best place to ground sub amp in trunk

[ibanez78]

hello, i'm wondering where the best place to ground my amp in the trunk might be. right now i have the groud attached to the piece of metal where the rear speakers are but i'm getting a crackling noise from my speakers so i guess i didn't chose the right spot. any help would be appreciated

I usually look around for a larger bolt/nut that's hidden out of sight but attached to the body, buy the correct size wire connector and attach it. Also the shorter your ground the better and it also eliminates the chance to pick up any additional noises.

I used one of the bolts thats hold the bracket for the seatbelt. Its right under the seat back and was a 12mm I believe.

Seatbelt bolts work best.
