CDX-3170 (LOUDNESS)

[Marlon]

Good night friends, I'm a brazilian boy, I have a Sony CDX-3170 in my car, but I don't know how to activate the loud, I tried in all ways but I couldn't activate it, I need it very much because my sound is good but I need more bass and the loud function will help me very much, what button I must press to activate the loud function?

Please, send me an e-mail to [email protected] because I read my e-mails with more frequence than I open the forum. My father will be surprised with the loudness.

Sorry by my bad Englis, I'm doing an English course but I don't know every things yet.

Thank you for the attention.
