When i turned the bass up to high on my head unit my amp cuts out on overprotection, just for a second and them comes back on. why?


go into your settings in the deck by holding down the volume on most models for 10 seconds then change your hpf settings and your lpf settings your bass will sound much better and not cut out. hpf recommended 160......lpf recommended 140.... good luck

VR3 Amp Protection Light problem


Looks like you have covered all the basics.

The remote wire is the switch that turns the amp on and off. So you are probably just killing the power to the amp.

Sounds like a short in the amp itself if all the input and output wires are disconnected and the protection is still coming on.

My pioneer 600w amplifier cuts at high volume...


Are you sure it's not a problem with your head unit? When you mean cut off do you mean the whole amp loses power or power lights stay on but sound just cuts out? If you don't know have a friend turn up your radio if you don't have a remote and whatch the light, power light on the amp. If it goes out then it sounds like a bad ground or the main power wire is'nt large enough to supply proper power to amp. I would check those that I have described first because thats what it sounds like, bad ground or power wire not sending proper voltage. When you turn up the volume your amp needs more power well when you get to a point when you turn it up and amp cuts out or off then it's starving for power or bad ground. Let me know what you find. Also if this helps please rate my help so I can get out of this apprentice status. I have 15 years exp. and 2 degrees in electronics and my business is buying nonworking amps and repairing them then resale them. Thanks

Amp cuts out and back on 30 or so seconds!! Volume has no impact


You need to check the B+ and remote voltage on the amp when it cuts off (assuming that you can recreate the fault).

With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.

Plz Help - unknow problem


Sounds like a short circut protection on the amp kicking in. It sences the power going to the drivers and cuts itself out before damage is inflicted on the subs.
