You are correct....The Big 4 will be motor to frame or frame to body for vehicles with body on frame.. obviously. I personally run alt case to batt - and chassis to batt - (in my case the "Batt" is a cap bank but tomoto. He really didn't list the big 3 very clear, he side tracked and should have shown on a stock vehicle or not one with I don't even know the mess he had going in that. There is certainly no over doing it per se' but there is a point where you are pissing money away and nothing against him but he hit that especially with neohoe if he is running 20 runs that's enough for 15 400a alts which I'm pretty sure almost any engine would just go nope and shut off from that drag lol

[@lilchrispy01]

@THELIFEOFPRICE I'd also mention that if the alternator doesn't have a ground post that indicates it's grounded to the engine block through its casing. Therefore you can use any mounting bolt on the block as source to upgrade the alternator's ground. Also, there should always be 2 grounds for an alternator, 1 from battery to block, and 1 from block to chassis. The chassis ground assists the uncharged ions from all the electronics in the vehicle to get back to the alternator to be recharged into electrons and the battery to block ground assists in better charging of the battery itself. Hope this helps 👍 keep up the hard work you've been an inspiration for me since the beginning and I love watching you continue to grow in the industry 👏✊

Alternators are always grounded through the casing and always hard connected to the engine. The ground tab is for convenience.

The big 3 is mainly for high output alternators and vehicles that have piss poor wiring(like chebby trucks and suvs) thin wiring or deteriorating grounds (like braided ground straps that are old and many strands broken) Ford usually has very adequate wiring for FACTORY charging systems and use braided strapping on the hood and trunk lid(obviously not applicable in your F150.

Considering literally hundreds of millions of cars have been made, for public consumption for over 100 years, and still no fuse! It's definitely not needed. Maybe we should put a fuse for every two feet of power wire in your car, for all the power wires. It's paranoia is what it is.

Bit late to reply but you absolutely can! Any larger wiring helps with current flow and in turn results in less resistance for your charging system. In most cases you’ll get 10 - 15% extra out of your factory alt.

Is it a good idea to install a battery isolator between both batteries?

[@ChaosTherapy719]

It can be done, but it's not necessary. The more breaks in the wire run the more energy bottle necks that occur when trying to feed the accessory batteries and amps. I used to use an isolatator when i first built my system, but later eliminated it and everything runs perfectly fine without it.

Thanks

Now i only have two 300 amp ANL fuse bocks, one 18" off the main battery and one off my accessory battery to protect my amp.

So if I’m not running a battery isolator In between starting and system battery, is it ok tu use a AGM as starting and lithium for sound system ?

[@bygboie]

Can we see a video of running a AGM Battery to a D4S Lithium battery cause that's what I'm about to do in my 2019 Chevy Trax LT to run a JP23 on 2 8's

big3/4 or capacitor? what should i buy first and why would be a good video. Since allot of people do not understand the difference.

[@shadebike1594]

With my minimal knowledge of bass systems I’d say big 3/4 caps don’t seem to help as much as big 3/4 but there’s plenty of videos of people well more knowledgeable than me

@@shadebike1594 i have a big 3. would rather any car audio advice, that avoids the use of capacitors. deep cycle batteries on the other hand.....

[@shadebike1594]

@@Naferner_Said deep cycles don't seem like a bad start but i see a lot of people going lithium banks instead for more future upgradeability

[@basspowerish]

Do you have a main location where you do installs??
