I don't want to drill a hole unless necessary. Is there a location somewhere on the firewall to run the wires through?

 

On the left side of the car, there is a rubber grommet. Push your power wire through this hole.

 

good info. thats wher ei pushed my power wire through also.

 

the dillweed that had my car before me drilled a hole on the passenger side of my car just to put one tiny *** wire through

 

Kinda hard to explain but here it goes.
Feed your wire through the hole from the engine compartment into the fender area and then into the cabin through another hole thats by the ecu.

More little more difficult than the route above. Still requires no cuting or drilling.

 

Great thanks Guys! Kinda thought that was a hole but don't want to go around chopping ****!

Thanks too func-tion, I will consider that too.

 

tsk tsk tsk boys, your car won't be legal for stereo competition.......power has to be run down the battery side of the car
