Mach 460 has no bass?!?!? Please help!!

[rockinrobin]

I purchased my '99 GT 3 months ago and the stereo was missing. I just bought a factory mach 360 so that it would be any easy plug in...BUT we turned it on and it has nothing but treble?! There is absolutely no bass!! We checked and found that power was going to the amps in the trunk and the speakers...so what could be the problem?? Please help!! Sounds awful!!

Thanks!!

go to a junkyard and find a mustang with the 460 and take the rear amps out of it and try them on yours. Should do the trick. Those amps are prone to failing
