and no nav tv zen module.......

No, but I have a non-B&O, base model system. I think they used locpro advanced t harness.

all the ones i have worked on, had the b&o system it doesnt sound like the fake engine noise becase the harder you mash the gas, the more the noise enters into the cab. you said it goes away at higher rpm. as far as anc, thats usually a different resulting sound. how is they system wired?

 

[mikestan21]

It sounds like it goes away but it might just be overtaken by the engine and real exhaust sound at higher rpm. Each amp has its own 2 guage line to the battery. The signal goes from the head unit into the vxi amp then out to everywhere else from there

 

[mikestan21]

It is odd that if I turn the gain down on the bass control knob, the noise disappears. I wouldn't think the fake engine noise is limited to low frequency.

Hell going on in here?

Title is misleading

 

[The Car Stereo Company]

sounds like a wiring issue. either a ground or an rca cable. probably start there first

 

[mikestan21]

Okay, appreciate the help. If the Forscan fake engine noise disable doesn't work I'll take it back to the installer shop and suggest what you mentioned.

Figured it out in forscan via the ACM module.

727-01-01 xxxx xxxx x*-- 0 = ANCM Disabled • ANCM Disabled • ANCM Disabled

This got rid of the low frequency fake engine noise/active noise control I was hearing through my aftermarket sub.
