Stereo Wiring off the stock HU?

I'm installing a pioneer bass bullet Pro system (with the sub and sub amp off the street system) soon.

Cost about $1000 and about $250 for wiring, converters, etc.

Just to give you some background, Everything is wired up ( grounds connected, power ready to put onto battery, wires hidden under interior panels, RCAs run).

The only issue I'm facing now is which wires are speaker wires on the back of the HU?
I don't particularly want to change it, at least not for a few years because I like how simple it is, and it has my BT audio and handsfree, USB etc.

I plan on running all into Line converters into a 4ch amp then back up into the stock wires into my new speakers.

Any help or directions would be greatly appreciated, as I've searched the web lots of times so far, been quoted $200 by Mitsub for the workshop CD, told to put a battery between every two wires by jaycar, and a car audio shop told me check the door wires (which are same colour on each side).

wha!?!>?!
 
the battery between the 2 wires is meant to make a speaker make a noise to locate which speaker corresponds to which wire colour set bit of a ghetto technique


in my 100% honest opinion buy an ISO harness for it if you dont know what you are doing wiring wise

the ISO harness is consisted of 2 separate harnesses that plug and play head units, one goes from the factory head unit plug to an ISO plug end the other starts at the corresponding ISO end and will go to a plug that fits your head unit if you get the one to suit ur brand head unit
 
I'll see about a harness but i'll still need to know wiring colours due to using stock wiring to get power from my amp to the new speakers.

And to Cesario:
1. Went to mitsub dealer and they said they could sell me a workshop cd for $200
2. went and asked jaycar and they said to try the ghetto battery technique. proble is with that even, i don't know which wires in my two harnesses are for the speakers, at all.
3. xtreme car audio said on the phone to pop the door panel and check but they were same on the left and right, which i know doesnt mean running off one set of wires because i can fade and balance it through the HU.
 
Your aftermarket HU should have a wiring diagram in the manual indicating what wires go to which speakers for example Blue- Front Right , so on so on i suggest disconnecting your battery from the negative terminal whilst doing this and get a double a battery and short it out over the cables you will get a static/crackling sound over the speaker and then you can go ahead and connect it, I would suggest soldering and heatshrinking your connections or using crimp lugs for best connections :)
 
So I just went through my phone and found a picture which has all the wires listed. It's from before I got the car a month ago...what are the odds!

And btw I'm keeping the stock hu, just putting speakers amps and subs. For now at least.

as a standard, pos power will be a hot colour either red or red with yellow stripe or sometimes but not often a burgundy dark red, and ground will be a black, that gets ur amp etc sorted

as for speakers, when testing with the battery test, there will be 2 wires of each colour so say blue for example, 2 blue wires, each will have a mostly blue insulation with a coloured stripe
the 2 blue wires (or wires of same colour with different colour stripes) are your speaker wires for 1 speaker

these wires can be green, yellow, pruple, orange, white etc etc with different strip colour

for example purposes only:
front left = purple with white stripe wire, and purple with blue stripe wire
front right = green with yellow stripe, and green with red stripe
rear left= white with red stripe, and white with blue stripe
rear right= yellow with blue stripe, and yellow with green stripe
 
So I've gotten everything installed. sounds crystal clear and is louder than stock.

Back of stock speakers say they're 15 watt, so I suppose i'm pumping and additional 45-335w through them now...

One issue I'm having is that when i turn the volume up to a certain level or higher, the speakers cut out and all I hear is bass. This is with the stock HU, due to money constraints at the moment.

I have line converters on the stock wires which lead down to my amp, then wiring going through the other side connecting back to stock wires behind the hu.

HU-->LOC's-->RCA-->AMP-->my Wires-->Stock Speaker Wires--->Pioneer speakers
So basically cut the stock wires and added plugs, so RCAs take all signal, amplify then goes back in stock wires to speaker mount positions.

Off the amp http://www.pioneer.com.au/au/products/archive/GM-D9500F/page.html there are two sets of RCA inputs and one set of output, which i connected to my sub amp. Apparently, input A is routed through but before amplified, it is also routed to the OUTPUT A ports...

It came with rca plugs which i can just connect to wires straight up and plug into the amp.

Should I use those? Does anyone have a clue how to fix this? please :( ?

p.s. COuld the tweeters be causing it to cut out? the pioneer components in the front just continue on the wire to the tweeter, but im thinking the stock wires which were in the mount might do the same thing anyway...
 
If anything sounds to me like you are over-driving the amp and causing it to cut out.

If you have components you should run a cable from the amp to the crossovers and then from the cross overs to the speakers and amp. I would recommend locating these under the front seats and running two new wires into the door for the speakers and tweeter. You cant connect new tweeters upto the same factory tweeter wiring if thats what you've done.

I suggest drawing a diagram to show what you've done though because I can't quite understand what you are trying to say you've done....
 
Sorry for the late reply. Basically got a new pioneer avh-x5550bt and now I can pump the music to deafening levels. The line out converters I had on the stock hu wouldn't put out enough power so the signal to the speakers would cut out at a certain volume level.
With the new hu, maintained my swc except with the adapter I can't seem to get the bt phone buttons to work properly :(

I don't mind though its pretty awesome to hear
 
I have a MY13 VRX Lancer, I attempted to install a aftermarket dvd headunit. I used a mito02 harness. The screen was working but there was no sound. I want to keep my stock SUB and AMP for the moment. Has anyone attempted to swap the units before in the 2013 vrx Lancer?
 
Unless things have changed over the years the amp is for both the speakers and the sub, all of which are pretty gutless though. I was under the impression the amp works by feeding 2 channels of line level audio to the amp and then all the mixing is controlled over CAN-bus. Personally I opted to instead at the time rip all of the RF crap out of my car rather than try muck around integrating it.

I don’t think the Axxess MITO-02 was ever used much by anyone here, but the best port of call in anyway would be to contact the manufacturer about it.
 
Ive noticed the best bet is to just replace everything from the wiring to the amp and sub and headunit! its alot safer I think.. I wish it wasnt so much trouble to replace... the stock headunit is completly crap! Ive had so much trouble with it. Its been replaced once before and even the new one still messes up! Im getting it replaced again with another stock one by mitsubishi. if it stuffs up again, I will be saving to get everything replaced.
