i have a 97 chevy malibu and i need to know where to run the power cable through the fire wall. or where could i get a diagram that is simple enough for me to understand...
Either find a rubber boot with enough space through it (where your steering column goes through), or drill a hole and use the grommet that comes with your Amp Install kit. If you choose to drill, MAKE SURE you have enough clearance on both sides.
if you can fit under you dash you can see that mostly all cars and i say all cars becuase iv been doing this for over 10yrs and all cars have a wire that comes from the stearing colum that goes through a rubber gasket into your engine. What we do is the gasket already has a hole in it push your chair as far back as can go and shimmy under the dash bring a flash light becuase its sometimes hard to see and youll see a round black rubber type thing with a wire already running through it. Thats the one to use you might need a long metel thin rod or use a meter coat hanger. Using black electrical tape, tape some of the power wire to the tip of the hanger and push it through the exsisting whole as far as you can then go into your engine and you should be able to see the wire then just pull it to the length you need to wire to the batter dont forget to install a fuse at least 30amps or more depending on how many watts amp your running it for. Dont worry if the little round gasket pops out it can some times do that once your finished with pulling it out and you know your not going to be pulling on the wire again. Then you can actually push the gasket back into place that only if it popped out if it didnt then your good to go.
As mentioned you should be able to find a hole already but I like to drill my own and keep all of my electronics separate from the other factory wires. It should not hurt anything to run them with the other wires but you could get some induced current plus it makes it easy to keep track of all your stuff in case you would need to take it out. 2 things to keep in mind no matter where you go through though 1 make sure you have a bushing in the hole to protect the wire and 2 be sure to run your ground beside your power wire, dont separate them too far.
