That is because your impedance is not correct. You probly have 4 ohm woofers wired in parallel. Try putting them in series. That will put your impedance to 8 ohms the amp will not clip, or go in protection that is what the red light means. Good luck

SOURCE: protection light turn on with sound

It's likely that the amp is defective but you should check the shield ground of the RCA signal cables before sending the amp off for repair.

 

Disconnect the RCA cables from the amp.

 

With your multimeter set to ohms, measure the resistance from the outer shield of the RCA cable to chassis ground. If it's more than a few ohms, that could be causing your problem.

 

If this is higher than a few ohms, short the meter's leads together to make sure the meter will go down to 0 ohms.

 

To check the shield ground of the head unit (assuming that the head unit is driving the amp directly), disconnect the RCA cables from the head unit and measure the resistance from the RCA output shield to the case of the head unit. It should essentially read 0 ohms.

SOURCE: unwanted bass coming out of my subs

there has to be sumthn hooked up wrong bc i have had same problem with my 12' subs but it was simply a matter of my rca jacks but sense you have checked them try rewiring the speakers if that does not work then your rca module may be burned out within the amp..iso then check the amp by taking the cover off and making sure nuthn is burned on the inside.or if any wires are loose or touching.

SOURCE: power light turns from green to red protect mode and then there is no sound coming from my speakers

there are 2 reasons for it to be going into protect mode 1 is heat 2 is the load on it. if it is going into protect mode soon after it starts there is a problem with the speaker. if it is after it has been on for a while it is that the amp itself is overheating. hope this answers your question

I have a 500 mono. it al of a sudden is shutting off when the bass hits. the green light will flikker and go out but then come back on untill the bass hits again. thoughts?


Yes. It sounds like overmodulation, but you did not specify the volume at which the issue appears. usually loud. Check the speaker for correct ohms resistance, if not correct yoru amp will overload and thermally break the circuit, then reset...

Im a candidate sound engineer, im strugling to set the bass drum from the mixer. how do i set it?


Bass drum by convention is ch1 on the board.
You need a good drum and a good mic

First set eq flat and pfl ch1, set gain control so drum just hits peak/or red when hit hard.

Send ch to drum group (1+2) on board, or route to master (L+R), depending on type board. Then listen to drum ONLY through the system, and adjust eq so it sounds good at low level then turn it up and keep it sounding good.
If it keeps peaking the ch then turn down gain.

There are toys (inserts) you can use noise gates and compressors if available,


Sound is objective and can not be learnt without doing it , good luck. remember good low level sound will always be better than really bad lound sound, start low make it good then make it loud.

Good drums do not need much eq. Get the drum right first.

Hope this helps
Thanks for using FixYa

How to mount a bandpass sub


usually you will get the best sound with the box mounted approximately 3" away from rear of trunk with speaker facing toward the rear of trunk if it is a single speaker enclosure you want to do the same just offset it to one side of the trunk corners always amplify sound however just so you know 10's are not really made for low bass they usually have more of a hard hitting pound instead of a low rumble usually 12's will give you the low bass better and it also depends on what kind of box a vented box would be best for low bass sealed box gives you tighter bass but you need more power ported is good for low bass but gets sloppy when loud and a bandpass is used for loud hard hitting bass

Bass sounds muggy it rattles alot when volume is turned up. It just started to happen. What is happening? The bass from the head unit is at -8 while the subwoofer level is a +15.


Have you had it checked out, if it rattles when bass hits hard, it could be busted, have you had it up extremely loud before? If so, that is probably what done it, otherwise, I would call whoever you bought it from, and ask them if they know anyone who has had similar problems to yours.

Green light turns red on hard notes with kicker 750 mono amp


First off, never, ever replace a blown fuse with a bigger one (especially one that is almost twice as big) unless it's an absolute emergency. Most of the time, the reason a fuse blows is because of a problem with the device (in this case, the amp). By installing a larger fuse, there's a very good chance the problem will become permanent (i.e. busted amp).

The amp could be going into an overcurrent mode when the bass hits and power cycling itself to try and reset the problem. If this is the case, take it to a local electronics repair shop and see what they can do.

It's also possible the input voltage to the amp is dropping too low during the bass hit, making the amp restart. Try putting a 1.0F or higher capacitor on the battery to buffer the power during the bass hits.

CRATE PA-B6350 no output


The 2 speaker jacks are wired in parallel. If your subs are 4 ohm rated the amp is seeing a 2 ohm load and may be trying to protect itself - hence the red light. I would suggest you unplug 1 of the subs and see if the problem goes away. You may have a problem with one of your subs. This amp is probably not the best choice for such demanding work as it is not fan cooled. Good luck.
