20 Most Recent Alphasonik PMA600HC Car Audio Amplifier Questions & Answers


Most amps come with a soft start up that illiminates this problem... Im guessing that your amp does not have this feature and thats why you hear it. Read the manual and see if it states anythign about this.

you will want to turn your radio volume up till you hear distortion then trun it down slightly. then turn your amp up until you hear distortion then trun you amp down slightly.

hi first disconnect all spks, then turn on the amp. if amp power lite stays on bright then proceed to connect one speaker or sub to the amp. if the amp lite dims during any spk connections then it may be that the spk is faulty or there is a DC voltage (dc offset) emitting thru that particular channel. also check all spk impedance before reconnecting them to the amp. cheers.

Have you tried to hook up another sub (spk) to the amp? Or just wire it to a stereo to see if it works? single voice coil or dual?

Your manual should have all info inside.

Generally speaking if the voice coil is actually 'blown' (accepted too much power therefore reads as a short when connected to an ohmmeter) It would be cheaper to purchase a new sub woofer.

90% of the speaker manufacturing price is in the voice coil. The cage, driver and dustcap as well as the surround are inexpensive components.

I would suggest testing the voice coil with an ohmmeter first before you decide what to do. If the meter doesn't read a short then its likely a TV repair shop can reconnect the lead that attaches the terminal to the voice coil.
