Popping sound, but sub is fine, maybe wiring???

[verojie]

HI guys I need some help, Ive just set up my sub recently and it has started to make a really unattractive popping noise and it doesn't seem like it should do that.

I have a boss phantom P156DVC

http://www.bossaudio.com/auto/car-audio-sound-system-auto-stereo-dual-voice-coil-subwoofer-boss-audio-p156dvc/#p-specs

Subwoofer Basics Subwoofer Size 15"" Subwoofer Type Component Total Power Output 2500 Watts RMS Power 1250 Watts @ 4 Ohms Frequency Response: 25 Hz to 1000 KHz

And a boss audio r2000m amp

Max Power Ratings Total Power 2000 Watts Max Power @ 2 Ohms 2000 Watts x 1

RMS Power Ratings RMS Power @ 4 Ohms 500 Watts x 1

I have wired it like this

I have a feeling I have done something wrong, even on the amp I put all the setting on minimum then slowly put them up and it eventually gets to a point where it starts making that noise and they are not on max. Please help me out guys. thanks

Your clipping the living hell out of your sub/amp. What did u use to set the gains? Is bass boost off? Pics of said amp setting would be helpful. When I was curious once I cranked all my amp setting to see what would happen to a sub/amp combo I was ok with blowing, same thing. Disgusting popping noises, sub (dual brand) blew within 3 seconds.

shit, how am i meant to not do this "clipping", is this when its overpowered

[MaxVolume]

first step is a good tuning, for that you need a dd-1 or an oscilloscope. if those aren't available its best to play safe and keep your gain low. Might want to do a bit more reading and research, google can be your best friend when starting out.

Yeah sounds like bad clipping

clip clip city bich clip clip....

I've seen this many times.

the issue your having ( mostly your amp) you think you have a 2000w amp and want it to sound like a 2000w amp. in no world will that amp do 2000w... ever! don't mean to seem like a jerk but its a crap amp.

you keep turning your gain and bass boost up to make it loud. but that amp won't do it. so instead of you getting the deep powerful bass you want, you get a terrible popping.sound.

also your wires prolly aren't big enough to support a "2000w" amp anyway.

what gage wire are you using for power and ground?

also a better ground could help.

in short your not gonna get what you want from that amp. I'm sorry i truly am, we always try to tell people to stay away from boss, dual, sdx, xplod, Pyle, crunch, audio pipe... the list goes on.

when you see a good brand like dc audio and there 2000w amp is $600 and the boss 2000w amp is $96 it's not that dc is trying to rip you off or just charge whatever they want! it's that there amp on the correct.wiring will do that 2000w plus some! while that boss amp is lucky if it puts out 500w of good clean power!

sorry if i seem rude or mean, this is the truth!

turn your bass boost off and don't turn your gain more then 1/4 of the way up. that's the only way your not gonna Fry your amp and kill.your sub.

i know what your thinking "but it's not Loud with the gain only 1/4 of the way up"

but that's what the amp is safe at.

that amp has 60 amps of fusing. itll do like 500w. if it doesnt sound loud, its because you're expecting 2000w but you're getting 1/4 of that.

if it a hollow pop noise you may be bottoming out your voice coil or the triple joint has broken/ripped.

amp sucks too.
