New System in the Grand Marquis (Build Thread)

The same length of 20 gauge wire will read the same resistance.

 

you also need to test the the resistance at your grounding points on the chassis to see if the resistance is less or not. to be honest though eazy i used to have a '99 lincoln town car which nearly identical to your grand marquis, and i know it has a solid frame all the way through so it may be better for you to just ground it to the chassis. but i never had a system in it so i never had a need to test it myself.

 

if it has a solid chassis ground it to the chassis...you have nothing to loose there, and if u can do em both(thats if u got the cash). cuzz iirc copper is more cunductive than steel ...but who knows

 

pics?? lol

 

my friend just picked up some knukonceptz kolossus 1/0 gauge. pretty nice stuff.

 

And please dont forget the fuse at the front and back battery. The ground from the front to the back battery is not necessary (but it wont hurt anything either). A chassis ground is more than enough for both batteries. The ground for the amp needs to be near the rear batt ground. In fact I like those grounds to be next to each other. Also those grounds need to be nut and bolt.

 

Nice i might do a 0 gauge ground too, but measuring the wires resistance like that tells you nothing lol. You have to add voltage to the equation then by how many feet and what gauge. Every foot of wire you lose power due to resistance.

 

my car is all peices welded together too, i really don't like grounding it back there.

 

well i was checking the resistance for the ground...for the power wire the more you have the better. on my van im gonna use 2 runs of 0 gauge for the power wire to the back batteries and eventually add more.

 

yes only a fuse between the power wires

You can ground the amps to the battery negative

Its kinda preference

 

Um...did you just pour a bunch of wood glue???

its going to take weeks to dry and it will shrink down QUITE a bit.

You should have made MDF paste and used that.

 

so you did like glue 45s??

 

well i dont know much about resin but i think it all depends on how much hardener you put in the mixture but yeah i think that replacing it with resin will be much cleaner lol and a lot faster
