hello the radio in my land rover recently died.
so i went to best buy and bought a pioneer radio also a adapter that would take the two connectors that use to hook up to the original radio (one in the pic below) and break the wires out so i can wire in the new radio. well i did that and the radio works but i got no sound. according to the diagram on the adapter and this website :
Information about Car Radio ISO Wiring Harness Adapters
the brown connector should be left and right speaker connections. but it is not. do any of you know what this connector is for? and where do the wires on the connector end? i found that this car has a built in amp and thats where i located the wires that go directly to the speakers. so what i was think was using the 8 wire brown connector and connecting 4 speakers for lf,rf,lb,rb to the end of it so the adapter that i bought will actually work. and so i dont have to run my own wires. will this work? and can you please tell me where the brown connector wires go to? thanks!

 

What system came stock? does it have an amp under the driver seat. If so, you need to make sure the amp/antenna boost wire is hooked up to the blue/white wire coming from the head unit.
