Very serious noise after amp install

Hey all,

At a loss on how to solve this.

Setup:
2013 Accord LX, stock head unit
PAC Line out converter
Stock door speakers, haven't put the new ones in because of the problems
Brand new JVC 4 channel amp under the seat
Infinity 8" sub in trunk

So, the problem.. Everything plays fine with the car on, for up to a minute. Within that minute, everything hooked up to the amp (2 door speakers, and bridged sub on chan 3&4) go haywire.. They seem to be picking up feedback or something but it isn't a small noise. The sub seems like its working as hard as it can making all kinds of noise, same from the amped door speakers. Its a constant, deep, hum when it starts.

Pressing the accelerator briefly, will briefly stop the noise only to return shortly after.

Another odd one is that if I open the driver door, it stops and won't come back either, and operation seems perfectly fine, all speakers playing, etc.

What I've tried:
Made sure RCAs and power wires aren't together
Tried another power cable all together
Tried a different RCA cable all together
Swapped LOC units, 2 different brands
Changed remote wire (Just jumped it to eliminate possibility of bad connection
Swapped RCA leads going to the amp
Tried 2 different ground connections and also running a straight wire from battery

I'm really at a loss, no idea what it could be. Seems like possibly a faulty amp, but then why if I hit the accelerator or open the door does it function flawlessly? I can't imagine its the speakers causing something like this.

Any and all ideas are welcome. Thanks in advance!

Sounds like it has the ANC mic for the handsfree system. You can just disconnect the module, it's below the radio, or you should be able to get to it by removing the panel on the passenger side of the center console.

It does have voice recognition for the Bluetooth. I thought it only "listened" if you pressed the button. This could cause the issue though? Any idea what the ANC mic looks like?

Probably a little plastic piece with a few holes in it...it might have a front and rear mic, I cant rememeber for sure. Once you pop that side panel just disconnect the ANC system, it's a signle gray plug. Theres a couple youtube videos out there I'm sure.

I think I owe you a beer, or a case for that matter. That did the trick. Wish I would have known before I spent 6+ hours fiddling around! Thanks so much!

No prob man! But next time I'm in Minnesota I might take you up on that!
