...popping sound coming from the tweets.

[scarab]

....there's this popping sound coming from the tweets. it pops or cracks once in a while (di naman tuloy tuloy). kaya minsan nagugulat ako at madalas naiirita.
...ano kaya yun? defective tweets, wiring, o sa amp kaya nanggagaleng?

...also, once i turn on the HU, there's this cracking sound bago tumunog yung music. this usually happens when i just turned on the ignition of my car, but if i turn off my HU tapos on uli, wala na yung parang garalgal na naririnig ko.

[ILuvDetailing]

process of elimination, check the wiring, if you have an extra set of tweets test it also, also check the RCA connections, etc.

[empy]

baka basag na...

[scarab]

baka basag na...

...wag naman sana (1 week pa lang yun saken, brand new ko binili). tsaka di naman siya parang continous popping sound. it'll pop once in awhile.

[Bravoexo]

poor grounding? was the ground wire tapped into a bolt or body but not sanded to bare metal? How's the signal coming from the HU? RCA? LOC?

[scarab]

...yun din ang hinala ng kaibigan ko eh. where do i locate that ground wire? sorry, medyo birhen pako sa mga audio eh. tinago kasi ng installer yung cables sa ilalim ng upholstery.

[pepengtom]

pop sound? try mo kabit relay.

[scarab]

....ano ba yung tinatawag na "clipping"?

[baurtwellXUV]

sa amp po yun sir, try mo yung wirings mo and yung sa ground mo sir...

[wren]

....ano ba yung tinatawag na "clipping"?

this is quite a mouthful...but it's the best definition of "clipping" i've seen so far.

Clipping

Amplifier distortion occurring when a high energy wave form (a very loud sound resulting in a large output) is input into an amplifier and the amplifier is unable to fully reproduce it due to power supply limitations or amplifier design limitations resulting in the audio output waves being cut off (the rounded tops sliced off resulting in short waves with flat tops). Clipping creates audible distortion and can be damaging to speakers especially if the clipping is hard and frequent.

Clipping generally occurs when an amplifier is playing at a high level and it is asked to output a large amplitude waveform (“tall” wave with lots of power). The amplifier clips when it does not have the power capability to correctly create the waveform. Instead, as the wave is built it hits a ceiling essentially not allowing the wave to go any higher. Since the amplifier cannot recreate the remaining portion of the wave rising above the “ceiling,” the wave is cut off.

Generally, the more power an amplifier has (especially relating to the quality of the amplifier’s power supply) the more immune it is to clipping. For this reason, larger amplifiers tend to provide better quality sound at loud listening levels since they clip less often (if at all) compared to similar but less powerful amplifiers.

Clipping may be heard in loudspeakers as an abnormal, non-musical sound. It is unpleasant and it may damage speakers (with tweeters being particularly susceptible). This occurs because a speaker cannot produce the flat-topped waveform sent to it by the clipping amplifier.

In order avoid clipping, do not play a sound system at excessively loud levels and make sure the amplifiers being used are large enough to recreate the sound levels in the given space. Generally, use the largest amplifiers reasonable, as they are less likely to clip and damage speakers. It is much more dangerous to clip loudspeakers by using a small amplifier lacking in power than to use a large amplifier even if that amplifier’s power ratings are greater than those recommended for a given speaker (distortion, and clipping in particular, causes damage not clean power from a quality amplifier).

....so could this be my problem? but jeff tan installed a 2 channel 300W amp just to power my seps (i think this already more than enough), yun nga lang luma na na nakatambak lang dun. also. its grounded to one of the bolts sa seat railing. is there a better part of the car to ground it? im afraid to dismantle the tweets altogether dahil baka di ko mabalik ng maayos.

[wren]

if you're running 300W, very unlikely ho na clipping yan, unless you have a defective amp. tsaka yung sound ho ng clipping is not "popping", it's usually "distorted" or "breaking-up" sounds.

[scarab]

....hmmmm, madala na nga sa shop before i invest in a better amp. tnx FXT for the input.

....what if i ditch the amp right now (til i get a better one), and let my HU (5750mp) do the work. mabibitin lang kaya ako sa tunog?

[ILuvDetailing]

scarab: re: grounding - it doesn't need to be bare metal, even a painted surface will do... make sure that its clean.

Don't ditch the amp, bitin na bitin yan, try taking off the tweeters and see how it sounds, if it doesn't have any problems then its not your amps, it could be the wiring. Also check the gain settings it might be too high. Good luck

[afrasay]

try to swap a good amp to yours. sabi mo nakatambak na yun amp mo so i suppose i was not use for a lng time. my best bet is that there are some leaking capacitors in the amp.

[scarab]

....actually im in the hunt for a good 2nd hand SQ amp kaso sobrang limited budge ko. anywayz, someone told me a bad amp may ruin my seps; is it also true that it may also eventually damage my HU? medyo dun ako natakot eh.

[scarab]

....mga bro! ganun pa rin after switching the tweets nag-pa-pop pa rin sa left side (so di tweets problema). minsan biglang lalakas pa tunog.

....checked the RCA connectors, ok naman. wirings seem to be clean and connected well sa passive xover. sa amp na kaya yun?

....arggghh! sarap pa naman pakinggan yung bagong CD ni anton ramos (sisters of the sun) pag SQ kaso that sudden popping is annoying!

[ILuvDetailing]

Its either the tweets or the Amp. Try to borrow an amplifier from a friend and test it.
