Choosing a Line Output Converter?

[Bozios89]

Im looking to add a 4-channel amp to power my rear speakers and possibly a sub in the future.

Would I want to use a 2 channel LOC or 4-channel? And if you dont mind explaining why so I can learn in the process.

sorry if its an obvious answer, im new to all of this and trying to do it by myself

Thanks

You should get in touch with Crutchfield.com. They have great sales and technical help and will let you know what works and what won't. Their prices are fair and they usually give you all of the adapters and instructions when available.
