My sub stopped working, and I found a blown fuse at the battery going to the amp. I replaced it and it blew as I plugged it in (30amp). I unhooked the sub from the amp, and replaced the fuse again and it didn't blow. So I figure it's probably the sub, maybe, I think? I don't know a whole lot about speakers, but I went to a site that said to use an ohm meter to test the coils (however it didn't say how). The sub is a 10" JL W3 V2. I placed the ohm meter on each set of conections (seperatly) and one said 2.0ohms and the other said 4ohms. Is that bad? or is there a correct way to test it? The back of the sub says 4ohm dual voice coil. The amp is a rockford fosgate 300w mono amp. So if anyone knows how it should be and can offer any advice on how to properly trouble shoot and how to fix it that would rock! (bad pun!).

first you should make shure your getting power to the amp. turn your car on ( or ign-II, accesory). take a test light or volt meter. ground one side off then check the lil blue wire on the amp called remote turn on. check if that has voltage, then check the big fat wire, usualy red check if that has 12volts. if it dose see if a light on your amp is on. check the secondary fuses built into the amp.
also when you said you replaced a 30 amp fuse. was it from the main wire goin from the battery to the amp? becuase the original fuse should be somewhere around 100 amp.
