Radio question

These symptoms occur every time the car moves and stops, although I didn't notice it when I reserved the car.

A friend of mine has an 02 S that does almost the exact same thing - fine when he's not moving but cuts out when he starts to move. Stock radio as far as I know.

Forgot to put in my post, I didn't have this issue with the stock radio.

I used the Metra connector to wire the car and head unit. Does the Boxster have a speed sensitive wire in the wiring harness. I'm going to take out the unit and connect a volt meter to the wires, just wanted to get some ideas before I tear into it.

Any/all opinions welcome.

This is sounding like a power issue. I'd pull it out and run new ground and power wires (not using those for the stock unit).
Run a new ground from the stereo to a solid metal ground point, then a new wire from the switched power to the fuse box.

This. PW is exactly right here. I'd bet bad ground.

Turned out to be the ignition feed. The battery and ground were fine but the ignition feed voltage would fluctuate wildly when the was moving. I ended up splitting a line I was using for the HU and installed a switch in the 'batwing'. I have some pictures I'll post later.
