ang trouble is wala ng output sa speakers... una parang akala ko eh speakers ang problem since kapag lumulubak eh biglang nawawala tunog.. at pag lubag uli eh meron na uli...
The cheapest course is to use a voltmeter to check wiring first before looking for professional help.
If you checked out all the connections it's possible that a cable has a cut in the middle, you can use a voltmeter to check out the intergrity of the wires and connections.
If you don't want to DIY the repair most of the electrician will tell you that the problem has to be consitent for them to catch it. (mga tamad sila)
actually na trouble shoot na.. nagpalit na nga ako ng bagong amp.. the old amp (taken offline) was proven na defective na... yung akala kong speaker problem, now with the new amp eh lakas pa pala at i'm using it as full range kaya okay na okay...
i was just thinking to have the old amp repaired.. gusto ko talaga gamitin yun sa car na to...
dinala ko kanina sa perfect circle.. tinanggihan hehe.. fake alpine daw yun.. taiwan lang daw.. itinuro ako sa philsales... and okay na trouble shoot na.. iniwan ko na dun.... hopefully maayos nga sya...
