Question about Kicker (ZX350.4) Car Audio Amplifier

1 Answer

Protection light comes on at higher volumes. Flawless install and correct gauge wires all around. I sent the amp in for repair as it didn't work brand new and when it came back today I noticed on the comment sheet it said reapired stripped speaker terminal. I know thats not the problem and I'm dissapointed they didn't look any further. My components I'm running are infinity kappa and they use the supplied crossover network. The speakers pull a 2ohm load but this should be no problem for the amp. Any thoughts?

Sony HCD-GT222 Hi-Fi CD and cassette deck with tuner, suddenly started to shut itself down at volumes higher than 50%, after three years of flawless operation.


It's thermal; protection is happening probably due to bad ventilation. Fuzz and dust can block air vents.These need to be vacuumed out now and then.

Protection light comes on and volume returns to zero. I am using a Azur 540A. This issue occurs when I ride the volume above a certain point, which is NOT any higher than i've been running it for years....


Protection circuits respond to overloads. Unless the protection circuit is faulty there is probably something wrong with the power amp parts located on the heat sink.
It would be a good idea to have the top cover off (on power) and listen for that noise to try and pin it down what is making it.

THE PROTECTION LIGHT COMES ON


make sure your ground is drilled threw thick metal and the paint is scraped off and make sure that all the wires connecting the amp are 4 gauge or higher and if that doesn't do the trick get a better amp that can throw more power

Protection light comes on


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Dou .A thumbs up would be greatly appreciated if this answer is helpful to you. protection-light-comes-lv2kkrmxrai4iihdvw4m3np2-2-0.jpg http://www.nitrobmw.com/

Bass goes off when i turn up the volume


You need to install a heavier gauge wire to your amp and a capacitor. It works fine at low volumes because there is enough wattage from the battery to power the bass output of the amp but at higher volumes the amp does not have enough power.

Heavier gauge wire supplies more poer, and a capacitor stores a reserve of wattage for the amp to use so that it does not run out while blasting your tunes.

Since the problem seems to be sensitive to the volume level, I would be looking at the output wave form for any DC current. Although the protection circuit should detect any DC present, it is possible that some is leaking through. Also, verify that the speaker impedence is correct. If the amp is seeing too low an impedence load, it will work too hard causing excessive heat which will shutdown the unit as well.

Keep me posted.

Protection Light irritation


If the amplifier goes into protect when there are no speaker wires connected to the amp, the amp is likely defective. The most likely culprit is shorted output transistors. If it's new, return it to the place of purchase for repair/replacement.
