i have a 00 coupe... when i had an amp in there it was grounded underneath the rear seats... look around under there for a good ground location.This is going to the ek hatch guys out there. What is a good spot to ground the wire for you amps? By the way my amp is located in my trunk. Let me know guys!
Ground wires are not meant to be long. They work best when theyre under a foot long. From what i've heard from the local honda guys in my city, best grounding spot they've come across is the rear seat belt bolt.
