Hi Chris,
Currently im planning on upgrading my front and rear stock speaker in my vios trd 2012.
Im still using original vios trd HU and stock tweeter inside the side mirror.
I dunno what size of original speaker, i just want to change the stock speaker without modified the casing. Like to hear crispy and clear sound...
Can u do me a favour by suggesting a few brands that can fullfill my requirement for front and rear speaker vios trd 2012?
