BTW, The factory stereo power lead is completely inadequate for powering a modern high power head unit. If you are using the factory power lead, you are only getting 85% to 90% of what your stereo will put out The factory power lead is very small and cannot handle the current draw. I too have a high power modern deck, and after replacing the power lead with an amplifier power lead, I noticed alot more punch in the bass, and better power overall.
