Before I swapped to the 5.0 in my 99 the sound system sounded perfect. Had a nice bit of bass to it (not bad for the stock non Mach 460 setup).

Now, for some reason I get lots of distortion even at mid volume levels. The dash harness out of the my old 94 that I used in this car had the Mach 460 amp and wiring. I installed the bypass harness on my stereo which basically bypasses any and all factory amps and it did the same thing.

I'm at a loss here. I'm probably gonna have to run all new speaker wires because I'm not sure if something is touching or not. I doubt it since it worked perfectly in both cars prior to the swap. Could there be an issue mixing the Mach dash harness with a non Mach body harness?

If anyone has access to the wiring schematics on a 94/95 vert without Mach 460 I'd love to see it. And wiring for a 94/95 coupe WITH Mach 460. I need to make sure there's no kind of crossover/capacitor installed inline somewhere.

will do. I'm pretty sure everything in that kick panel is bolted down the way it should be, but you never know!

Also i forgot... Are you using stock speakers still??? IIRC they are an awkward resistance and wont work with a normal aftermarket head unit without using the mach amps.

They are basically home theater speakers... 6ohms IIRC

Yes, I'm still using the stock speakers along with the factory amp from the convertible.
