You can always use the cd changer mounting holes under the trunk carpet liner on the drivers side. There is an indentation there as a marker so you know where to drill no interference with any brake lines body panels...nothing

 

Oooooh. I didn't know that. Thanks Neuman

 

Thanks Neuman. Have a big favor to ask someone. Does anyone have a pic of the area? I've covered my trunk in paint-on sound dampening. Can't see indents at this time.

Will dig around and see if I find anything.

 

this should help for anyone else interested. The directions show where the drill spaces are located.

I'll measure where it is for you, I have the oem cd changer installed so it's an easy task

 

Hi Neuman, Based on the link provided and the information you gave, I found the drill space. The measurements might be useful for those in the future asking a similar question. I really thought it would be smaller but it's quite obvious. I was going off my memory instead of checking the car before posting. You can send a smacking my way.

Have a good weekend,
