That Pioneer AVH-P4000DVD is freakin SWEET.
You're getting another head unit, does that mean you're getting rid of it?

 

Thanks I'm getting the XM unit that plugs into my avh-p4000, not replacing it yet

Also about the visual mods, I don't know what to add. Right now money is extremely tight, but one major thing I want to do is swap out the engine/transmission for something 10x more powerful

I've been looking at MAYBE getting a trailblazer SS engine put in, its the corvette v8 engine
