Default 2012 Accord Daytime Running Lamps causing noise through speakers.

My speakers buzz until the headlights are on or the high beams are selected on. Ive recently installed a stereo system which consists of new component speakers with crossovers in the front, LOC converter under passengers seat & Amp in trunk. Even with the stereo off I get a buzzing out of the front speakers and a bad buzz out of the aft right speaker only. Ive disconnected the power line into the crossovers and the buzz is still there. Until I remove the actual speaker wire from the crossover the buzz is still there, I guess the DRL has bleed over into the crossover unit? Any suggestions on fixing this? I read the DRL is basically duty cycling the high beams to make them dimmer. Im pretty sure this is the cause of the noise. One item I haven't tried is moving my crossovers away from the under dash fuse boxed to which I read is the location of the circuit for the DRL. This might fix the front speaker buzz but I cant figure out the aft right speaker buzz with the DRL on. For now I have to drive around with the lights on.

yes, move the crossovers, put them next to the amp or under the front seats or in the trunk.

inductors (used in the crossovers) are also antenna for noise.

however, the noise should not be very loud without the help of the amplifier.

where is the LOC?

how did you develop a remote turn-on? the amp should be off when the radio is off.

make sure the RCA's are not near the DRL controller either.

how/where is everything grounded?

Finally fixed. Turns out the LOC has a bad channel so I just moved the 2nd channel input/outputs to the third channel. Also moved the front speaker crossovers to under the seats and all buzzing is gone.
