Whats up AF, i run into another problem, this time with my Pioneer HU im getting a hissing/whine & a minor popping noise with the car on or off. i've checked the basic stuff (wiring,ect), i even checked the rca's with my ipod and i get no hissing noise what so eva. i need your help AF, should i ground my HU rca's to the HU itself or ground the rca's to the car chassis or send it to the shop?

try grounding the rca shield on the hu, to the bolt in the center-back of the deck. try it in a different car. if the same problem exists, send it in for repair...with a detailed note explaining all the steps already taken to be sure it's in the unit

ok thanks for the responds, ima still need more input on this since this is my first time tryin this, pics if possible. do i ground the rca's coming out the HU or the main rca's going to the amp? I understand most of the help just need a lil more.

i "DID" sell pioneer but only for the older people that want a cheap headunit with no amp. pioneer did a STUPID and fused the ground. so when it pops it searches for a ground and the best one is ur rca's.
PIONEER headunit = GARBAGE
i am sorry i dont like to bash any brand but i have had countless problems over the yrs with this and they havent fixed it...

another good hint to help prevent this, always plug your RCA's in last when installing an amplifier. that way the amp doesn't try to ground through the rca's and blow the picofuses in the deck

thanks guys for the help, but ive been using pioneer for years now and IMO, i think if you know how to fix it, it's not to big of a problem..i think i made my mistake hot swapping..thats why they want you to go to a professional pioneer installer.

by fix it, do you mean tearing the deck completely apart, and soldering resistors in where the picofuses were?

i fixed it kind of like the picture at top^^, i bought two 16g wire with fuse holders 10amp fuse, (to be safe), grounded them to the back of the HU & to the rca's, each wire has its own screw in back of the unit..by the way all my feedback, hiss and whine is 98% gone with the car started and off.

multiple amps, same thing. always hook up ground and power before you plug in the rca's. mostly seems to be a problem when using pioneer decks.
