Ok I was stumbling around the internet trying to see if my Shaker in my 05 was satellite ready, it's not { if you read this posting before, you will know that I had some bad things to say about the shaker, I apologize for my snide comments, I only want to help out if this is something you would like to do }, but in my looking I came across a thread on the Mustang Forums
http://www.mustangforums.com/m_1490837/ ... ey_/tm.htm that talked about how much better sound you get out if the speaker system and subs that are already in the car if you just upgrade the head unit to a hi end after market head unit like Alpine, Kenwood or my favorite Pioneer, any of the good ones will give you the results that I mentioned. I did this and wow what a difference, the only problem that I found to the hole thing is that all of the aftermarket units use a 12 Volt + turn on lead for the amps, the shaker uses a 5 V + turn on, this causes a loud pop when you start the car or turn on the stereo unit, some folks just deal with it, but my fear is that if you continue to feed 12 v into something made to take 5 v that your going to burn it out eventually, so I saw on the Mustang Forums thread that you can build a 5 volt converter with parts from radio shack, if you read that thread you will see what they suggest and you may want to go that way, but, I have a simple fix for the 12V/5V turn on problem, after reading the whole Mustang Forums posting
I went to Radio Shack and ask for the things I needed and they looked at me as if I was
Speaking another language or something, So I came up with something that worked
Perfectly, if you are a little afraid of soldering things together and finding heatsinks and all of that, Just go buy a cell phone car charger that is for a 4.5 Volt DC phone and do this.
Take the cigarette lighter plug of the phone charger apart; this is normally 1 or 2 phillips screws,
Hook up the 12 V + amp turn on from the head unit to the 12 V + wire that feeds the
Phone charger {this will be the wire that is attached to the center post of the adapter,
Go ahead and cut this wire off of the post as you will not use the post and you will want to remove it from the adapter so it cant cause a short later} Hook the Ground – wire of the adapter {this is the wire that is attached to the side contact of the lighter adapter, go ahead and cut this wire off of the side contact and remove the side contact, again because you don’t want it to cause a short later as well} to the Ground wire of the head unit, you must use both of these wires because you will only be using 4.5V + of the 12V + that the head unit provides, so the other 7.5 volts have to be siphoned off and you will need a ground to take care of that, without going in detail of how all that works. Now you are going to cut off the plug that would have gone to the phone, at this point you will have 2 wires, and they will be 4.5 Volts + and -, you only have 1 turn on wire that you need to hook up to the harness that plugs into the cars amp and this will be the + or Positive, the – or negative wire you will want to tape up as this wire will not be used, make sure you have taped or in some other way insulated all of you wires so you don’t get any shorts, ok now put the lighter adapter back together without the center and side contacts that you removed earlier, the wires that you hooked up to the 12 Volt side of the adapter can be routed threw the hole that used to hold the center post [ convenient ha ] I also taped mine up to keep the wires from moving around during the rest of my installation, and it works perfect, I get no popping on turn on and the amp works perfectly. The great thing about using this method is that you can get the adapter just about anywhere, and it has a built in heatsink already in the adapter, and there’s no soldering unless you want to solder the wires as some folks do. I have had my Pioneer in the Stang about 6 months now and the sound just blows the shaker away, So if this sounds like the solution your looking for, pick up your favorite brand, for me its Pioneer but any top of the line head unit will make all the difference in the world.
I hope this helps, and if you have any questions just ask, myself or someone else will be glad to help
