20 Most Recent Alphasonik PMA1800A Car Audio Amplifier Questions & Answers


It could be a problem with the head units remote wire (blue wire) that connects to the amp. It turns on the amp when the head unit is turned on, Check that wire for 12+ volts when head unit is on.

Be sure the amp is properly grounded,and the input and output signal (speaker) wires are connected.

You could also use a temp. jumper wire at the amp by jumping the power and remote terminals, just to see if the amp works.

Note: Do not leave the temp. jumper in place, amps are not meant to be continuously powered up. Make sure it is in a well ventilated area so as to disperse its heat.

Good luck

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?

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.

My car (2005 Honda CRV) was shipped overseas and the radio asked for a code. After several tries, I searched the internet for a solution. Apparently Honda now allows you to obtain the code through their provided website. You will need the VIN #, the phone number and zip code that is on file when you purchased the car. Our car was purchased used and did not come with a manual. When I went to enter the code in I had already entered too many tries, now it reads ERROR E.

However, even before having the code (as well as now that it reads ERROR E) I can get the radio working. Push in preset buttons 1 and 6 and push in the power button simultaneously. A long number appears - at that point I pushed preset button 2 and the radio operated normally. Unfortunately, I do need to do this each time I turn the radio on.

The Q factor does have to do with tones and pitches of your music. This determines a Quality factor of how pitches are placed (high tones, low tones, and mid tones) and using the Q factor will use a preset setting to put the tones at a high proformance audio.

Simple test and trick for you.

  1. Put in your favorite cd.
  2. Turn on the Q factor
  3. Play a song and listen to it for atleast 45 seconds
  4. turn off the Q factot
  5. Play that same song for atleast 45 seconds
  6. Now you determine if the quality used by the Q factor is better or worse

For some songs that have close pitch audio, it may not be as noticeable, so you can repeat and test. Give it a try, because then you can understand it more by hearing then reading. Its all about how you want it to sound. Good luck

Thank You
