Well, none of the fuses were blown. Now, after some online reading I think I may have a broken ground.

Here's a question... What would happen to an amp with no ground? Would it just not come on because the circuit isn't completed, or would it immediately blow, or what?

Thanks!

BTW, the subs are producing sound, just, not hardly any. Its just enough to notice. However, there is no visible vibration like there was before I started having issues.

If there is no ground, you're fine. Trouble is there isn't simply the main ground line to worry about. You have RCA or non-line level outputs from the head-unit that the audio circuit can use for ground. Then, should just your main ground be crappy or unconnected..

That type of scenario creates extra resistance, which equates to heat, and in the case of it trying to go to ground through circuits not designed to handle the load you fry ****. This is exponentially multiplied with higher wattage amps. If the only ground it could go to was the main one and it was just crappy you might have burnt something out from the extra strain/heat, but less likely.

People fry their head-units all the time over a bit of time due to the antenna ground having less resistance than the actual radio ground, or they notice it works once the antenna is plugged in and don't bother to wire the main ground for it at all. It's generally not instant as the wattage is under 30 for most head-units, but people burn 'em out all the time, not to mention not getting what they could from the unit in the first place due to the added resistance and heat.

A pretty basic electrical concept for you: Electricity follows the path of least resistance. An addendum to that concept is that if there is any path for it to follow, it will, intended or not.
