Technical Dualogic gearbox causing static/hissing right tweeter? HELP?!?!

Hi. If it is not a tuning issue( although I still think it is) ,the other thing could be " loose " wires to the speaker, again you have probably already checked. Must admit it's had me thinking. You appear to have a good knowledge of audio which is above my level. Best of luck. I had another thought. I bet when the garage did the service they disconnected the battery. Reading posts in the forum disconnecting the battery can cause some most unusual consequences(cannot recall hissing noises ).Have a look on the forum re battery posts. Hopefully someone else on the forum will be able to advise further.

Thanks Arthur, will check speaker wires - got a mechanic who was also a car stereo technician expert for a while - good combo, will also check with him.

Will give that a shot and see how it goes. By the way, the website was down for me for like 2 days? - was it offline for anyone else? Thanks

Yep was down for me too and has logged me out when normally I just click the bookmark
