If you call Crutchfield they will walk you through every part you will need to replace your head unit.

If you are just doing the headunit and nothing else, its a direct swap with the correct wiring harness.

I bought a Clarion CX-501 from them for $200 and they threw in the adaptor and mounting bracket I needed at no cost.

Crutchfield sells the harness it plugs right in I did mine put after market radio in and it works fine its only like $ 20.00 but you just plug it in its easy

Im sorry, i didn't even think about my harness. Yeah i have the harness from crutchfield. I just got a new kenwood deck, i think its a kdc-x595. I picked it up friday, put it in when i got home. It is AMAZING. i love it. It has 3 preamp outputs. Im borrowing a buddys competition 12 and mtx thunder amp and i tell you what, it about blows my windows out. My only problem is it wont fit in the trunk. So thats the only bad thing

OK, I have been to many forums trying to get help installing a new Radio (Head Unit) in my 99 Mustang GT with a Mach 460 system. I got alot of insite but no real help. SO, this is all you have to do. You all had me thinking I was gonna need Low pass adaptors, special harnesses, etc. At my first attempt to install my new Kenwood kdc-BT948HD everything went smooth until I tried to get audio. Well, that is when I turned to the forums. I orders a special cable adaptor, bought a low pass filter along with bass filters for tweets, the whole nine yards...nothing got me sound. Well, I mentioned it to a buddy of mine and he had the same problem, but what it came down to was ONE STUPID WIRE. The Blue/White wire. I used Metra 70-5511 kit, wired it all according to the book, but without that STUPID Blue/White wire..nothing. Once I connected the Blue/White I was rockin out. The Mach 460 has never sounded so good. LOUD, clear, crisp. Now I can enjoy my music and actually hear it over the low rumble of my 'stangs side pipes.
Hope this saves someone countless hours, and at least $60 bucks in useless low pass adaptors and the ultimate $60+ install charge from someone that installs this stuff or a living. Or maybe I just gave you a laugh, either way my system is now 21st Century worthy.

That blue/white wire is a remote wire that sends signal to your amps to turn on

Okay, so I finished installing my new head unit, had two adapters in the harness kit, one for the big power, switch, ground, speaker plug, and the other is the RCA and amp signal, should I be plugging the RCA plugs into rear out, or sub out? Also, the main plug has a 12v amp signal as well as a amp ground wire, on the aftermarket head unit harness what should I connect these adapter harness wires to? The lower speakers in the rear I'm not sure are working and think this might be the issue but this mustang stereo set up is so weird I'm kinda lost. I'll get some pics soon

quick question for you guys....
I have a 400 watt amp I got from walmart for like $55, pretty cheap but it works.
and my subwoofers are 150 RMS (300 max)
my amp is turned half way up, but my bass boost is at +12db on my amp.

Am I underpowering my subs even with bass boost on???

what I was thinking was 400 watt amp turned half way is 200, so 100 to each, and they can handle 150 each, so could I turn it up even more? or does the bass boost make up for that?
