Ok, I have had my sound system for almost a year and a half, nothing has gone wrong. I have 2 12" Alpine Type R subs with a Hifonics Brutus 1500 watt amp in a ported box. Also I have a Rockford Fozgate 1000w capacitor (I think it's 1000w, can't really remember for sure). On day on my way home I had played a loud song and the next song sounded strange. Well, I pulled over and my subs had stopped producing any sound, at all. I messed with the wires and it started again so I went on. Now nothing comes out of them. I have looked at all the wires and don't visually see anything wrong. My amp has power going to it, my cap. has voltage, and my head unit is working fine. The other speakers are also fine in my car, it's just the two subs. I don't think they are blown since then I would still have some sound out of them, but I don't know what's wrong. Also, whenever I start the subs I hear a single "pop" sound, then nothing else. Any ideas, I need some help please

A blown sub doesn't necessarily keep making sound; it depends on how it's damaged. Check the subwoofer terminals with a multimeter set for resistance. If they're dual 4-ohm Type R's, then you shouldn't see a reading below about 1.5 ohms. If either sub shows a lower resistance, then you have a damaged subwoofer. One blown sub can shut down the amplifier too, so neither makes sound.

k, thx, I am at college right now but will be going home next weekend so I can use my dad's meter to check the subs.
