there is no specific hole for this. use an existing rubber seal in firewall. take thin screw driver and insert in seal , stretching seal enough to push wire thru. seal will close around wire when you remove screwdriver
To install an amplifier in a 2011 Mitsubishi Lancer, start by disconnecting the negative battery terminal to ensure safety. Run power cables from the battery through the firewall to the amplifier's location, typically in the trunk or under a seat. Connect the amplifier to the car's audio system using RCA cables and speaker wires, ensuring all connections are secure. Finally, reconnect the battery, adjust the amplifier settings, and test the system for proper functionality.
The battery charger can be used but it is not recommended. The battery charger does not have filtering on the its output like a power supply does. You will probably hear an AC ripple on the amplifier which will become very annoying when listening to the amplifier.
The battery or/and some of fuses are dead.
You need to pass it under the car just under the passenger floor mat you have a hole just the right size for the cable
You have to disconnect the negative cable from the battery.
Is the battery fully charged?
Straight to the battery through your firewall straight to the battery to the to the positive post
To install an amplifier to an Impala head unit, first, disconnect the negative battery terminal for safety.

Connect the amplifier to the vehicle's audio system using RCA cables for signal input, and wire the speakers to the amp outputs. Finally, secure the amplifier in place, reconnect the battery, and test the system for proper operation.
Question: Can a power amplifier amplify the power? An amplifier can amplify the voltage or the current. Power can be converted to heat.
A voltage amplifier does not have to supply significant current bur a power amplifier does.
