Okay several questions,
1st How did the head unit work with the stock set up? It looks like you used it for awhile before finishing your project.
2nd Can you put anything in the trunk now? I'm assuming you wouldn't want to set anything on the speakers/Amps (I'm a total noob at car audio)
3rd I want to see pics of the rest of your set up. I've been looking at your head unit.

Oh btw Looks fantastic
