches and kenwood 1 1/2 tweeter.

my rear only have that 2 8' sub...

i found that no matter what cable i use,it still got the wind noise when i increase engine RPM.....  anyone can help me???

maybe the rem wire i connect wrongly....

i connect the amp rem and kec202 rem together from the pioneer 2450 cd player .....

power supply to kec202 together with the cd player

ground to kec 202 together with the cd player

before i install my 12' earthquake sub.. i hope to settle down this problem....

helps.... information appreciated... thanks

I have a  kenwood kdc x815 or something I've had now for about a year or two.(detachable motorized face,  built in xover, seperate front rear and non fading sub outputs). I can't exactly remember the model. But I had a similar problem with the engine whine. I chose to use an inline ground loop isolator. Not the choice of many professionals, but it worked for me. Fairly cheap brought from any wally mart store for about 12bucks. Just plugs into the rca line output from the head unit and then the output from the isolator plugs into the amp.

thank u so much friend,.... i going to find the isolator and plug according to ur advise.....
