I also have managed to use my portable CDP in my car. 
It has it's advantages :

1. Easily comes out of the car. (To avoid theft)
2. Relatively clean sound.
3. Can be placed on the passengers seat instead of being bolted to the
   frame. (To avoid skipping when finding potholes)

But unfortunately it has it's drawbacks:

1. No balance control. (probably coming soon on new portables)
2. Need for power adapter. (I don't have a Sony. My unit runs on +/- 6 V)
3. Being careful with the discs is a bit difficult when driving.
4. Not being part of an integrated system, it does have a small amount of
   distortion. (Although it's probably attributable to my $50 equalizer)

To hook it up in my car, I installed an equalizer with AUX inputs (aside
from the direct speaker inputs). 

I encountered two problems:

The output of the radio was made to drive all four speakers in the car
with floating ground (balanced transformer something). My EQ was only
set up to accept one pair of speaker leads (i.e. rear only) and the
inputs were set up to accept common ground signals. 

I ended up hooking the rear outputs from the radio to a common ground/
floating ground adapter (about $10) and I left the front speaker
wires unconnected.

I then hooked up the 1/8"/RCA stereo jack supplied with the CDP to the
AUX inputs on the rear of the equalizer/amplifier.

WARNING!!!! If you do this, be extremely careful that you don't turn
on the radio and CD player at the same time (Sniff, sniff). At least
I couldn't on mine because I had no manual overide switch.

Try and spend more than $50 for an EQ/AMP. My S/N ratio isn't all that
great.
