No sound on sub

[ruelsdcz]

sir, check the PIGTAIL. un ung wire na copper from connector to your subwoofer cone. COLD SOLDER po ang tawag doon, though visually nakikita mo nakadikit cya but sa connectors and subs cone mo mahina ang contact nya. all you hv to do is to heat it up will soldering iron kung marunong ka if not baka masunog mo ung surface ng cone.

sir, im having problem with my sub... kahapon kase nung nagplay ako ng music bigla nalang ayaw tumunog ng sub ko pero yung front and all meron. i check yung sa channel ng amp. eh may supply naman po. paano po ba magtroubleshoot ng ganito na case and ano kaya ang cause?

Sir pls. check the possible caused:

1) Check mo yung audio aux. in sa sub mo kong may audio signal sya coming from the Head unit, kong wala pls. check the connection bet. Head Unit ( Car Stereo) at sa sub mo.
2) Check kong may power ang Sub, kong wala check the fused.
3) Check mo kong ok pa ang mga spkrs. ng Sub mo, spkr. coil, pigtail connection etc. or yong connection mismo ng spkr. at Sub.
4) kong OK ang connection at may audio signal from Head Unit to Aux. In ng Sub mo at wala parin audio signal sa main spkr. ng Sub mo, ang possible caused nyan may problema ang Amplifier ng Sub mo, kailangan mo ng technician to troubleshoot.
Yun lang ang ma advice ko, God bless!

Check your RCA's cable if the slipped and the 12 volt turn on line. Some amps will report as "powered on" but do not have voltage on the remote line and therefore won't do anything. If you have a digital multi-meter(DMM), Disconnect your sub from the amp and set your DMM to Ohm's. Place the leads on the + and - of your speaker, you should have a reading anywhere from 1 to 8 Ohm's (depending on the number of coils and their resistance). If you get 0.00 or a fluctuating reading, your coil might be burned out. Again, check RCA connections and remote line at the radio and amp. If you have a buddy with a system, borrow his/her sub and hook it up. Check to see if your amp has a light marked "Protection Circuit" and is it on?


Or MAYBE, Just MAYBE your neighbors got tired of you blasting your tunes all the time and disturbing the peace and quiet in the neighborhood so one of them broke into your car and sabotaged it.

nag try ako kunin resistance kanina... sa dulo ng pole yung may clip wala reading na makuha... pero after ng hinang dun mismo sa wire meron na 4 ohms... sinilip ko sa negative na pole mapuputol na yung pagkakahinang mga 3 strands nalang nakakapit! pwede ba derecho hinang ng 40W na soldering iron un? hindi naman heat sensitive?

mga sir saken may intermitent ung bayo ng subs ko... may power naman then may lumalabas na sound pero ung lakas ng bayo nawawala. ok naman wirings at power. Im using NBN subwoofer ganito ung itsura http://www.sulit.com.ph/index.php/vi...uploadedImages

nagoogle ko lang ung picture hehehe.... thanks mga master

[danieyoyo]

ok na mga sir napagana ko na, hinang lang katapat dun sa negative na terminal and add na din ng konti pang lead sa kabila for sure... hirap lang ng konti kase hinihila ng magnet soldering iron ko. hehehe..

maraming salamat

sir next time palitan mo na kci hindi din tatagal yan pagbumayo ng malakas na sunod sunod. what i did is i replace it na medyo mahaba so malaki ang play nya hindi pwersado ung pigtail.
