2024 Subwoofer Bracket Bolts - Size, Thread Pitch, & Length Needed?

[Tim_CO]

I bought a subwoofer online that came with everything but the bolts needed to secure the bracket to the car. Can somebody help me figure out what the bolt size, thread pitch, and length of bolts I need? Also, are all 4 bolts the same?

Thanks - Tim
