Dash Speakers Specs

[BigRiz]

Hi, I'm thinking of replacing my dashboard Speakers. I have a Japan Vitz model, but I'm assuming most things are the same as in the European Yaris most of you own. The Speakers are producing distortion when I drive the volume up, especially where there is some bass. Here the car audio mugging situation is so bad that I don't want to put Speakers anywhere visible, and ideally I should not change the stereo.. I like it.. it looks like part of the dashboard.

Anyway. I found these top-of the range JBL 4-inch speakers. Specs here: http://jbl.com/car/products/product_detail...cat=POS&ser=POS

I have not yet seen the speakers that are in place so I don't know how they mount. For those who have changed those speakers themselves, do you know if the way the speaker in the image mounts matches? By the way.. how do I open the part where the speakers are? Are there any screws or something, or should I simply pull off the grille?

One last thing. Is the original head unit powerful enough or should I buy an amp?

The standard Hu will be powerfull enough to drive them but will sound better wit an upgraded HU!

They should fit fine as the dash Speakers are 10cm!

you have to prise up the plastic grill, dont damage the surrounding plastic

there is two screws holding the speaker in and are a real pain to get to, youll need a stubby screwdriver
