Unfortunately my fuse box sits under the hood. I can't find a hole in the firewall any where.
Fortunately, I do have a factory amp box for the stereo behind front seat and it has a 20amp fuse slot and currently 20amp fuse is in the slot for the amp.
My question is that, if I purchase "add-a-circuit" module and splice the HOT wire on the add-a-circuit module with the hardwire kit, would it work?
Add-a-circuit module will need to have two 20amp fuse. Hardwire kit came with it's own inline fuse. If I was to splice it in to the add-a-circuit HOT wire, will 20amp too strong for the inline fuse for the hardwire kit? Will it blow it?
