View Full Version : Very big problem
02-28-2007, 06:15 PM
So today as I was driving, music not even very loud, my sub just stopped working. I figured one of my chords had slipped or something but i made sure they were all right and my sub still didn't work although my amp was on. I restrung the sub to the amp with new wire and still....nothing. Is my sub blown? It is only a month old and figured it couldn't be blown. Although my sub is 750 watts and my amp is 1000 and my sub is the only thing connected to the amp, my amps sub output is not all the way up, nor is the remote bass boost. I did this in order to NOT blow the sub. Ive checked all my chords and everything should be right. How do I know if its my sub? or my amps power output? My amp is on but my sub has NO power. This is frustrating me to no end.

make sure you didn't turn the subwoofer or rca out on your headunit off, I know you can do this with some models.
recheck all your connections and your ground. even tho the amp may be on, it can ground through the headunit.
turn your music on, not all the way and go wiggle your amp around, or the wires going to it, see if it fixes it.
could also be a fuse on the amp..but that would probably keep the amp from powering up.

From what you said, your sub is not blown. It would have popped and you would definitley smell it. Check the wires inside of your box, your rca's behind the radio, and your grounds like said above. Hopefully this fixes it, I know how frustrating this can be.

I have just tried both of these things. I restrung it yet AGAIN this time making sure everything was perfect. Im grounded, im wired to the sub, my rca cables are fine. This one really baffles me. I understand that the sub would act up if it blew but I cant think of anything else it could be. All the sudden it just stopped working, without any cables or wires falling out. I dont think Ive ever been so mad...

did you check and see that amp actually turning on? check fuse on amp?
I know that's something you probably checked at first but something easily can be forget to check so just making sure.

what gear do you have exactly and how did you set your gains?

Yes my amp is on. And my gains were not set all the way. We did this purposely to try and NOT blow the sub. I still cant figure out what the problem is other than my sub just wont work.

this happened to me a few days after i put the new system in my truck. mine ended up being my rca's were junk. i put a new set in and havent had a problem yet. if you got another set of rca's sittin around hook them up to see if that doesnt work

Or do you have access to another sub or some crap speakers that you can plug into the amp to test it? If you plug something else into the amp and it still doesn't work, you got a bad amp or connections to the amp.
Try to work from the back forward. First swap out the sub with another or some other sound producing device that you might not mind destroying...then try swapping out amps if that is an option (if not go on to step lasto)...then test/replace the connections to the amp...then the head unit connections...then if all else fails, replace the amp (only if you can't swap it to test for functionality).
