Is the power LED red or green?

If it's red, try reading through the following page to make sure that the amplifier is the fault and not somethig else in the system.

Speakers cutting in and out at high volume

The amp is going into protect on the two channels powering the speakers. Turn down the gain on those two channels. You also may want to consider crossing over the speakers a little higher than they are now.

The rating on those speakers are way too high. 6.5's and 6x9's will take 50-100 clean watts tops before they start to break up.

The best solution to get it perfect is....unplug the subs. Turn the gain on the speaker channels all the way down. Then turn up the deck 80% as high as it will go. Play a song. Then increase the gain on the amp until the speakers are as load as they go without distortion. Shut off the car, replugg in the subs and do the same thing. Gain on sub channels all the way down, deck then to 80%, find a bass heavy song, then turn gain up until subs become distorted. If you do this procedure your speakers and subs will be "gain matched" to the proper levels.

Good Luck

Hi,I am Udo from Germany. Please execuse my bad English because I have learn it at school 25 ago. My problem is: I have a Ultimate Sound T3 Series 4070 Car Audio Amplifier with 4 channel and I want play...

Run a wire from the negative side of one speaker to the positive side of the other speaker. Then plug the remaining two wires into the amp. The positive wire coming from the first speaker goes to the positive on the amp on the first channel. Then run the second wire coming from the negative side of the second speaker to the negative side of the second channel on the amp. There for giving you the max power of your amp to your speakers. Hope this was helpful!!!

I have a kenwood kac-8452 4 channel amp that makes the speakers pulse after the volume gets turned up to 10. I also have a kenwood amp doing the same thing with my subs. any ideas?

Its not pulsing, its called clipping. The sound is being clipped due the amp being pushed past is power capacity and distorting the signal. This will damage your speakers very quickly. No amp should be turned more then 3/4 up. If its not loud enough you need to purchase a larger amp or be comfortable with the wattage it produces at 3/4 volume. You may also have speaker wires touching/crossed causing th issue.

I have a 2600 watt Power Acoustik Gothic Amplifier and two 12 inch MTX 7500 superwoofers. When I go to hook up both the subwoofers, it seems like the subs won't work as well, but when I only hook up one...

look at the speakers, is one jumping out and the other drawing in? If so try this. Hook one speaker up normally, reverse the polarity on th other. Hook it opposite how you hooked the other up. This won't hurt a thing but it may cure the problem. Sometimes the amps get wired up backwards inside. I know for a fact that fosgate does cause mine was.

Car amplified speakers...massive bang...

This kind of problem is often caused by transients in the signal
processor as it powers down finding their way into the signal path,
which the amplifier then transmits to the speakers.

Usually this can be solved by adding a little turn-off delay to the
processor. This allows the processor to stay powered on for a short
time after the amplifiers have powered down, thus preventing the pop.

Many components sold today (such as crossovers, equalizers, etc) have
delays built-in. Read your manual to see if it is possible to set this
delay on your piece of equipment or be sure to look for this feature
during your next car audio purchase.

If your processor does not have this feature, you can build your own
delay circuit with a diode and a capacitor. Add a 1N4004 diode in
series with the processor's turn-on lead, striped side towards the EQ.
Then add a capacitor in parallel, the (+) side of the cap connects to
the striped (processor) side of the diode, the (-) side of the cap goes
to ground (not the radio or EQ chassis - connect to the car chassis).

Experimenting with the cap value will give you the right amount of delay
before the EQ shuts off. You don't want it too long, just long enough to
make sure the amp is off before the EQ powers down. 220 - 1000 uF is
about right, and make sure the cap is a polarized electrolytic, 16V or
higher. Also keep in mind that the diode will introduce a 0.7V drop on
the remote wire, which can cause the processor to power down before the
rest of the system.

Amp will not turn on

That is the way it should be connected. If the protect light comes on you have a different problem than the power connections.

Try to turn it on withour any speakers connected, if it turns on then, you have a bad speaker or you may may the speakers connected inproperly.

If it still goes into protect you have an internal problem with the amplifier.

An internal problem would be something you would need a professional technician to check out. Could be in the power supply circuit, but most of the time it is a blown channel.

If you require any more help feel free to ask,
And if you found this advise to be helpful a "FixYa" rating would be appreciated.

Amp blowing speakers on one side

Either the speakers are old, or you need new ones. If you put new ones and it blew them again, then check the power rating, and make sure it is wired properly. if it is wired properly, then make sure the speakers are designed to handle the power of the amp> :) any other q's ... just ask me:)

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.
