I have two 0 ga runs no problems.except near fuses panel inside , you have to really keep it clear of pedals and fuse box , remove seats and do it right it must be taped / tied down its big enough to wander , never pass thru metal without grommet ( it fits fine thru factory grommet ) spray silicone and fish tape or old ford antenna works well to guide it , cut the nose at a slant before fishing it make it easier it wont catch on everything , go under the rear seat metal frame by seatbelt but stay clear of those and enter boot carefully a few choices exist but try to cross factory wires at 90degree angles

and engine bay do not cross shock tower and dont use the path the engine fusebox takes or noise will enter , fuse at battery alway it protects the car not the amp

0 ga will carry 300amps roughly max

Grounds must be 0 on battery to frame

And 0 ga on amp end too

Parts ,

Gaffer or black duct tape

Spray glue , spray the floor pan let sit for min then tape the wire down , just tape wont hold it in place

And dont spray glue the wire too or you'll play hell to remove it if you need to later on

zip ties

fish tape or cut off ford antenna. Solid steel kind cut off ball and use the other side as handle

solid connectors !!

split loom to protect on some spots

Grommets if you decide to drill ? Not required if you use factory grommets

snap knife to slice grommet a bit

Quality liquid electrical tape to seal grommet area if required or black rtv , if your careful you wont need it

Spray silicone to make life easy

Electrical tape to tape wire to fish tape

Pass under all frames inside car away from seat bolts /slides and not in the middle of carpet or it will wear thru it or leave lumps

Upgrade battery

And all grounds to alternator / frame

4 ga battery to alternator fuse and alternator to fuse , ground alternator frame bracket to battery 4 ga

easy done

Hidden Grommet in the corner near accelerator cable , brake cylinder corner you can use the accelerator cable loop on the shock tower to guide the wire around above the fuel filter

Its tight which is why you need fish tape or something to bend and arc thru the hole you slit in it , comes out high above fuses inside the car and takes a while to get the path clear of pedals and fuses cover , dont try to rush it or it could be unsafe under your feet

yes Gtt , iphone no photo syndrome damn thing

maybe tomorrow i can take some and post up off pc , the grommet is buried back behind metal bracket thats screwed on in the corner

[r34unit]

any luck with the those photos ?

still cant find it! i must be blind or its right in front of my face !

[Carbon 34]

Sorry got busy

doubt you will be able to see the hole in photos the thing is buried behind brackets and cable and other items

But will try in a littlewhile to jam a camera back in after the batteries charge up

[r34unit]

ok i still cant find it i must be over looking it

is the grommet on the fire wall or on the left hand side ?

[Carbon 34]

Sorry iphone cant post photos easy

The grommet is behind the bracket buried back in there. Take off the bracket mounted between firewall and drivers shock tower !! you will see it

in the next day or so that fender is coming off my car so I'll post up the photo with laptop

Pretty sure its already online and sau under blitz return flow fmic install on gtt !?

Try the hole in body in the corner under the bracket , if you slit it and run a fish tape it comes out above the fuse block inside

Take off the trim so you can fish it out and guide it away from ( below ) fuse block and gas pedal

dude its a crappy iphone nothing is simple

See the blue plate

See the cadmium plated ( goldish) bracket with a ten mm bolt next to the grey plug ?

Unbolt that 10mm bolt tip the bracket out as far as you can and look down there is a hole in the chassis about 100mm in diameter with upside down grommet when you poke your fingers in the hole you will feel it

Get a fish tape or heavy coat hanger with a pre bent arc , slit the grommet big enough for a tight fit , spay with silicone , cut 0 ga on a single angle , tape to fish tape so all copper is covered and a bit further back better too much then not enough

Once silicone hits it you wont get tape to stick again

Spray the wire with a rag behind your spray , smear it up and down the wire you may need to do that a few times

Feed wire from engine bay towards back

Fuse it and connect after its finalized in boot

0 gauge can handle aprox 300 amps max for short time , less on hot days , CCA wire less

(Copper clad alloy)

remember if that thing arcs without a fuse ( even with one its still going to throw a huge spark before it blows a fuse ) its going to possibly catch the car on fire !!!! so use care !! tie it down etc

If it hit a metal fuel line instant fire , it will arc right thru the line like a welder

Do not pinch it or coil up the extra wire under carpets , get it set up the way you want and cut off the rest , never splice it back together its bad practice and creates a resistance

expect new AGM battery

And new high output terminals to match

That factory battery will be toast with a big amp

And those factory terminals suck balls and restrict battery options

Update the ground to engine and frame

0 ga to frame

4 gauge to alternator bracket bolt

At the least

take the plastic inner guard off from behind the front drivers wheel, or take out like 3 screws and fold it back a little. its a big black grommet with the bonnet release cable running through it. cant miss it

[r34unit]

ok and wheres the hole to pass through into the car and down to the fuse box?

[scythe]

failing that theres a grommet up behind the glovebox on the passenger side which is slightly easier to get to =)

Do not run cable across the car stay on the battery side , its bad practice and creates Resistance , plus turbo heat melts wires

And it would take another meter or more wire $$

At this point if you cant see the hole and how to run it , go see a pro ,every car has ten ways to get cable into the car , another choice is under the car but that requires a lot of safety considerations and more cash to protect the car and wire from damage

there is a good video on wire protection on the worlds highest scoring car audio comp truck shows the right way to run under a car when you have endless cash ( do not run under the car without watching how and following the same principal idea skylines have a lot of pinch points to avoid)

It passes thru piss easy its only fussy inside the car because 0 ga is so thick you have to make 100% sure its secure or it will pop up while driving

Or annoy you with a lump in the carpet !!

Thanks , but you dont need too do that even

but maybe they can find it that way ??

if not maybe paint it neon yellow and flashing leds! Serious its not hard to see

haha all good boys found it the gommet. the key point is to pull back the guard lining ! u cant see it other wise ! once i did that i run the cable in 15 mins !

and the last system i built i got a 145db with 2 12s running off 2.5k rms on music so i have a little experience with car audio !

cheers guys thanks for the help !!!!
