Problem with an eclipse EA3422 amplifier

When the stereo is on the volume cannot be turned up or the sound cuts out completely. The speakers were checked out and so was the amp by a professional but they say that the speakers are fine, however they thought that initially the ground wire had shorted out the amp, but when they took the amp apart they couldnt figure out what was wrong with it. They tried to replace a few parts and to no avail they couldnt fix it.

Re: problem with an eclipse EA3422 amplifier

Your problem is with your stereo/radio, not your amp... Take a friend amp and connect it up as you have yours and see if it does the same thing.

Car Ampli Problem

forget hooking this on a subwoofer. this amp produces only 50 watts per channel at 4ohms or 70 watts per channel at 2 ohms RMS...
If you try bridging the sub, it will only give out maybe 100watts bridged.
So..... if your sub is, lets say 1000watts RMS, youre just going to bust your amplifier to smoke...
Find a more decent and powerful amp. This amp is only intended for separates and lowend subs with an RMS of 80 to 150 watts

What ohm is your sub running at. Sounds like your runnig your amp to low an impedance causing it to thermally shut down, when it cools a bit it turns back on. Either that or you have wires crossed somewhere. Check your wiring and make sure the load of the speaker does not fall below the rcommended ohm of the amp. Usually 4ohms mono and 2ohms stereo

Car speakers cut out (no sound) when volume turned up

I would check the crossovers.
If you are turning it up too loud, then the amp may be clipping (into distortion) and this is then setting the protection circuits off in the crossovers.

Amplifier cuts out when turning the gain up

Make sure the amp is getting good power and ground - there should be 12V across the two terminals. Also make sure you're giving it the proper ohm oad - how do you have your subs wired up? Do your headlights or interior lights dim when this happens?

this is a safey feature in your amp. you are drawing too much power for the amp to put out so i shuts off when the breaking point of the total rms calue is reached. i would suggest getting a more powerfull amp, a larger ground/powerwire combo, or a farad capacitor to balancethe powerin andthe power out.

Interior speakers cut out when the volume is turned up

You may have speakers of an incorrect impedance attached to the unit since the problem occurs when audio signal level is increased and the current goes up.The unit is shutting down to prevent damage. I would check the speaker connections and make sure that the speakers impedance are matched for the unit you are using.
