The new DSP amp needs a 50 amp supply.

The old amp has a 40 amp fused supply.

I decided just popping in a bigger fuse and praying wasn’t a good plan.

Normally you just add a thick cable with an in-line fuse and bolt it to the battery positive terminal.

Tried to be neater..I saw that adjacent to that battery is a red box..it’s the main distribution point for ultra heavy current distribution.

I saw one ‘slot’ was free but no ‘spade’ to plug into was free.

So I bought a used one to take apart and cannibalise..unfortunately internally it’s not just one bus bar but two bus bars separated.

Not to be defeated I’ll still use the idea but attach my new amp feed to the main bus bar and route it via the blank port..
