Firewall bypass

So I added an 8 gauge wire directly from the battery to the alternator. So the old wire from the alternator to the firewall and back to the battery is still present. Is this ok or should I take it a step further? I plan on updating the alt to a large capacity to run the stereo. The stereo/amps run directly from the battery with power routed to the trunk for the amps and a direct line to the tape deck. I’m guessing under load the power will take the storage route to the battery on the direct line appose to running through the firewall/ammeter. Should this new direct line be fused? Current alt is 35amp.
