Amp makes subs pop

OK this is something i've never encountered. I just recently sold my box so i put my subs in a new box. everything was working good for about a minute once it was all set up, all the sudden after a minute the subs just started popping, no music coming out of them, they were just popping constantly. They keep popping even when the volume on the head unit is at 0. and when i turn it up the popping stays at the same level. If i disconnect the rca's they keep popping but if i disconnect the speaker wires then they stop. I checked the grounds, all wires, fuse and all that sh*t, i have no idea what it can be. When i start the car, the lights dim a little when the amp turns on then the subs just keep popping constantly, and the amp isnt going into protect or anything. I know for a fact my subs are not blown i had a lot of people check that out, no one knows whats wrong. My subs are two 12" Kicker L7's and amp is 2500 watt Orion

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.

After 7 yrs of use, it just stopped working

I agree that It could be one of the other reasons listed here.....

But, I had the same problem with a 1,000 watt Kenwood amplifier and it worked like a boss for the whole two years that I had it and then one day the box that I had my subs in somehow came apart and after I changed out boxes the amp quit working. It came on but it wouldn't work anymore except for when I turned it a certain way or sat it against something.. Anyway it ended up being a loose female port plug on the inside where the auxilary cables plug up.

Hope it helps.

I recently hooked up a new kenwood deck put new front and back speakers in. I hooked up a 1200 watt hifonics amp about to plug in my 2 15 inch rockford fosgate speakers rfz1412 and they dont play. All the...

Ok, so I am assuming that the other speakers are working, and it's just the subs that are not, right? If this is the case, start from the source. Make sure the RCA cables are plugged in and not crimped anywhere. Then to the amp, Did you check the gain levels on your amp. That is the knob next to the RCA input on the amp. Also, check the wiring to the subs. Make sure all your + are goinig to +. Sometimes in the "heat" of a good install, you just lose track of those things. When in doubt. Undo all your wiring and start from scratch. Good luck.

I have a fairly good sound system in my jeep cherokee, new speakers, deck, new battery, rca cables, and a new box for my subs. But recently i've been dealing with some problems. i've had my amp grounded...

there are really only 2 causes for this.

  1. grounds. Make sure the grounds are clean and tight and all paint and dirt was removed before they were fastened.
  2. Your alternator is starting to go bad.
I would lean toward the grounding problem as you have said you just changed them. Also make sure the grounds are as short as possible.

Rockford sub squeaks

Hello markwasicki,

You did not specify what type of enclosure the subs are in or if they share the same airspace. But the sound you describe sounds suspiciously like the enclosure is at fault and not the sub itself.

Remove and reverse the subs in the box and test for the noise again. If the noise is still produced on the same side of the box, it's the enclosure. If the noise follows the sub, then you have a problem with that sub.

If the box is making the noise, and it's a ported box, you probably have "port noise". If it's a sealed enclosure, you could have either an air leak or flexing noise. In either case, repair the enclosure or put the subs in a new one. If the sub itself is making the noise, there probably isn't much you can do. Most likely some part of the voice coil assembly is touching where it should not.

Hope this helps.

Popping sound! please help - jl 500/1 and two jl w3v3 2ohm subs

no connection are good + to + -to - thats all that matters. either the speakers are blown or you need a stronger amp. since you already tried speakers probably need bigger amp. definitley not the box. no such thing as a break in period, are the subs 10 12 inch or what. you could try to bridge them too that means hook both up to the same +-terminals, 2 wires per screw. it usually isnt the way they hook them up, its the wires fuses etc that cause problems. what guage wires is the speaker wire, the power line etc. if you give me these guages i might be able to get somewere

KAC-9102d no sound, Amp powers on but no sound to the subs.

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...

My amp wont power both subs the same

you most likely mess up you wiring... im not sure what ohm resistance your subs are, but if its 2ohm or 4ohm you wire straight foreward one sub all positive wires to left positive, all negitive to left negitive, and the same with sub 2 to the right terminal. BUT if your subs are 8ohm then wire it with all positives from both subs to LEFT positive and wire all negitive wires to RIGHT negitive... and see if that helps and good luck!

Cerwin Vega ve-28s subwoofer and new Cervin Vega 2-way satellites

I bought my VE-28s and it did exactly that crackled, cerwin replaced part in amp but few months later problem persisted. they then replaced entire amp assembly and its been fine. i really push it to and its been fine. to test it, unplug the connection from amp/ reciever and see if it persists. if so its the sub, if not its the amp/ reciever. dont dump it, these subs really crank and can put out some deep loud bass.

Amp is on, Subwoofer works, but no sound.

here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem
