AVIC F700BT installed

One more observation/caution:

I kept the Porsche OEM amp which was in the car (well actually it's a 6-channel amp from a 996, but otherwise it's identical). In any case: the level from the line outputs from the AVIC is not high enough to drive this amp, so the volume is kind of low. It's just loud enough in the highest volume setting. So I will need to install a Line Driver Signal Amplifier (a.k.a. "pre-amp").
This would not have been an issue had I bought the (more expensive) AVIC F90BT as this has 4 Volt line outputs

Hey Chris,

I recommend bypassing the factory amp and use the built in amp of the headunit. I found that using the line level speaker wires from the headunit direct to the speakers was by far the best option if you don't want to spend money on an aftermarket amp. When I had the cdr220 with the stock amp (HAES 4x40 watt), the sound wasn't quite loud enough (mouse squeek when your on the highway)..when I installed the Avic D3, the output level was still horrible. Sound inhibitor imho.

Anyhow, I remembered in my previous car I had a set of polk audio speakers that was wired direct to my Pioneer and it sounded awesome. So I applied the same logic here and am much happy with this set up than using the factory amp. You just need the color codes for the wires so you can tap into it instead of cutting the amp harness up...which if I look hard I'm sure I can find it again somewhere...otherwise, if you look at the actual speakers in your car, you'll see the colors of the wires as well.

My current set up, I have the dash and rear speakers driven by the Avic D3. And the door subs, I have it hooked to a Kicker 2 Channel amp.

Other than this, replace the factory speakers with something descent and you should be pretty satisfied with the results it produces.

Hi,

thanks for the advise. I started with the rear speakers (as this was the easiest to do, I still had the matching harness lying around from a different project) and it's a huge improvement. But now I am facing the dilemma that I have two pair of speakers (dash and doors) left and only one pair of amp outputs on the AVIC ....
So my plan is to drive the dash speakers via the built in amp from the AVIC and drive the door speakers with the OEM amp plus line driver pre-amp
