How do you Install an Amp Wiring Kit?

[VS Black Beast 9C1]

I just bought myself a 1200 Watt 5 channel Cadence Amp and basically I just gota find out how to install all the wiring kit in my VS Commodore. I've never seen it done b4 but all I know is the you gota run the power and ground cables along the right side and the RCAs along the left.
If anyone could be bothered writing an essay then go ahead coz the more detail u give the easier its gona be for me.

I wana know exactly wat to do to run the RCAs from the head unit to the boot (such as wat u have to take out and wat screws to undo etc, pretty much everything). Then the hardest part for me is gona be the firewall, how do i get the power cable from the boot to the battery?

Last of all is connecting all the speakers to the amp. The rear shouldnt be too hard but if anyone knows the easiest way to connect the front door speakers then that will be really helpful.

THanks for any help and detail you can give.

well for a beginner it will take a fair while to do all the wiring properly, what speaker are in your front doors? i wouldnt bother amp'ing stock speakers. but you'll need to rip the door trims off so u can wire them to the amp, you can wire them straight to the stock wires but its dodgy way around it.

The main power cable, theres 2 places you can run them through the firewall, but if auto, the clutch grommit. otherwise theres another grommit next to the brake booster. You will need to remove the headunit to run RCA's and turn-on wire. remove Kick panels, rear seat etc to run all cables up the back. Ground cable only has to earth on the clean metallic point on the body, like seat/seatbelt bolts just make sure you scrape any paint off for a clean contact.

just keep your RCA's and Power cables away from each other and you shouldnt have trouble with interference, make sure all your crimps and/or solder are strong and insulate all wire joins with heatshrink or electrical tape.

if you have anymore questions just ask.

have fun.

Well said vn6pwr

[garfa]

mate, do a search. theres a heap of info around.

looks like im in same boat, cept i have a vs wagon. gonna attempt it 2morra, hopfully it will be alright. ive alrdy had all the door trims off and that to check the size of thw wholes, so thats easy. i was think of tapin the new wire to the old speaker wire and pulling it through, sounds easier to me and less work.

Thanks for that description but to answer your question, no i dont have stock speakers. I would be a stupid kid if i was to hook up an amp to stock speakers lol.
So wat i have done previously in my car is put and new head deck in, new front door speakers, and new rear speakers. So door trim, rear seat removal and parcel shelf removal is nothing hard for me, i watched my cousin take my head unit out so thats nothing too hard.

Just a couple of questions....
1. where exactly is the clutch gromit located and wats gota be done to get to it (and through it)?

2. Also im guessing I have to run all the wires underneath the doorsills BUT for the right-front door speaker will it be safe to route the speaker cable along with the power cable?

3. Also when trying to get the speaker cable into the door wat is the easiest way of getting it through that black hose that carries all the wires through?

One last question...
4. When routing the RCAs to the head unit, once you get the cable past the kick panels, would you just run the rest of it underneath the carpet until it reachs the stereo?

Thanks again for all ur help guys.

i did some of my wiring for my amp today. got the power cable through the gromit and into the back of the wagon. to get to the gromit u remove the panel under the steerin wheel(were all the fuses r). you can sorta see it. open ur bonet to get a look at it from the other angle to. its between 2 bolts. to get through it i drilled a whole in it with extension drills, the attatched my power cable to a stiff piece of wire with tape. then feed the stiff wire through first and pull the power through. saves alot of time. when i was pulling my wire through though the whole wasnt quit big enough and i pulled the gromit out. to save puttin the gromit back in i just used a bit of foam with a whole in it to plug the hole. dosent take to long.

i then took the rest of the day trying to access the stock tweeters without success. if any1 knows how to do this in a vs it would be great if you could tell me.

Dude u didnt even have to bother drilling a hole and using a stiff wire to get it through the clutch gromit. I just did mine today and I was just able to pop off the gromit using enough force, alot easier than drilling a hole and then after u just gota make a hole through the insulation. I seriously thought that getting through the firewall was the hard part, it turned out to be real easy.

I think now i have reached the hardest part and I truly am stuck for ideas. I am upto replacing the speaker cables in the front doors and I URGENTLY need some help. I will try to explain my best but Im sure most ppl will know wat Im on about. Im talking about that small rubber hose or tube that carries the wiring from inside the cabin to inside the front doors. It carries all the wires inside of it and its pretty much the only way to get my speaker cable from the cabin to the door. Im not gonna do no cheap job and drill a hole so if there is an easier way to get speaker cable through that stupid rubber hose then please tell me coz its doing my head it and I cant see any other holes in the door to put wire through.

Thanks in advance.

Never had to it before, but i think the easiest way would be to pull the tube out from the door side, get your speaker wire and feed it into the door. now get a small piece of wire a secure it to the end of the speaker wire and feed into through the tube into the cabin.

chop QC's off the stock speaker wire in the door (you can just use the stock stuff but people seem to hate it) and tie on the new wire and just pul it through.
or you can tie on the speaker wire to a bent coat hanger and push it through the boot.

