Need a little help guys. I promise I've been searching and haven't found much out.

I'm starting my audio build soon and I'm wondering if the non-bose for 05 coupe has a factory amp. My guess is that it does, but there's always a chance it doesn't. Naturally this will impact how I'll need to wire my component set.

 

The amp is in the head unit. THe BOSE system in the premium pkg has the amp in the trunk.
