So my 04 has the Bose system in it. I am looking to get this double-din head unit, http://www.amazon.com/gp/product/B001PAECYE

I am also getting the Metra dash kit so I can mount the unit.

I haven't popped off the existing face plate/stereo etc. yet to actually take a look at how the bose speakers all connect. So what I am trying to figure out is if I am going to have a problem connecting all of the speakers to the new headunit and also how the head unit will connect to the Bose Amp ( I believe there is one) or if I will have to do some serious speaker replacements etc.

I searched but couldn't find any fullproof results, thanks!!

 

wont be a problem connecting your head unit. i am not familiar with the metra kit, so i do not know if it includes the appropriate harness. i used the corksport kit, and had to use the metra 70-7903 harness, and a peripheral electronics sven 4 to integrate to the factory bose.
