I have some spare money atm and found a pioneer avic-z120bt for a good deal and plan on eventually in the next 2 months doing the rest of the system. I would like to use this new headunit right off the bat so the question is should i keep the bose amp and just run some low level rca's from amp to the headunit or take out the amp and just run new speaker wire to each speaker from the headunit. Dont mind taking the car apart more than once between installing this system over time. Thanks!

 

Rip it all out and start off fresh

No point in ripping everything out multiple times and putting wear and tear on interior pieces

 

Wait until the amp arrives and install it at the same time as the headunit.

 

Yeah might as well. I could always lay down all the wiring so when everything comes i just mount it all in there but meh whats a few months i guess. Or should i just wait and get the 2011 headunits if they come out in time?

 

I think they're getting ready to roll out replacements or updates for the Pioneer 3200 and 4200 units, as their prices dropped pretty heavily. Pioneer usually brings out new units around march. If they do bring something out, I wouldn't be surprised at all to see Pandora support for iPod in the lower units, but few other changes.

The update for the z120bt probably won't be due until may or so.
