If your EB is a Gen1 with the Mach Audio system, then it has a sub. If you have no bass at all (like I did when I got mine), then your sub is probably blown. Ford designed the system to turn the bass off to avoid damaging anything if the sub goes out. Replace the sub and you should be good to go. There are plenty of walk-throughs on this site if you need help.
Well lastnight I took it all apart, I have 12 v power going into the amp, but no output to the speaker, so I'm going to guess it needs an amp?
