Vehicles with common ground audio systems, RF+ LF+ RR+ LR+ (-), i did an old beemer the other day at the shop, when i pulled out the old aftermarket deck and looked at the harness, it had some small capacitors and crap in wires and other random wires going someplace, now my question is. Is it possible to rewire common ground systems with capacitors properly and if so how is it done?

Thanks

With capacitors, no, you need to transformer-isolate the speaker leads. It is much easier to simply use the proper OEM integration device from a company like PAC audio or Peripheral. They make several devices designed to convert common ground systems to floating ground.
