Hey All, I'm going to be installing a Z110bt in my Saab in a little while. I've read that you need to add (2) ground loop isolators to avoid the "pop" when shutting the unit off. There are a lot of ground loop isolators out there, can any of you recommend a brand that's better than the rest and easy to install? Something you've had good luck with? Thanks

Doesn't anyone here install their own radio's?

Maybe you should ask that question wherever you read that you need to add ground loop isolators. They are all about the same - low tech and cheap/easy to add if necessary. I don't need one, never had a pop. Just rca in - > rca out for each line-level channel. BTW, in the past I used it to eliminate a hum, not a pop. It is a "last-resort" type of fix becasue it does seem to affect the audio (slightly).

Thanks, I didn't know they were all about the same. This topic first came up on a Saab forum, where people were experiencing the popping sound when turn off their key.
