Subs just quit

All I know is when I parked the car it was playing. When I got back in the car the subs weren't working. Checked fuse and connections everything was tight. I did notice before that that it sounded like it was loosing power. It didn't bang hard after a while like it was getting weaker and weaker. Please help! Could battery be the problem?

It's probably not a battery problem; sounds more like a sub or amp problem. Check the sub's cone and see if it siezed up or if you smell something burned, also check the amp to see if you can smell the "burnt" smell. It's unlikely that it's your battery, because if it were nothing would be working properly. Take you subs and amp(s) to a good shop and ask them to bench test each item.

Yes and Yes. If bypassing that noise filter, has no effect your subs could have blown.

Did you know there is a fuse on the back of the radio and one on the amp? Have you checked them? If the radio is working and no ssound it could be the radio, speakers or wiring. In your case it sounds like either the radio or speakers.

Problem with subs and amp


I would first suggest un-hooking the subs, and hooking them up to another known good radio other than the one its hooked to now. Just to make sure you didnt blow the speakers. What is the wattage of the subs? Then if the speakers do work I would hook them up bypassing the amp just to see if the problem exist before or after. Come back after doing this. Thanks

Why does my subwoofer just all of a sudden quit when it has been workin good?


is it the subwoofer or the amplifier that has quit. check all ur wiring that it is all connected and no shorts. check your voltages with a multimeter. ( available for $10 + from local jaycar etc) connect your sub to a set of wires from one of your car speakers. if there is some sound the sub should still be good.

Check your battery connections and fuses as well, as they can cause issues

Subwoofer buldging out problem


When speakers are wired in the wrong way the will do the "pushing out" you're describing. Basically the polarities have been reversed and if kept like this over a period of time will blow the speaker. Best thing to do is to disconnect the power by the negative on the amp and take out the fuse from the power supply. Check the wires running from the amp to the subs, negative to negative and positive to positive. I know it sounds basic but many people do mix it up! I would also check to see what channels the subs have been wired into?

Best way is to have one sub from channel 1 and the other sub from channel 2 for example. Or if its a bridged 4 channel amp, have 1 sub running from channel 1&2, and the second sub running from channel 3&4 still making sure of the polarities. Again this all depending what kind of amp and sub you have.

-----------------------------
For example;
A 4 channel (bridged) 1000W amp. 250W max per channel or 500W per 2 channels! So if you have 2 500W subs, by connecting one to a single channel will decrease subs ability due to the lack of power supplied. However by combining 2 channels you optimize the output!
---------------------------

Once you know all your wiring from your amp to subs are ok/good connections/good wires etc you shouldnt have to "wiggle the wires" to get it to work as this is just a bad connection. Also ensure that no 2 wires are touching. Make sure that the master volume on the amp is turned down. You dont need this to be on loud at all, in fact far from it or you'll risk damaging both the amp and subs!

Hope this helps!

Car subwoofer issue:


Are the wires connected properly? The SUB may be a dud, do you have warranty. Maybe there is not enough power getting to the SUB from the amp. Is it connected to 2 channels?? It will not play if only 1 channel is connected.