I didnt think you could tie the new wire to the stock wire and pull it through, as its part of the whole door loom. I think the second idea is much better

also whilst im here, does anyone know on a VR Berlina, I was installing some splits in yesterday and the speaker connector in the cabin (behind air con vent) has 4 wires which then go into 2 before they go into the door? eg. FR has 2x light green and 2x dark green on the same pin, i was thinking they must be for a tweeter somewhere but there was none.....

also whats the big module behind the drivers side kick panel? looks like another ECU

I made sure i bought 10 metre long RCA's just to be safe (i got 2 sets because i am running 2 amps 1 amp for sub and 1 amp for in cabin speakers) to use with my 3RCA output headunit. I basically took out the centre console, ALL the radio surround and the glovebox lid, ran my RCA's from the back of my headunit (which is a pain in the rear as there is a bee's dick worth of space behind the headunit once it sits in snug) behind the back of the glovebox down under my ECU and into the entrance sills all the way to the rear out of the entrance sills up under my rear seats and through the hole up in the corner under the back of the seat up in the corner (there is a factory cut hole on each side up to the left of the left back headrest and up on the right of the back right headrest) and into my amp which is mounted in the boot behind the seats. Try and get 10 metre long RCA's, it's always better to have extra length rather than not enough length.

It's not a crossover from a previous set of splits the person who owned your car before you had installed is it?

no it was definately factory. First VR i'v done so i cant see why the extra 2 on each side were there for, the only reason it thought was maybe they have left wiring provision for tweeter in later/higher models.

I was able to get the speaker cables into both doors today. I didnt use a wire to feed it through (never had the idea) so instead i kinda did it my own way and just used a scalpal and i actually cut the thickest part of the rubber boot off (the thick part that seals the hole to the cabin) even though i had to be careful not to cut any of the wiring loom inside of it. Basically it gave me enough room to feed my speaker cable though without a problem....I guess i just didnt have the patience LOL.

As for the RCA cables I have 5m lengths and thats more than enough but as one of you were saying there isnt much room at all behind the head unit. I struggled pushing mine back in. But what I did was I put 3 RCA pairs in even though my head unit only allows 2 pairs (basically its there for the future for weneva i decide to upgrade to a better HU).
As for the RCAs going from the cabin into the boot... i used those factory drilled holes for speaker wire but for the RCA I just put it through that big opening so then it could go straight under the carper. If i put it through the holes then u would still see it.

Btw does anyone have any good ideas for mounting an amp, I have read that u can place a wooden board under the carpet and mount it to that instead of the car body. I didnt want to sacrifice too much boot space for an amp so im thinking of just placing it onto that big hump (the raised section) toward the back of the boot just behind the seats. Im just not sure if thats a good spot to mount it especially since i dont have a sub just yet. Any idea would be great and keep in mind i my amp is 1200watts so its probably has the biggest dimenions.

vnv6: most commodores you can just pull it through. no probs.
as for the extra wores draw a dcircut dia or grab a dimm. there were only ever i tweeter and one woofer in commodores. never 3 ways in the front.

also you can get 10 meter rca's and then pull off all your door sills or just run the 5 meter long rca's along the tranny tunnel and under the seat into the boot. and you dont really have to remove anything, just run them under .5 meters of carpet!!!




also if you have cut the boot then there is A STRONG POSSIBILITY of water getting in.

Sorry didnt mean 3 ways. will let the picture do the talking its too hard to explain. The only thing is there was no tweeter present anywhere, so i just crimped onto both when wiring the crossovers up because i didnt know what wire was from the headunit.



any ideas where to second wire traces back too?

EDIT: also cant see how you could pull the wires through that loom?

[garfa]

just pull the wores through the loom with great force. theres are a heap of strands so any that break will be fine!
still have NFI what your on about vnv6pwr.......

should have taken a pic, there were 2x grey wires and 2x brown wires going into the plug (same on both sides). obviously only one of each colour come out of the headunit so im just wondering why they double up on the plug like shown in the diagram. If you still have no idea dont worry.

.

I was also wondering that to!
Will it interfere like it will with the RCA's?

Also how would you put the remote wire to 2 amplifiers as i have two. one for my sub one for my speakers.
would you just split it or crimp to wires??

Because that goes to my headunit.

power cables and speaker wires should be ok together, but not power cables and RCA's. the reason for this is because interference can be picked up by the RCA's and amplified which results in a whining sound through your speakers.

as for the remote wire you can do whatever as long as both amps are are connected to it.

[Heffer_Slayer]

thanks for the quick reply mate. cleared that up.

also my amp has a capictor or fuse or something.
I assume it goes on the power cable.

is there a correct spot to put the fuse in or can it go anywhere?

Obviously it should be easily accessible..

but near the amp? near the battery?

does it matter?


Also i have a 4chan amp for my speakers, should i replace the stock speaker wiring??

[azzfox]

the fuse should be as close to the battery as possible (within 30cm).

if your going to be running an amp for your speakers you will have to use new speaker wire because how could you use the stock wires? either way I would use new wire.

As in i could just crimp on extra wire which would save me going behind the doors but yer your right new wire would probably just be the better option.

I have to packs of wire one is 16 gauge the other is 12 i think.

Is gauge really important for speaker wire?? Mainly when amping?

Are there any special voltage requirements with all this or is it just simply straight from the battery.

EDIT: Btw my headunit has sub control and high pass filters and low pass filters. Should i let the amps or headunit control all that?
