do i need any brackets or mounting hardware to install an aftermarket stereo into my 99 v6 mustang? it looks like it fits right in?

 

it slides right in.. you just need the wiring harness adapter

 

i baught the wiring harness, but only one fitting out of like 4 fit in... the power and everything is on but the speaker plugs dont match up, and i dont even know what wires go where or id cut the plugs off and wire them together..any ideas?

 

you have a mach 460 system or no? i ran all my speaker wires in my car to bypass the mach amps so i dunno

 

well i believe i HAD the mach 460, but they took it out... is that my amp sitting underneath the cd player inside the dash?
