Hi guys,

I was used to a nice touch screen with bluetooth and iphone connectivity, so that's the only thing I really miss from my previous car Don't miss the diesel noise

I am looking into fitting a Pioneer HU (8400bt) in my Cayenne 2005 with Bose, but to keep the Bose amp, I apparently need to use a 650dollar interface for that route? So maybe upgrading the Bose amp but keep the stock speakers would be a better investment since it would cost about the same or even less???

Or did I miss something?

We will do it ourselves, my best friend is an engineer, so we will be able to fit everything into the Cayenne, but a few questions before we start taking the interior apart to see how it all works :

What I want:
- Pioneer HU
- Upgrade tweeters at the front
- Keep stock speakers and if possible Bose Amp
- Upgrade the Bose Sub with a Pioneer (the flat 200w one with integrated amp and volume controls by remote)

Without using a MOST interface??:
- Can I maybe replace the Bose amp in the trunk and re-use the speaker wires or are they filtered by the Bose amp??? This way I would for instance add a 6-channel amp between the HU and Bose Speakers... If that's possible without having to run new speaker wire to all speakers etc...

- If that route would work I would also delete the Bose amp with Sub and upgrade the Sub with a Pioneer flat one with integrated amp...

Any insight would be very appreciated

 

So the real queste is to know if the speakers can just be connected to a new amp with the existing wiring??
