Hi, I've been dealing with a bit of a whine coming into my system after having the engine on for a couple of minutes. I've already tried searching various forums looking for other posts w/ a similar issue, but I haven't found any.
I'm running a Pioneer AVH-2550NEX headunit
Alpine PDR-v75 four channel amp
Kicker KX 800.1mono amp
4 gauge power/ground wires
12 gauge speaker wire for all of my drivers
- I'm using a wire from accessory to trigger a relay for my remote wires
I'm also using a power/ground distribution block to power and ground my amps
I don't have any noise when I play audio while my car is off or engine is running. I will only get noise when I keep my headunit on after shutting my engine off. I have to move my key from accessory to the off position to stop the noise because simply powering the headunit off and back on doesn't stop the noise (if the key isn't moved from the accessory position)
Disconnecting the RCAs from my four channel amp will stop the noise
My head unit is grounded to its mounting bracket, which has a factory ground wire connected to it as well.
I already ran a cable from the grounds of my RCAs on my deck's grounding point.
The RCAs are new
The headunit was recently replaced (warranty replacement because of a blown pico fuse)
My relay is grounded to my ground block
RCAs do not run parallel w/ my power wires
I do have an extra ground cable from my negative battery post going to my inner fender wall, which I'm now thinking about removing.
Again, the noise only comes after the engine has been shut off.
Thanks in advanced for any advice
