Re: clip light

A shorted speaker, a pinched speaker wire or a short in the amp, itself. Try to disconnect the speaker wire from the amp. Did the clip light go out? No?? Ok take out the amp and send it to the service center as unless your a tech, there are no user serviceable parts inside as its all solid state. Good Luck

Temp light wont go off on my amp

Shorting a car amp's speaker connection while in operation tends to pop the lids off of the capacitors. If you are not afraid to uninstall the amp and open it up, look for popped caps and oil stains on the circuit board. If this is the case, find some place to repair it or repair it yourself.

Amp never shuts off and protect light will come on when turned up

Just to make sure I understand you, when the protect mode turns on the amp still stays on? If so my guess would be that you are pushing the subs so hard that the amp is just starting to clip (distort) because you are pushing either the amp or the subs or amp and subs to their limits. Clipping is not a good thing, but at the same time it usually sounds the best just before clipping. You may need larger gauge wire or a capacitor to help the amp get higher voltage. I will post a link on clipping.

I'm not sure this is your problem just my guess.

Hope this helps.

I have a JVC ks-ax302 amplifier and the sound is surging(on/off) the sub still has sound. I noticed when the sound is surging the green light on the amp also surges. I checked the power inputs the both...

Check the RCA cables, this is generally a sign of the RCA cables grounding in the insulation. This would be if you are getting a sound like a heart beat from your subs.

This is a 160 watt amp though.

Could also be a weak ground. Make sure you use a solid ground like the seat belt bolt or brace behind the back seat. A solid ground is best if you remove any paint before bolting the ground down as well.

Also might be the amp is clipping. Try reducing your gains and double check to make sure you are using the proper wiring diagram. This is a 2 ohm stable amp, any lower ohm load will cause problems with the amp.

How to turn off the clip light is on red it does not turn off?

You can't, the clip light is just that...the signal is being clipped/distorted and the clip light comes on to protect the amp/speakers from blowing. You need to check your signal and then cables and wiring to see where the problem lies, chances are your volume is too high and your over working your amp....(turning the volume too high when the amp doesn't put out enough power for your speakers and this distorts the signal causing it to clip)...Try turnig the amp down, should not be any higher then 1/2-3/4 of the way never max. And if that doesn't work check your signal from the radio as well. If it works fine with the volume down and doesn't clip then your amp is too small for your needs and your need to invest in a larger amp for more power...Look for RMS watt ratings at 12-14 volts not max watts at like 16-18volts (those are fictious #'s and those amps should be avoided)

Soon as i turn on my QSC RMX2450 the clip light comes on for Ch 2

Sounds like an output going bad. Try to get some electronic contact cleaner and spraying on the circuit board. If its corroded this will help clean the circuit..

The green light stays on but sound comes out like a skipped cd

Check your RCA jacks. Wiggle them around a little, and see if it changes anything.. It could be a bad RCA< or the inputs them self. Could also be caused by over loading the amp. if nothing changes when you wiggle the RCAs then disconnect one of your subs. If disconnect the sub makes it play right then your impedance is to low, and is causing the amp to clip.

Problems with Infinity Amp 611A

are you running a large ground wire directly to the battery negative terminal?

No sound

I would try it without the slot for the additional amp. However, there is a chance that it is fried. When its powering up I would check the voltages with a multimeter to make sure everything there is in order.
