Over the weekend My sub suddenly stopped working and then came back on randomly a few times and when it did come back on it worked/souded perfect. The amp light and fuses seem to be fine. I am wondering if this could have something to do with the Head Unit? Is there a way to isolate the problem/fix it?

When it went out, had you been jamming on it for a while? Was the amp pretty hot to the touch? Maybe it's thermal protection circuit kicked in. Otherwise, I would check all your wiring- make sure all your connections are solid, and there are no pinches or wires grounding to the metal of the car. The last thing I would check are the tinsel leads on the speaker (braided leads going from the cone of the speaker to the push-terminals). Lastly, I would check your speaker's voicecoil continuity by connecting a multimeter to it's terminal, setting it to continuity test (meter sounds a tone when leads are touched together) then lightly move the cone in and out while the meter is hooked up to it. You should hear nothing but a solid tone. If the tone goes out anywhere throughout the travel of the cone, your speaker is done. So to re-cap, your problem lies in one of three areas, Amp cutting out (probably due to protection mode), Intermittent wiring connection, or bad speaker.

Correction. I had been driving for 3 hrs when it went out for the first time, then it came back on for a day then i started it up the next day and it was gone for good. I checked the connections and they all appear to be good not 100% though. What i did do last night was disconect the sub leads and hook them up to on of my 6.5" and the 6.5 went crazy so I am getting power! The sub just isn't working...is this a good test? Im guessing the broken sub is just trying to draw so much power b/c it is broke that my lights started dimming. The silver braded lines on the sub are fine. How do i check if the voice coil is shot? There is NO sound coming out of the sub at all! Thanks!
