i have a 2002 gt with the mach 460 system. i have a questiona bout the rear speakers. how many watts are running to them, from the stock h/u, how many watts can they handle, how powerful are the amps that power the 6x9's, and if some aftermarket speakers would sound better. thanks
The rear speakers consist of two 6x8's and two 2 1/2 inch mid ranges.
The mid ranges are powered by the head unit, and receive 15W RMS each. They can handle 25W max, i believe.
The 6x8's are powered by a separate subwoofer amp in the rear deck. They receive 85W RMS between them. I don't know how much they can handle.
All speakers have paper/cardboard cones with foam surrounds.
There are many aftermarket choices for the 6x8s, keep in mind, these are used for low frequency only in the Mach 460 system, so you can probably just disconnect any tweeter/midranges on any aftermarket speakers.
The only aftermarket speaker that I know of for the 2 1/2 inch midranges is made by Swiss Audio. I do know their speakers are too deep for the front window mounts (the front speakers in the Mach 460 are the exact same setup as the rears i described above), but I have never sized them for the rear deck.
The mach system is kinda a wild beast when you start playing with it, really cannot change out components and have it sound good unless you change
everything, the way the mach system is crossed over is kinda weird and also the speakers (6x8) are 8 ohm and anything aftermarket you buy is 4 ohm, so you can burn the amps out, so new speakers means new amps, if your mach system is not blown and you like it's sound don't waste time changing just some parts out, when it does come time to change do the fronts first these are the ones you hear, backs are just fill noise, any more questions let me know Dan
