Alternator whine can also be reduced by adjusting the line level input on the amp. Sometimes when the amp is turned up too high it creates this. Check ground sources, preferably only ground the audio units to one round and dont share it with sources like the headlights as those are known to cause a noise. Also you did not mention what kind of soundstream amp, I had an older (10y/o) one that I had in a prior vehicle that sounded great and worked flawless (no noise etc) but when I installed it in my Boxster I got a alot of engine noise. Took it out and installed brand new Alpine amps and no noise or issues. Just new technology is my guess. As far as antenna wire adaptors, use any german style ones will work.
