I installed some polk momo's and and cannot get them to stop whining. I know its just amplifing the the alternator, but i dont know what else to do except turn the gain down which i dont want to do? Any ideas?
Its already been done again by a professional, not just the grounds EVERYTHING. Im clueless? Could it be the alternator(possibly needing a new one?)
Anyone think this will work? http://sonicelectronix.com/item_8179...SM+201XLN.html
I have JL RCA's and its not a best buy installation, he knows what hes doing, he completly isolated everything even remote wire. So you don't want ground loop isolaters? I dont know what FTL means.

Ground the shield of your rcas to the case of the head unit.
[psychic power] You have a pioneer headunit.... do what was said above, ground the RCAs. [/psychic power]
WHY THE HELL DOES PIONEER INSIST ON BALANCED RCA OUTPUTS? I replaced 3 headunits when i was young and didnt know better.
Yeah i have an AVIC-D3. Might sound stupid but how do i ground to head unit?
Also might want to mention to your installer to unplug power before unplugging/plugging in RCAs.

system in the works:
Pioneer DEH-940MP, RF T8002 on Peerless XLS 8" midbasses, RF T8004 on DLS Iridium 3" midrange and tweeter, RF T40001 on 2 Adire Brahma 12s, RF 360.2º processor
Use a ring terminal on the rear support hole.Originally Posted by siver701
Grounded to head unit and still getting the whine any other ideas? Thanks guys
I know with the pioneer 800prs there was a micro fuse problem that was causing whine on a good amount of vehicles, don't know if the avic-d3 has the same type of micro fuse, but if it does maybe you blew that fuse.

You will just have to start narrowing it down
Yeh thats what the installer said too, its a brand new amp but i seems that the noise is only coming from the left speaker.
