I have a Pyle Audio 1,000 watt amp running 4 channels. I have a 12'' sub hooked up to it and it goes into protection mode. I troubleshooted it by removing all the wires and starting from the beginning. i found out when i plug the RCAs in, the sub goes pop and then goes into protection mode. Any ideas on how to fix?

Things to check: Is the wire between the amp and the subs heavy enough to pass 167 amps? 2000 * 12 = 166.66666 amps. Max volts on the subs are 10 volts....close enough. Are you sure you're using the line out on the head unit? You may be over driving the amp if it's anything else.If the head unit doesn't have line out connectors then you'll need to get an attenuator for each channel. Do you have caps on the 12 v power in wires? They'll keep the headlights from dimming and the alternator will last longer if you do.
You need to bridge 2 of the amp channels to each 4 ohm sub to get the most power from the amp. Bridge channels 1/2 to one of the subs and channels 3/4 to the other one. But the amp is only rated for 75 watts RMS per channel and Pyle products are sometimes rated higher than their real capabilities. So, even bridged and with the rated output, you'll only be getting at most 150 watts from a pair of bridged channels. That's not much for a sub.
you have an unloaded channel,so the voltage is exceeding what the protect circuit is supposed to see.you have to connect an 8 ohm resistor across the output of the unused channel.
do not drive a signal into it or you will smoke the resistor.
a 10 watt will do ok with zero signal input
Not enough juice, check the power and ground connections, another possibility is to have dc in the input, try to use in line filter available from radio shack to cut the dc, also test the with one speaker at the time, you could have a bad speaker (shorted) too.
if you have dual voice coils connect on each seporate sub negative left channel to possative right channel of the subwoofer same to other sub then conect the left possative and the right neggative to your box power terminal same to other sub then conect the two sub outs on your box left speaker positive to your positive left channel bridge then conect left speaker negative to the right speaker possative then connect your right speaker negative to your right channel negative brigdeg to your amp is single coil hook the box its self up the same way to your amp i have two dual voice cooil 12" hooked up to the same amp that way and it rocks without the power protecter turning on
first whats the range in terms of WATTS that your 12" sub can handle in 4 OHMS ? second , lets check the AMP , POWER ACOUSTIK 1800 WATTS , Now thats a lot of power to drive a single 12" sub speaker . your amp is 1800 watts , per channel is around 500 watts , if BRIDGE thats around 1600 watts rms for ONE channel , if your sub can handle that kind of wattage fine , but it will not blow the amp , what it does is shuts down , some kind of protection mode , it will come back on after a minute or so. I suggest to use one channel in stereo mode , or purchase another sub to use the other channel. i hope this helps AJ
