Removal of the Factory Integrated Source

Excellent write up! The pictures answered some questions I had about the wiring harness on the back of the stock HU.

With my car 1/2 torn apart, I'm still toying with getting a small amp to power my new speakers. Since the wires coming from the back of the stock HU are pretty thin, will running the same gauge wires to an amp help me all that much? Even if I upgrade the wires to a lower gauge (smaller the number the thicker wire right?) from the back of the HU to an amp, I'm still starting out with thinner wire. So, would it be best to run thicker wire from the amp to the speakers? I read somewhere else here on Yaris World that I may need a 'line out converter' and an 'amp wiring kit', anything else?

Hopefully it's OK to ask these questions in this thread. At this time I am not replacing the HU which I know would simplify everything.

Thanks!
