When I turn on my amp it causes the subs to pop, not loud or hard but low and soft repeatedly. When it does this the protection light comes on and goes off. What would cause the amp to do this and how can I fix it?

Re: How to fix a popping sound
This problem could be a normal thing in the amp, or there could be a problem in the muting circuit. I would contact the manufacturer to check with them , if theres any common issues with this amp. Also I've seen custom car amp installs where you hook up a speaker delay circuit that you can build from a few parts like a couple of capacitors a few resistors , a 555 timer IC and a relay with high current contacts. I have also seen these already factory nmade in good auto stereo shops. Good Luck

If the 10k resistor is the variable volume one then change it.Some sub amp plates have epoxy all over the pcboard.Hard to remove type.I think yours is soldered to a sub pcb and need soldering experience to remove.
First try to find the source of your problem. The easiest way would be to try your sub with a different audio source to see if the problem still occurs but is sounds more like there's a problem with the receiver.
If you are driving the speaker too hard it will pop. This caused when the voice coil is driven mostly beyond the pole pieces of the magnet. Without the magnetic field the back EMF of the voice coil drops off and the current shoots up. The voice coil can't move farther so there is a discontinuity of movement which causes a pop.
200 watts is a lot to put into a 12 inch speaker so you have to be careful to not drive low frequencies at excessive volume. It is both very hard on the amp and doesn't do the speaker any good either.
If you want loud lows, you should get a subwoofer of at least 15 inch speaker to handle the lows.
u might have to turned your amp so u can play both subs your amp might be to small to run both subs at the same time an u gotta play around with the settings on your cd player so when u blasted your subs it has that nice bass to it not that poping sound.
there has to be sumthn hooked up wrong bc i have had same problem with my 12' subs but it was simply a matter of my rca jacks but sense you have checked them try rewiring the speakers if that does not work then your rca module may be burned out within the amp..iso then check the amp by taking the cover off and making sure nuthn is burned on the inside.or if any wires are loose or touching.
If the sub isn't working, you won't get a pop. All you need is a small speaker. Don't need a sub, you just want to test the sound. I recently blew 2 subs, no smoke, no smell, no sign of being blown. Absolutely nothing from the subs.... In the past my sub locked up. You can take your sub out of the box and hook the + and - to the battery to see if you can get the sub to pop there. I believe a small box will push a sub into a deep excursion to the center of the cone. I have 2 lanzar VW12D's that just quit. I hooked a 6 x 9 up to my amp and low and behold I had sound! Try that and see what you get...
If you Wire the 13 w7 in parallel you get 0.75 ohms which this amp is incapable of handling, that's why your speaker is popping. Be carefull cause this setup could ruin both your amp and sub. You have to wire that sub in series so that the amp "sees" a 3 ohm load which it's best suited for.
You most likely have a shorted or damaged speaker, which is causing the internal amp chip to shut down (but does not affect the preamp outputs). A test you can do is to fade to one speaker at a time and turn it up to se if it shuts down. Repeat with each speaker until you find the one that causes the fault. Then replace it.
It sounds like your amp chip has gone bad, here is some thing you can try turn on your unit then start tapping on top of with your finger not hard see if the any of the pops matches your finger taps some times when the chip starts to go out it well act like that.
