Does your 2020 X3 have iDrive 7?

1 - Can the plastic adapter for the power actually revive a 6 or 8 gauge power/ground? Cause it sure doesn't look like it.

2 - I have the 7dsp and an external sub amp (50 amp / 650w). Can I run a 100a fused 4 awg line to a block 4-5' away that splits it into two 8 awg lines for the positive? The 8 awg runs will be under 2' after they're split. Do I need a fused split or just a common 4 awg in / dual 8 awg out?

3 - can the ground from both subs be a 2' run of 8 awg run or does is have to be 4 awg because the positive is a 4 awg until it's spilt? The ground is a bare metal bolt almost directly beside the amps and would be simple to bolt both 8 awg ground leads to.

Thanks for your help!!!
