How can I run the power wire through on 91 integra back to the amp?

Question

I need to run the power wire through to the amp in the trunk for 91 integra can anyone help!!!! where is this firewall that everyone talks about?

Answer 1

The firewall is the metal wall in front of your dashboard between the cockpit and the engine bay. There will be multiple penetrations thru it from the factory. Try to find a large rubber grommet and poke a new hole through it for your power wire. If there is no existing usable grommets you will need to find a safe place to drill a hole thru the firewall and then put in a grommet of your own. DO NOT just stick the wire thru the metal without a grommet it will short out to thru the insulation in no time. Then pull up the door sills and kick panels and lift the carpet up and run your wire along the edge of the cockpit under the carpet. Run your power wire on the opposite side of the car from the signal wire so you dont get inductive noise problems.
