wat happened to my SUB

so basically i have a pretty nice system n my boat I have a 12 inch hertz/audison mille edition sub. 2 arc audio se amps a 2300 for my sub and 4200 for my interior and tower and a WS420 equilizer. and last week my sub stopped working as i was about to throw a double up. so after checking all the wiring to make sure nothing came loose i was kinda confused on what happened . I took my speaker wires out of the box and my power protection light stayed on on my arc amp and sent it in got a new amp back put it in ... not a peep from my sub.. I have checked everything rcas r good everything is plugged in good... i dont know what to do can this have anything to do with my wetsound 420 that is the only thing that i can think of... i am dying with out my bass please help me people

just bypass the ws-420 and see if that is ur problem then.

get a battery (AA/9 volt,ect) touch the speaker leads of the sub to +, - of the battery, if the speaker does not move your sub is blown.

witht those amps and that eq you could have easily overdriven your sub and melted it. try pressing on your cone....i bet it's stiff as a 2x4.

the sub isnt stiff thats what has me dumb founded it feels perfect...

brandon that was my next move thanks

sam i will try that. thats a pretty nice trick with the battery ive never thought about

any other sugestions are appreciated I just have no clue and im not around my boat to mess with it right now

Try to hooking your sub to your other amp using a jumper wire to see if you get anything.

Use a meter to measure the ohm loud at the end of the speaker lead by your amp. Make sure you disconnect from your amp.

Hook a test speaker of any kind to the output of your sub amp.

i have no idea i already tried helping out out there houser haha
