I finally got my install done yesterday, (serial # 00031). The unit is very stealthy and can barely be seen through my semi tinted windows, very nice!

The sound is just as good as it was when hooked up to my home stereo, that is until I turn the car on. :(

I have the same symptoms as described by Clark above. The EMPEG is installed in a 1995 Audi 90 V6 and attached to an Alpine MRCF303 4 channel amplifier. I have bypassed the factory amplifiers for the rear speakers. All the install directions were followed to the tee by Tweeter here in Boston. The unit does have a hiss even when attached to my amplifier at home and paused, but this is easier to ignore than the engine noise. We found that when we hooked the ground wires to the Amplifier ground there was still a lot of noise. But when we hooked them to the outside of RCA output of the amp the noise was reduced. This did not make much sense to us but did make the unit usable in the car, other than the engine noise.

Any help and pointers would be appreciated.
