I just got the new mazda 3 hatchback to replace my golf and of course I want to install the empeg in it in some fashion.

This car has an evil non-standard built into the dash head unit. I ripped the dash apart and there doesn't look to be an easy way to add a line in also this a totally new design so there are no adaptors yet.

I am trying to decide if I should use a RF modulator or if I should use a speaker to line level adaptor to hook the factory HU to the empeg and get an amp.

The modulator sounds the simplest and I could still use the stearing wheel controls to run the volume so I am leaning towards that but I am guessing it would sound pretty crappy.

Any input would be great.
