You blew the speakers. The speakers were probably not made for that much power and the voice coil blew. If they were stock speakers, then they are defenetly blown. Stock speakers are not made for much power at all, and will more than likely blow with any extra power given to them at all.

Guys whats up. I have a infinity 475a and when i turn up the gain it makes a loud popping sound. It damaged my speakers. Got other speakers but still the same. A friend mentioned about dc leaking or...


Static electricity build up, and the popping you hear is when the static electricity builds up to it's maximum, then it arcs to ground.... what you think is from the speakers.and then the process starts over.

I have a pair of JM lab Electra 905 speakers, running through a DNM amp and power amps. When powered up, the left speaker makes a very loud humming noise. This has happened recently. I haven't changed...


Hello
Switch on your amp, keep its volue down to extreme low, and listen if there is still hum through the left channel or not. If still there is hum, the left side power amplifier section inside the amp;ifier is faulty. If htere is no hum at this state, hum enters thorugh the audio input terminal, and the input wires must be checked for open sheild connection. OK.

This happened with a DV9000 recently and the speaker assembly had to be replaced. I found one on ebay for 5 bucks. Need to remove the power button plate and unscrew the speaker assemblies and replace.

Component speaker not working


The easiest thing to test is to try swapping the connections of the front component speakers at the amp connections. If the problem follows the speakers, the issue is probably with the speakers. I would triple check (again) the speaker wire connections. It's also possible the crossover for the driver side component speakers has an issue (thus why the tweeter worked for a while).

If the problem stays on the drivers side, the issue is probably with that channel on the amp. Triple check the RCA connections for that channel.

It's much easier to test other speakers on an amp channel versus trying to check it with a meter.

If the driver's door is "abused" often, my initial thought is the wiring at the speaker or the wiring in the speaker (to voice coil, within the crossover, etc) is the most likely culprit.
