I just installed this yesterday on my 2024 Toyota Tacoma with factory JBL system. I am not a audiophilac so my ear is not fine tune for someone who would consider themselves as an audophiliac. I was a little bit disappointed with how the factory JBL system sounds but it got the job done. The Beat Sonic device do makes a difference. Some songs I would listen to at 30-35 volume level with the stand a lone factory JBL system. With the Beat Sonic device installed, I now listen to the same song at a 10-15 volume. The bass is now elevated but it's too much for me on certain songs when I just want the vocal to stand out. I set the gains configuration same as in the video but I think it's just a little too much for me. So I will have to play around with the gains one of these days.Just saw this, anyone gotten such a thing? Did it make much difference?
