1993 Premium sound stereo into 87-92 Mustang : Install thread

[Mustang5L5]

The CD module inside can be replaced separately. If you take the top cover off, you’ll see the CD module on top. Held in place by 4 torx screws and one ribbon cable.

There’s a part number on the module. F2DF- I think. Hop on eBay and search that number and you might find the unit. Problem is a lot of the ones for sale are used and questionable.

Often times, the gears/motor stick due to years of inactivity. They can sometimes be unstuck and lubricated up. They can also strip. There’s a seller on eBay named “dlsvc46” who is a former radio tech that sells a lot of parts on eBay. Has helped me source a lot of these obscure parts. He might have a small gear or so if you find that to be the cause.

Typically what I’ve done in the past is buy another CD player from something else with a working player. If the cd works I’ll just swap the unit. Most of my radio “repairs” these days are just swapping parts around to make one good radio from 2-3 bad ones. Unfortunately with components hard to find, that’s all one can mostly do.

I have the premium in my 1993 mustang. The amp appears to be bad...erratic sound. Want to remove the amp and just use the radio without the amp. How do I connect the speakers to the radio when I removed the amp?

Like your information, has been a great help. Have pulled the radio out and disconnected the antenna, power, and speaker plugs. I have a jumper lead I bought for the amp bypass. Just do not know how to install the amp bypass. The amp bypass has a wide plug and narrower black plug connected by colored speaker wires, ie two purple wires, etc for each speaker.

thanks,
Mike

Hi Mike. Unfortunately you can’t. The head unit and radio are designed to be used together as the radio only outputs line level audio meaning the amp has to boost the signal to power the speakers. If you wired the radio up alone you’d barely hear it.

You need to pull the amp and harness and locate a non-premium head unit. You could either go back to the 87-92 non-premium type or find a 1993 non-premium radio.

Those 1993 specific amps still pop up on eBay from time to time. About $75-150 when they do. Unfortunately I see non on eBay now

A non-premium head unit in good working condition will likely cost you more than that.

I thought Metra had an adapter to utilize the head unit but with an aftermarket amp?

You can use a Metra 70-5510 or a 70-5511 to integrate an aftermarket head unit with the factory amp for 1993 premium and 94-00 Mach 460 Mustangs.

I'm not aware of any metra kits to use OE head unit with aftermarket amp. You might be able to hack up the OE harness and wire in the line outs to an aftermarket amp, but I can't speak to that as i've never looked into it.

I have a premium amp for 1993 that I could let go of.

 

[Mustang5L5]

I have always wanted to try a 1994-00 non-mach amp with the 93 premium setup. There is a non-mach 460 version that I think it would work. I believe it is full-range. I'd have to get my hands on one first to try and there are a few cheap ones on ebay. I think the connector is different however. I have a few dead 93 amps i could desolder the connector to.


94-00 non-mach premium amp would power four speakers full-range. 94-00 mach amp powers 4 speakers high range only and has output to the two main "supersound" amps.



Of course you could get creative with this as the 93 head units work directly with the 94-00 Mach 460 sound system. That means you can swap out the underseat amp with a 94-00 Mach tweeter amp, and this would power 4 high-frequency speakers. You could then use that amp to control the two mach "supersound" amps to control the 4 low frequency speakers. Of course now you need to figure out where to put 8 speakers and 2 more amps.

I mean you really gotta love the OE system to go that far...



EDIT: Here's a 94+ non-Mach amp. I think the amp line-in connector differs from the fox so this would be a challenge. This is unverified so don't anyone buy one and think it's plug-and-play. 94-00 MACH amps will have 3 connectors. One is the output to the 2 additional amps.

Mike, what is the name of the book you got this page from? I want to buy a copy but my searching has come up fruitless. Thanks!

 

[Mustang5L5]

It's out of a radio repair manual from Sony for these radios. I snagged it off Ebay a few years back. I'll see if i can get a shot of the cover but i've only seen this one. I'd PDF it but it's massive.

Here are the difference between the 1993+ Premium and non-premium radios that came in the Mustang and other Fords.


PREMIUM SOUND

This style radio was manufactured in partnership with Sony. These do not have any sort of internal amplification so they rely on external amps.

This is the back of the premium sound head unit. Note that one plug looks familar to the basic 87-92 wiring, but the other 3 plugs are different.

Plug on top is for the CD-change or SLAVE CD hookup. It's a 6-pin plug Yes, the 1993+ familr of radios will support a slave cd player (like 94-00 Mach 460) or the Sony 10-disk CD changer used in the 1991-1992 Lincoln Mark 7 (which is plug and play)

Middle plug is the AMP Line-out plug. it's an 8 pin plug, and basically thr blue wire from the 1993 amp harness connects here.

Bottom plug is barely visible, but is the steering wheel controls plug that came in some Taurus's and Explorers. WOuld be cool to get this operating, but dont see how.

IMPORTANT! Notice the black shorting plug on the top of the unit? This NEEDS to plug into the 6-pin connector on top if you are NOT running a Slave CD player or CD changer. If you do not use the shorting plug, you may have volume issues or no sound at all. SO make sure you have this!

Part number for this shorting plug/jumper is F2DF-14A464-AA

Edit: I’ve recently gotten my hands on the internal schematics for these radios and found that 93 mustang specific radios have the jumper internally soldered. No external plug required for F3ZF- radios only. All others need the shorting plug.

Pinout diagram. The shorting plug would connect input L to output L and input R to output R.

NON-Premium

These are known as M100 radios. They have an internal amplifier

This is your standard wiring hookup of most fords in the late 80's and early 90's. Ford changed the head unit design around 1993, but carried over the 87-92 style of wiring. SO, that means that if you have an 87-92 Mustang (with or without amp) and want the newer style head units, but do not want to switch over to the 1993 style amp and amp harness, you need to seek out a NON-premium head unit from various 1992-2000 Ford's. I would double check the wiring as some of the 93+ non-premium units carry two grounds in the wiring harness. The 2nd ground is for the illumination and you will need to add it if you want the radio to light up at night. I've only briefly explorered this, so i willl leave it up to you to discover. However...it's an option

This is an old but helpful thread, my 1993 amp gets constant power to the amp with the key out and with the factory head unit out , is this normal? Appears to be a White and pink

Yes, that is normal. In 1993, the amp has it's own power wire that is not connected to the head unit at all.

White/Pink wire runs direct to fuse #17 and is a 20A fuse. It is hot at all times

Thanks!!! Yep just located that fuse the manual left blank. Again I appreciate it

Ok I’m checking for some parasitic draw. The amp appears to have a ground and power at all times with the head unit removed and key off. So is there no trigger for the amplifier at all on the premium sound systems? Looking at the wiring diagrams it appears to get power/hround at all times. Thanks

 

[Mustang5L5]

Pin 16 on the amp, which connects to the radio is a “radio on” trigger meant to power up the amp.

It receives constant power at all time, but is not on until the radio commands it on.

 

[Charlie1]

I’ve got to check pin 16, that appears to be an additional ground. is there a harness that will bypass the factory amp utilizing the “factory” head unit? I’m not sure how loud it will be with just the head unit. I’ve come across several post with different part numbers online but most are using a aftermarket head unit. Thanks again!!!

 

[Mustang5L5]

It can be done but you would need to change to a non-premium head unit. That won’t be easy to find.

The original head unit is meant to work with the amp.

If you go aftermarket you bypass the amps as it’s only 80watt and most aftermarket head units output that with much better sound quality.
