Where to ground my amp?

[IrishMike]

I have a 2003 Acura RSX and the amp will be in the hatch next to the box

I have a Fostage 500x1D amp but not really sure where to ground it. Just drill a hole where the spare tire is? Use a bolt to secure the ground?

pics of the metal nearby where your amp is?

do you have any sort of thick metal frame support that runs directly up to the front firewall of the vehicle without any major spot welds or other electrical inhibiting factors in the way?

you're only running a small load so its not going to be too picky imo

wire up the amp itself with remote and power wire. use your multimeter and set it to ohms. 200 setting i believe. take the positive lead and place it on the amps GROUND terminal. and then take the negative lead on the multimeter and place it anywhere in your trunk. try to find a spot that is thick metal and is close to 0 ohms. i happen to find that my seat belt bolt is pretty good for me at 0.3 ohms so i chose that spot.

It would have to be in the trunk somewhere. I found a metal frame spot at the rear. Might just drill a hole there.
