Sorry if this has been brought up before. I've tried searching on this site and others, but there isn't much specific info.
I recently purchased one of these units, and would like to install it in my 2003 Subaru WRX, however, I want to keep my stock head unit intact.
Is there any way to do this? If so, what do I need to install this so I can use it over my factory speakers in conjunction with my OEM head unit?
Any other tips on how to do this correctly?
-Thank you
