ugh, it's a PITA!
although drilling holes and using grommets shouldnt be so hard. i just didnt think it would look as clean. (i never saw a how to myself, or pics of it done, just assuming).
i just tapped into the stock wires at the stock amp, when i removed that POS. from what electronics people told me, the guage of the factory wiring should be sufficient unless you will be running some serious power. if this is inaccurate, stereo gurus please chime in.....im sure you will anyway
