i think subs only produce the bass (boom boom boom sound) and no music

sa speakers na lang nalabas yung sound/music pati mini basses

nawala ba yung bayo?

sir hindi kaya nasira na mismo yung subs? over played ba? try connecting another set of subs muna or check kung may power sa wire ng sub to be sure.

tama si archie, gamitan mo ng tester kung ano yung output nung ampli mo kung tama pa ba nilalabas.

alam ko may continuity ang speakers... well sinubukan ko na sa ibang channel using different wire... still wala pa din po nangyari... could be the subs and problem na kase kahit parang jerk sa cone wala eh... sayang naman 6 months palang yung sub.. nererepair ba yun?

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.
