Power Wire Run from Battery

Has anyone ran a power wire from the battery down the right side of the car for an aftermarket sub amp install? If so, any insights into where the wire was routed through the firewall and rear seat?

I am just not very thrilled about tapping the rear distribution post. I know it comes from the battery, but standard practice for all amp installs is a dedicated and fused 12v line from battery.

The plan is to install a MATCH UP DSP and an aftermarket sub amp. The aftermarket amp is fused for 100amps. Power up to 1100w rms (very reputable brand).

Hey, just wondered if you worked this out? I’ve got a Musway I want to install in the rear but run power from the battery in the front. Hoping there’s a secret easy route to run through the bulkhead.
