so the other day i was driving my car (99 GT) listening to music, and the bass randomly cuts out. so when i get to my destination, i slide out my head unit, unplug the cluster and the rca cables, plug them back in, and the bass is fine again. then the next day, it cuts out again, except this time when i try to do the same steps, the bass doesnt come back. i checked all of my fuses and they all fine, and my mach 460 amps still heat up when the car radio is on. the stereo system is bone stock mach 460 with the exception of an aftermarket head unit. i had a Pioneer deh-1200mp and someone told me the rca output went bad in it, so i bought a new one (pioneer deh-x3500ui), but the problem still persist except this time, i can only hear the sound in the front of the car. ive asked around and what most people think is that it could be dead amps, but i didnt think that was it because the bass went out and then came back, could it be this? im lost in the dark here, so any suggestions or advice will be extremely helpful. thanks - Dan

You will get better results asking in the AV/ Electronics forum. I bet it is the amp(s).
Check the owners manual also. Seems I remember seeing a mention of a fuse dedicated to Mach subwoofers. That may only apply to the Mach 1000 though but is worth checking.

I've had a similar experience with my 02 mach 460 system. For me I had no bass when I turned the ignition on then 2-3 seconds later it came back on. Later I had some loud crackling then no bass. I still have no bass, but all the speakers work. I am thinking maybe it's the amplifiers. Will have to check with car stereo guys i guess.
