Any other place to buy the 6 x 8 door speaker for the mach 460

 

go aftermarket.

 

not really. The mach woofer is an 8 ohm woofer and replacing it with a standard 4 ohm full range speaker will not do. The closest I have seen was a 4 ohm dual voice coil speaker but even then it is not the greatest. If you have replaced the deck then you can slap what ever you want in there if you bypass the amp which is easy to do.

 

the last ones i changed out were 4 ohm
