I would like to know if i can keep the stock in dash 6 cd changer and somehow add another amp or replace one of them in order to get better sound with the factory deck. If possible is there wire harnesses i could use in order not to cut too many wires. i was hoping to install 2 10" subs inthe car with a 800 w amp. THANKS IN ADVANCE FOR ANY HELP

You can use a line out converter to keep the OEM deck and add an amp to power better speakers & subs.

WHERE CAN I GET A LINE OUT CONVERTER AND WHERE WOULD I TIE IT INTO? THANKS

The LOC ties into your speaker wires and this converts the speaker output into a RCA signal. You can get it at any electronics shop or automotive store that has a car audio section.

DO THE SPEAKERS HAVE TO BE DISCONNECTED IN ORDER TO USE LINE OUT CONVERTER FROM THE STEREO? THANKS

No. The signal that you are tapping into has not hit the factory amps yet if you run it between the HU and the 1st factory amp. That signal then gets split between the 1st amp, and whatever amp you install, then amplified. So you can keep the original speakers, and add your own subs. I have an '02 stang that I completely ripped apart and installed my own system. The Mach460 was good, but no where close to what I have now! Here's some links to help you with the system (location, function, etc...)

Got a question about this, I know now where the two amps are in the back (have a 99 convertible). What I need to know are the following: I do split the signal before the hit these amps, correct? And what color are the wires that I am spliting off of (+/-)?

Well it depends what level signal is going to your converter. If the converter is a hi-level (speaker-level) to low-level RCA converter, which it probably is, then you'll tap in to the wires AFTER they've gone to the amplifier. In other words, between the amp and the speakers. I forgot the exact coloring of the wires but I know you can find it in one of these pdf files. https://www.flemworld.com/95/MachSch/RadioDiagrams.ZIP I used this site a long time ago for an install and the diagrams were a lifesaver.

Let me get this straight. I will split the signal after the wires have gone into the amp with the LOC? Didn't the guy above you say before? I thought I would want to split it before so I can run it to the amp I will be installing which will power my 2 subs. As for the wire coloring, I think I can figure that out tomorrow on my own, I just briefly glanced at it this evening.

Like esmith69 said, it depends on what type of converter you are using.
If you want RCA input into the amp, you would want a Line Out Converter (converts High Level signal to Low Level signal used by RCA's) like this one LOC
This gets installed between the OEM amp and speakers like esmith69 said.
What I was referring to before was an OEM converter that allows you to match the gain of the HU output to the input level required by High Level input amps. This one gets installed between the HU and the amp. It's usually used when installing an aftermarket HU but keeping the factory amps. I have seen it used before though when keeping the factory HU and replacing the factory amps with different High Level input amps.
In your case, I would suggest using the Line Out Converter ------------- Squirrel

Alright gotcha now.. so I will split this off the amp that goes to the "super speakers" correct?
Basically, as I understand it, I will be running a IOC from the amp in the back that goes to the "super speakers" to my new amp which will power my subs.
Just want to make sure this is all correct so I don't fry anything and have to spend more money than necessary.
Still am sorta confused about the wiring diagram, but it doesn't really make sense to ask questions about it until I can get a better look at the amps later on today.
Thanks for all your help thus far.

After a long time of looking for something like this in the beginning (about 9 months ago) I gave up and redid the entire stereo. Now there's all kinds of things out there about modifying the Mach460! Here's a good "How to" article on adding the LOC's to a Mach460 system... Mach460
As far as wires go, you would splice the LOC's into the 2 black wires with white stripes and the 2 black wires with green stripes. The wires with the white stripes are the negative wires (obviously you would splice 1 of each for each LOC!). ------------- Squirrel

ok i cant stand by and watch this any longer.
the mach 460 for 2001 and up. there are two amps in the rear... when facing the front of the trunk from behind you will have a plug with 3 wires. one wire is left one wire is right one wire(center) is remote.
on the other side of the amp facing the rear of the trunk you will have 8 wires GREEN/ black purple and pinkish/red. this is power and grounds. you will also have in the upper (right) section of the same plug with 2 wires included in the 8 that are output signal. blk/wht grn/blk (pos-negative). the amps put out a mono signal to both rear speakers or front speakers whichever amp we are dealing with which is low frequency crossedover buy the mach 460 headunit itself.
so what you have is 4 (front/rear) speakers powered high level full range. then 4 (front/rear subs)speakers powered low level off the deck also. all internally crossedover.
behind the HU you have the main harness 14 or 16 pin depends on if aftermarket harness is used. and also the amp harness.amp harness consist of 8 pins. two are amp grounds two are amp turn ons. two are pos two ar neg signal.
when making connections to an aftermarket HU you need a metra amplifier integrator harness for THIS SPECIFIC MODEL 2001 MUSTANG anything else will not work.the mach 460 changed its amplifier plug in 2001 and uses 1 less amplifier (2000 lower used a 3rd amp in front under the radio itself)its a direct plugin and partsexpress sells it. im at work now part number unknown.
buy using one power wire, one ground, and the remote turn on wire off either the amps themselves or remote from the car (you might want to use the remote from the car 12v seeing fords remote wires 4v puts out less voltage) you shall get your power.......
the speaker wires are self explanitory above. before the amp they are unamplified after the amp they are amplified.
thats all there is to the factory 2001 up mach 460 indash 6 changer. i can post wire diagrams for the amps and head unit configurations if necessary.
my setup in this vehicle consists of 2 bazooka el8a-hp amplified subs with factory everything else.power ground ran off the rear right amp. signal wires ran after amplification off both amps (the subs are dual coiled). seeing it is low level, i went with after amplification so it will produce a useable signal for my high level inputs of the subs.
alot of people write about how hard this system is to work on and actually if you get familiar with the wires and how it works then its a piece of cake. i hope this helps

I'll double check my wiring diagrams from Ford, but I could swear that the 02's went back to 3 amps. ------------- Squirrel

not that i know of...i dont think ford has gone back with the 3 amp design....the sub amps power 2 5x7 speakers per side in a mono configuration. i take it they are prolly 8 ohm each to give the amps a 4 ohm load.i wouldnt think that an aftermarket ford amp would play at 2 ohms. an the 4 highs are powered right from the HU itself.
the 3rd amp in the 99 below powered the high speakers. which i find was a better setup.

That would explain it... When I redid my system I used a harness to tap power, speaker leads (which I thought were going to the front amp), etc... but ran my new components from RCA. The only thing left speaker wise from the factory was the front 2 tweeters, which I thought was being run from the 3rd amp (signal being sent through the harness). I remember seeing something in the area that the amp would have been that wires from the factory HU were running to and out of, but it may not have been an amp. I have to pull my HU again to find a way to kill the vibration I'm getting, and I'll take a look to see if I was just imagining things (which has been known to happen!) I'll let you know if I find anything in the '02 schematics (had to special order them last year since Ford apparently doesn't install the mach460/1000 themselves) ------------- Squirrel
