--------------------------------------------------------------------------------

I hear a pop coming from my solo 12 inch sub (which is connected to a mono amp)

I hear it in the following conditions

When the volume transistions from 1 to 0, or from 0 to 1

When I'm listening to the radio and I go from one of my preselects to another (i.e. during that momentary pause)

When I switch sources (i.e. go from radio to CD and vice-versa), (again during that momentary pause)

From a couple of searches I've done I've seen people have similar problems and they called it turn-on and turn-off pop, and it happens when the headunit signal shuts off before the amp or when the amp turns on before the headunit has a chance to turn on.

1) Does this sound like what i have?

2) I saw some turn-on and turn-off pop eliminators for sale on a couple of sites. Would this do the trick? (I read that you can make them to but I'd rather buy them already made, they're pretty cheap).

3) Could it be anything else, I don't want to spend money and time getting those eliminators and find out that they don't fix the problem.

4) Does it seem wierd that I'm having these problems now because I have a pioneer HU, a pioneer Amp, and a Pioneer Sub. I would think Pioneer would engineer their parts so at least they'd work together? Also I had a previous set-up with the same HU and a JBL amp and a pair of smaller Pioneer subs and I never had these issues before.

also possible grounding problem, check up on the big 3 wires upgrades to your electrical system

Some amps just exhibit a certain amount of turn and/or turnoff noise.

I have the same thing but also when ever I hit a bump the sub pops a little.

make sure nothing is touching metal. I had this problem once with a stereo I was installing and the terminals of one speaker were touching metal.

The ground going from the battery to the fender and the ground strap from the motor to the fender/firewall are the main ways your amp ground gets back to the negative on the battery. If you upgrade these you will reduce possibilty of of your ground causing the problem.

From what you describe it sounds like anti thump/pop curcuit in your amp is not functioning properly, could you possibly get the place you bought the amp from to exchange the amp with the same model and see if the problem still exists?.

Problems like this are tricky and usually require some trial and error to correct but heh, thats the fun of it. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
