Deep bass sound coming from subwoofer

[Gerry Mitchell]

I recently installed a 10inch sub and Rockford distaste amp in my 2020 Honda Accord. When I accelerate, I hear a deep sound coming through subwoofer. But it only makes sound with windows rolled up. If I crack the windows, it doesn’t makes that noise. Could someone help please? I checked all the grounds also.

I checked all the grounds also.

If the amp is wired with RCAs, try to run them over the seats for testing.

It’s wired with RCA’s through a line out converter

Sounds like the ANC to me as well. I bet a car specific forum will have an answer.

Try turning down the gains on the line-out converters. I have seen this happen before, and that was the issue. If you turn down the converter's gains, you may have to turn up the amp gains.

Not sure about Hondas inregards if theres a way to turn off the ANC within the head unit.
Alot of the toyota guys use an inexpensive device from amazon called Carista.
Thats what I used to turn-off ANC on my tacoma

There is information on the web that shows how to disable the ANC permanently and temporarily.
Good luck.
