You mention that you attached your Sub Pre Outs from the HU unit to pins 10,9,8,3 on the Amp. Do you not have the Infinity sound system? Perhaps this is why I am so confused by your directions. I thought all of these stock stereos had the same Amp. Or perhaps there is a difference between your year and my 05' Roadster.
Here is what I found that the pinouts should be for my Amp. Obviously 10,9,8,3 is not gonna work for me.
