Answer
Hi,

It sounds like you probably have separate amplifiers for the subs and the front/rear speakers.  Are these still powering up, or are they dead?

If they're not turning on, then you'll probably want to check the main fuse at the battery (assuming you're using a single power wire with a distribution block).  Another possibility is that there's no voltage on the remote wire.

If the amps are turning on, but you're not getting any sound, then I'd suspect a problem with the equalizer or the head unit's output.

Unfortunately, it's not a problem that I can troubleshoot very easily without having the vehicle in front of me.  The first task is to determine whether the components are getting power or not.  Power problems can be easily tracked down using a voltmeter.  Breaks in the signal chain are a bit tougher to find, but the fact that neither the subs nor the speakers are playing makes it likely that the problem is occurring before the signal is split to the separate amps.

Hope this helps!
