Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?

No sound..amp has power to it


Hello eric_sodergu,

**First thing is verifying that the powerlight is lite up, this shows that it is receiving power and is grounded properly.

**Next thing you need to ensure is that the remote wire is connected properly on both the head unit and the amp.

**Third Make sure the RCA wires are all connected properly, try jiggling them around on the amps end to make sure there not just shorting out.

**Check all fuses related to the amp to make sure all the channels are working properly. (Applys to amps with multiple channels and fuses)

If all these things are fine, then the sub could very well be blown. Did you have it up loud before it stopped working ? You said it was working fine then just went all quiet, did the head unit power down as well ?

Post back with any further info or questions so that I can assist you further.

Buzzing sound from woofer when I plug in


If the woofer works fine when plugged into any other port, I would say that you have a connector on the receiver that has a loose connection or possibly a cold solder joint (poor or broken solder joint). RCA jacks can be stressed quite a lot especially if you use cables that have very tight connectors. The female RCA jack gets wiggled or twisted when trying to remove a cable and this causes solder joints to crack. I would have a look at that connector on the receiver..

Subwoofer to receiver hookup


In general, there are two ways to hook up your sub-woofer. First using the high level outputs from your receiver ( speaker output from the front R & L speaker terminals ) run a set of wires from the outputs to the speaker inputs on the sub-woofer, you do this in concert with the speaker wires going to the front R & L speakers which you then attach to the R & L speaker outputs on the sub woofer amp. Note that the sub woofer doesn't power your front speakers, the connections from the sub amp are just a pass through connection where the signal needed by the sub is parasitically taken from the inputs.
Second is via a low level output from your receiver / amp to the low level input on your sub amp. This is normally done via a RCA type of patch cable and connected to the sub woofer RCA jack on the rear of the source receiver or amp, Next run the patch cord to the sub amp an into the RCA jack input. IF you have a right and left input, use the Right input.

Woofer making horrible noise! HELP!


Think as an expert... Probably from my experience repairing woofers etc... the cone (1) or the spider (2) isn't well glued onto the woofer skeleton(or both???) The woofer cone must be absolutely centered or else you will get those clicks in low frequencies(you also get them in higher frequencies but you can't hear them!) I must say that it is very difficult to repair a woofer by your own. I suggest to return it back where you bought it and take another one (i suppose that you have a guarantee ha?).
