Sub "pops" when car is turned off

15 posts in this topic

So heres whats going on. After I start listening to music pretty loud for more than around 5-10minutes (or just normal level for long periods of time)...when I turn my car off the sub makes a thump or popping noise. I've checked my ground, RCAs and all the other wires for loose connections but they were all fine. I did a little researching and saw that people said to buy a pop stopper or ground isolator. What one would work best for my situation? These are the ones i'm looking at, if you know the problem or a better product go ahead and let me know!

just wondering...how did you "check" your grounds? everyone comes in and says they checked them but when we ask how they actually are, they usually say that its on painted metal on some trunk bolt.

Uh well my ground wire came loose before from not being crimped well enough, so I checked that again and made sure that all the paint was scratched off. I also checked it at the amp to make sure it was snug in there. What else should I do to check it? I'm no pro at this stuff :P

Are you using an EQ? I have Noticed some EQs give this "POP". I get this from just general understanding and Im no expert on the way to fix that. I always say check the grounds if anything is going wrong. I feel sometimes, cheap amps and cheap EQs sometimes are the cause of this but again I have nothing to back my statement up. Just something to check on.

also ive noticed if gains are up too high you get this pop..... have you set your gains properly?

also noticed if your remote wire isnt connected to the remote output wire on your headunit and just to an ignition wire or switched 12v source you'll get this pop also.

Grab a volt meter and make sure you're getting 12+ volts with the car off.

Red probe to power wire @ amp.

Black to ground.

Not using any EQs. I've checked my grounds by making sure the wire is connected good and the paint is scratched off, if there is any other way of checking to see if my ground is good let me know. I don't think my amp is "cheap" its an AQ750,not the best but its decent right?

I haven't set them properly :|. I don't have access to a DD1 or oscope. My headunit has 2.2V preouts and another member told me that i'll probably have to have my gains a little past 1/2 way but not more than 3/4 so I have my gains at or maybe a tiny bit under 1/2 way. I dont go higher than 45 volume (61 max) so im hoping its alright.

I know I need to get it set up properly but I just don't have the money to get a DD-1. I'd have to take it to an audio shop sometime but I don't trust any of the ones around here but looks like im going to have to.
