Probably a loose coil or bad ground in the amp itself. Contact, ask for Jason, he can help you and is the best out there. The problem you're having is extremely tricky to rectify, I had an amp with the same problem at it stumped multiple techs, some that had been in the business 35 years, yet Jason got it solved.

How many watts per channel?

Hi Peter.

Your question is fairly open, so I'll give a couple of answers to anticipate:
  1. If you're wanting to match the amp to your speakers, you want to go above the power rating of the speakers, but not hugely so. If you have 40 watt speakers, you don't want a 40-WPC amp because it'll be running at full power to use the speaker capacity, and it'll probably sound awful. Amps are much smoother when you're not coming close to their capacity, and your music will sound better. Likewise, a 40 watt speaker running at 40 watts will also sound pretty bad. The limits on speakers usually allude to damage thresholds, or limits where they'll distort like a stump-talking politician. Talk to a dealer about how much 'THD' (Total harmonic distortion) the amp has at different power levels, and how to match it to your speakers.
  2. If your goal is to be able to announce your presence from a block away from the subsonic thudding escaping from the interior, you'll still want to look at the speaker ratings and spec the amp perhaps 50-100% higher than the speaker capacity. Full power on a big subwoofer will still sound crummy if you're driving it to capacity, but in some cases people won't care so long as it's loud. (I don't advise this route - I'll tell you from first hand experience with loud environments as a younger person that being several decades older and constantly missing parts of conversations is no fun)
Hoping this helps!

you could have a shorted speaker I would disconnect all speakers and test them 1 at a time to see if you can get the amp to make some sound before I did anything.

My powered mixer Behringer is buzzing

Make sure the buzz doesn't happen because of feedback of speakers into mics. When feedback is processed it often goes to a buzz instead of the usual howl.

Also check that you are running adequate inout into the effect since a very low inout will incur digitizing noise and loss of signal=to-noise ratio.

To get rid of the buzzing sound just go to walmart and in the car stereo section buy the $10 rca ground loop isolator, this is the best way to get rid of amp noise

I installed a 475a to my door speakers and when i turn the power up on the amp my speakers make loud popping noise any idea on wat it could be

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.

Fan on amp runs constantly. will this drain my battery?

Yes, and would imply that the amp is powered up all the time.

You should correctly wire your system by

1.Connecting the constant 12vdc input wire to a constant 12vdc source to power the in-dash head units memory.

2.Connecting the switched 12vdc input wire to a switched 12vdc source to power the head units primary functions.

3.Connecting the remote output wire (typically a blue wire) from the in-dash head unit to the correct terminal on the amp, so the amp will only power up when the head unit is on.

4 Remember to run the signal (speaker) wires in a chase separated from the amps power wires, so as to avoid a buzzing noise in the speakers.

5. Always use an in-line fuse on the amp and the head units main power wires.

Note: A properly powered amp will produce a better sound quality then if it were under powered, so be sure to use the proper wire gauge as your amps power supply.

Good luck

Protection mode

Disconnect all speaker wires from the speaker terminals of the amp. If it powers up and doesn't go into protect when you increase the settings, the wiring needs to be checked. If it still shuts down, the amp may need to be repaired.

Does it shut down or make loud noises when you move the RCA cables where they plug into the amplifier?

Kac-8401 buzzing noise

If the buzz is real high pich the faster you go and lowers to a low pich when you slow down then it is you alternator on your engin.
The only way to stop this is to go to an caraudio store and buy a noise filter which will stop the noise. The only bad thing about getting an noise filter is that it will cause the watts on your amp to go down a little bit because the noise filter runs your power source through a box with a step up transformer and a step down transformer. I hope i helped you with your problem

You need to use a multimeter to see if the remote turn-on voltage at the amplifier is dropping to near 0v as soon as you switch off the head unit. If it's not, you need to determine why it's not switching off quickly.
