I have a 21 TLX advance. I am trying to install a sub by using the pre-amp signal(clean signal). From my previous Honda accord, I did not have to unplug the ANC and no strange sound from my sub when I used the clean signal. I look by the front passenger area and in the trunk.

Do you know where is the factory amp?

Welcome to the Forum Marjels.

It is behind the Glove compartment on my 2018.

I found the detailed instructions for all speakers and amp locations and wiring diagrams.

If you would like a copy, PM me with you email address.

I look under and behind the glove box still no amp. I found these plugs(pic below) and I thought they were coming from the factory radio but after I unplugged it, I was still listening to the radio.

I wanted to try the preamp install since I like having ANC. I could have tried to look in the rear panel but I will wait until I have the right info about the 21 TLX advance amp location and since where I live winter is around the corner, maybe I will be able to finish the install sometime next year.
