Computer Audio to Factory Amp Options

[mportobello]

How do you connect 4 channel audio from a computer to a factory amp?

The computer has 2 miniphono plugs, front and rear stereo. Using an adapter/splitter I get 4 RCA connectors:
front left
front right
back left
back right

I have got a wiring harness that I believe connects to the factory amp (American International TWH-950). It has 8 leads for:
front right positive (+), front right negative (-)
front left positive (+), front left negative (-)
back right positive (+), back right negative (-)
back left positive (+), back right negative (-)

For each RCA connector, can I connect the associated the speaker leads with:
RCA center conductor -> positive
RCA shield -> negative

do you not have rca input's in your amp?? other then not, its not a great idea to splice rca's an wire then up. but it will work

I don't believe the stock amp has RCA connectors. Is that correct?

You answered your own post. Yes you can strip the RCAs and connect them to the harness. The harness should accept low-level signals, like the ones from the RCA cord.

Is it speaker + to the RCA center post and speaker - to the RCA shield?
