All my grounds for the big 3 upgrade

Where I placed my 4 gauge ground wires for the big three upgrade on the llincoln town car

1) Grounded to the Body / chassis 2) Grounded to the Alternator 3) Grounded to the Engine Body AKA BIG 4 Upgrade Nice work

Thanks for saying that...

Thats correct

Thank you for the video. What improvement did you noticed after the ground wires upgrade? I have a 5.4L 1999 Ford expedition that is giving a few problems.

I have a four channel 1600 watts amp all speakers upgraded including the 8 inch subwoofer. Rockville 1200 watts max- 650 RMS. before the big 3 my lights were dimming and I wasn't getting the punch from the subwoofer with other factory amp from ford. This new 1600 watt amp I get the punch but the lights were still dimming more. Now I get the best punch and no lights dim at all. this does improve on the sound system and current flow. Keep in mind I have two 4 gauge wires from the battery to the alternator.

It needs to be to engine block for the starter Why such big pos cables ?

[@Pantherforlife]

4-gauge wires the same as on the Mustang V8. For more and better current flow. Your right about the starter. I just didn't do it. Till this day I don't have a problem starting it. I've seen videos with 2 and 1 gauge wires. And those are huge.

@@Pantherforlife not many amps flow in pos starter cable

Mmkay Ain’t quiet the big 3. Your missing your wire to pos to alt. (1) is pos battery terminal to alt (2) neg batt to alt casing (3) neg batt to frame/chassis Good start tho but not a true big 3 upgrade . Because your alt is not pumping amps out of the ground.

[@Pantherforlife]

Your correct on that. The reason why I didn't do it because I never had a problem starting the car even now. I am more focus on the current flow to the speakers. A stronger punch to the subwoofer and speakers. No more dimming of the headlights and interior lights. I do have two four gauge wires with fuses from the battery to the alternator. This is my Big 3 upgrade.
