someone at Honda understands audio systems.

He was my grad assistant, but recently left to take care of his mother who has dementia.

i've hit a point of discussion.

this amp location means cables will be passing near the magnets on the rear deck woofers. i see that as undesirable.

So what exactly makes you think this would be a problem?

magnetic fields manipulate electrical signals in nearby wires.

in the install, all signal cables will be routed away from electro-magnetic sources (motors and magnets).

So what are you doing behind the HU as far as avoiding the motors from the heating/air system? How are you determining the optimum safe distance from these potential sources of noise?

avoiding the HVAC system is easy, I route RCA's down the middle of the car to avoid signals on both sides of the car as well as the HVAC system behind the passengers side dash. I will avoid the fuel pump also. Distances from noise sources will be as far as practically possible.

in this car, the HU will be below the factory HU in a hidden pocket, acting as a pre-amp for the most part. The only noise-making module down there is the SRS module. It's in a metal casing so it's mostly self-shielded. Twisted/Shielded RCA's will help with noise rejection along the run.

My harness runs down the middle in my Civic, and creates enough RFI/EMI to make you sterile.

Honda fuel pumps are nearly as bad as those in older ford pickup trucks.

Since it's a point of discussion...I can see keeping signals away from AC or pulsating DC sources, but what kind of interference would a permanent magnet cause? Don't high-end home audiophiles use ferrite beads to block/absorb RF interference?

And these snap on cores

Isn't there a magnet on the speaker.....right next to the speaker terminals?
