I really have no clue where to get the power cable throughm this is going to be my first instalation, and this might be one of the most frustrating parts, because i dont even know where to start looking. Does any one know where to get the cables through? and i looked in the trunk and i couldn't find a good bolt to ground to, where is a good bolt?

I would ask this question on a Honda forum. I dont think there are a whole lot of Honda owners here.

Is there not a hole on the firewall anywhere?

Check for plugs in the firewall.
