Kevin thanks for your response. I’ll take a look at that thread again. I do like the sound stage with door speakers providing the bass so I’d prefer to keep it the way it was set up originally.

One thing, the power comparison I was making was between the old and new head units, not between the new HU and Porsche amp. Probably irrelevant but leads me to another question: I think the original CDR220 was providing more volume coupled with the Porsche amp than I’m getting with the new Kenwood HU. I wonder if there was amplification from both the 220 HU and the amp (cumulativelyw), while with the new HU the amp is fed unamplified sound from the pre-outs so the amp is doing all the work (poorly).
