[QUOTE="grandam888, post: 7156056, member: 628519"] im not sure if you need to be installing car audio if your trying to run your B+ wire from your radio or cigarette lighter. but if you must go on doing it yourself, you can run the wire through the firewall by using a coat hanger through the existing grommets in the firewall, then taping your 8 gauge to the coat hangers end, then pull it through. or you can use a fiberglass rod made for fishing wires though ceilings, or a fish tape. Or you can drill a new hole, but be very cautious on where u drill it as you take a risk of drilling a hole through your heater core or other important parts in your dash/engine compartment. and be sure if your make a new hole to use a rubber/plastic grommet as over time the jagged metal of the newly drilled whole can eat through the wire insulation and directly short the power wire causing your car to catch on fire/ or blow the inline fuse @ the battery be sure to use an inline @ the rated slightly above amperage of amplifier. If your amp has 2 25 amp fuses, go with a 60-70 amp fuse inline for safety. [/QUOTE]
