If youre looking to upgrade the speakers just forget it. I know this is going to be hard to swallow. But you would be better off just scrapping the entire system and getting a new deck, 4 channel amp with 2 sets of component speakers, and a subwoofer system. Heres my reasoning.

Ford/Mach Audio made the mach 460 sound system for the user to listen to at moderate volumes. Throughout the years they used essentially the same 1995 speaker technology. So the internal equalizer is always trying to compensate for the speakers imperfections by overloading the signal with bass and treble. Sure this sounds decent with the factory speakers at normal volumes, but turn it up loud and youll know what I mean. By adding aftermarket speakers you will only be making the problem worse.

Now my second reason is because of how messed up ford wired the system. Your system has 3 amplifiers. One operates the tweeters, and the others operate the woofers. If you were to replace the deck directly, you would only hear the sound through the tweeters. (A special wiring harness can take care of that). But then all your quality gained through a new deck is lost through the poor amps.

So you say: "alright, i will just replace the deck and the speakers, and use all the factory wiring" WELL then, best of luck to you because the amps will melt. Each tweeter and woofer is rated at 6 ohms. At the crossover (separates which frequencies are sent to the woofer or tweeter) the final impedance is rated at 3 ohms because of the parallel wiring in the crossover. Now most aftermarket component crossovers are wired in series with 2 ohm drivers to equal a 4 ohm final impedance. But if you are directly placing these aftermarket drivers into the factory wiring, then you will be giving the amp a 1 ohm load. Which is highly unstable and unsafe for the factory amps.

So lets say you want to use the aftermarket crossover to bypass the whole unstable load situation. But thats not possible because remember in the mach system, the signals coming to the woofer and tweeter are coming from separate sources, which makes using an aftermarket crossover impossible.

So ultimately. For substantially better sound, you should go and buy yourself an entirely new system. Buy a 6 channel deck, have 2 RCA's go to a 4 channel amp. Have the other 2 go to a mono channel subwoofer amp. Re-wire your new component speakers from the amp (since the signal that will be going to the speakers from your new amp will be coming from your trunk, re wiring is fairly easy because youre not working in the dash) Then wire up your subwoofers, and set your highpass/lowpass settings on the headunit. You will have an incredible sounding system, and for a lot less hassle than dealing with the factory mach system. But thats just me.

thanks I am very familar with building systems my issue is that the cheap front door tweeters are bad so I either have to fabricate a tweeter to fit in its' place or find something that might fight directly bacuse you cannot just scrap those pods or you will have a nice hole in the top of the door card

I bought a nice pioneer deck, and not that I know TOO much about sound systems, I put the deck in and adjusted the audio on the system via the new deck and it sounds great, bass and all. This is via the Mach 460 audio system just with a different deck. I'd consider upgrading the rest if it wasn't already loud enough. (Yes, got the wiring harness too)

Wow, you're lucky, I've installed systems in my other cars and the ford wiring harness I got only played the sound through the tweeters. Plus I already had a 4 channel amp laying around so I just invested in some nice components and built it. Plus I have a converible, so when the top would go down the soundstage would go with it. So it was time to upgrade to some more adjustable directional components anyways haha.

Going with aftermarket

Hey I have an 01 Bullitt with the Mach 460 and I am going with what was mentioned above about the complete aftermarket system. The only problem is that I can't figure out which speakers will fit. I am in New York and My car is home in Missouri. I only get about 10 days of leave for Christmas so I'm hoping to have the speakers waiting at my house when I return because I won't have enough time to install them if I have to order them after I come home. Anyone know the speaker sizes? Thanks

The main speakers, I'm pretty sure, are 5"x7". Not 100% though; the few times I've had door and interior panels off I don't recall actually measuring them.
