Speakers amp funny whistling sound

hey there.. I recently got a new deck, hooked up my amp etc...

while leaving my speakers on... and sub running, i took off a pair of speaker cables, and tried to get it into the parcel shelf of my car.(to get them to the 6.9's).. doing soo, the wires hit the metal of the car... little "fizz" sound, and my amp turned off.. doodie myself thinking  blew my amp.. turned of the ignition, then turned it back on... amp turned on all sweeet and hooked up the cables... now the problem

when my car is in ACC mode, and the cd player is going, the sound from the speakers/SUB is beautiful, no problems at all.. when i start the ignition and the car is running, the 6.9's in the back(hooked up 2 6.9's and a pioneer 12 inch sub to the 4ch/amp).. the 6.9's make this whistling, wizzing sound... its sort of intune to the reving of the car... when i pressed the accelerator, the whistling rate increases, then wen i let go the whizzing comes back down with the RPM ... i checked my ground... it was ok... i never had this problem, i,m thinking i fkt something in the amp wen i was doing doodie with the amp on...(i,m an idiot, but owell)

does any1 know what it is?

hope ive just mixed 1 or 2 wires up.... but yer, all feedback is great

yesss sound does come from my 6.9's! when its low i can hear the whizzing, when i pump it, u cant....

my rca's are running down the left side of my car... and the power cables down the right side (holden calais VR 93)

as for the rcas there not the best onez, but they do the job... i never had this problem with my old deck..... got the pioneer 3850mp, whats this ground loop thing man.... ummz, i got my cd player grounded to the stock wire... i cut of that little clip thing and attached the wire to the stock ground... as the the amp.... i sanded down a part of the inside of the boot, drilled a hole, and drilled in the bit....

it didnt ust to whine like that...

because of new deck?

or because i scrwewed around with the amp, when it was on and the speaker wires hit the body of the car..

and can someone please explain what a ground loop is:)

once again, ive had this system hooked up, with no problem, with my neck deck.... anyway... see what u guys type, thanks for the interest

TJ from down under LOL

sorry i last line,.. i had this system hooked up with my old deck.. and no whining, i put the new deck in.. and its whining.

as for the slip, i,m talking about the clip that runs of the deck, the little U shaped thing. that u screw into the body, is it that maybe?

what the hell r u saying about the amp and the dentist man... lol,

also what i got diff then the other deck, is the the old deck had 4 preouts, with the pioneer (it only has 2 sub/pre outs) i have 2 spiltterS attached to make it four... could it be anything to do with that?

i think i found out what i fkt up on.... will fix when i get time 2 fix it!

CHECK THIS PICTURE OUT... i made it quick, so dont diss the purple sub

ATM its set up like figure 1, but i think it should be like figure 2... would result it way less noise, what u guys think.... i so think thats my problemm..
