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!

The speaker wires coming from an amp into into the speaker don't have to be thick to be good. Those wires carry a high voltage, low amperage signal.

Amperage is what causes heat issues in car audio, not high voltage. you could run a sub with 2000watts of power and 22awg wire and be perfectly fine and not see a decrease in volume (due to loss of power).

the power & ground cables however are high amperage low voltage, so they produce heat, and have to be big, or else you'll run into diminishing returns & even safety issues due to loss of power in the form of heat in the wire (which can start car fires).
