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.

The radio code is a security feature that's meant to deter theft, and it's unique to each vehicle. If you've lost your code, you'll need to contact a Nissan dealership or service center and provide proof of ownership. They should be able to help you retrieve the code. Please do not attempt to use codes from the internet as incorrect attempts may lock your radio.

I have the same radio now with no Bluetooth am trying to get Bluetooth on it too without having to buy another radio. Please help.

First thing to do is check to make sure that the batteries are properly charged.

Second, make sure that you have a clear line-of-site to the IR transmitter. Infrared (IR) works the same way that your TVs remote control works - if the signal is blocked, then you will not hear any sound.

Third, make sure that you are in the rear seat of the vehicle when listening to the sound. The IR transmitter only transmits to the rear seat, so you will not hear any sound if you are sitting in the front seats. This is a common problem that i see.

Lastly, make sure that the heapdhones you purchased are compatible with your 2006 2007 2008 2009 or 2010 Toyota Sienna. Remember that some older models require RF headphones, not IR headphones. I checked http://www.audiovideo2go.com for compatibility before I purchased my headphones. They have a useful listing of all the headphones and models of vehicles they are compatible with.
