For a 92 it uses a standard GM harness. You don't need a ground loop isolater..you need an adjustable 4channel high/low converter designed for this kind of integration. Make sure you hook up the remote..which is also power antenna for that vehicle..wire the harness as normal and all should be well.

One more thing to note. This is an older vehicle and the speakers might be bad..also note this bose system uses a seperate amp on each speaker..and the speakers are 2 ohm.  If everything is not playing properly you should change all the speakers to standard 4ohm replacements and bypass the bose amps..which can be easily done at each speaker/amp assembly..no need to run extra wires, and in that case you also won't need any converters.

good luck

we i found out that the bose sys is amplified and it does need high/low inverter, its so the amp wont get to much current.  apently this bose system is a little diffrent then the current ones.   thanks for all the info.

make sure not to just hook up the radio to the speakers directly I had a customer bring me his car that he did that too and lets just say he fried a $400 pioneer deck and Im pretty sure that is not covered under warranty... lol

I dont care about who has the bigger name in the business... The Bigger the name the Bigger the price. NO BETTER QUALITY!!!

That is exactly why I stated in my first post that it needs an adjustable 4 channel high to low converter.

In my second post I clearly state that IF he replaces the bose speakers and bypasses the amps he will not need a converter.

Oh its one of those..still not that hard..just more work involved. In the trunk behind the carpet on the passenger side you will find the amp/tuner. It is a silver metal box and you will see wires and an antenna plugged into it.

You will need the following........gm antenna adaptor..144'' antenna extension...and a standard gm harness for 90-up. The speaker wires will need to be extended to the dash along with the antenna cable...grab power and constant at the ignition harness or fuse panel, unless you want to run it from the rear as well. You can ground it to metal under the dash and you are done.
