Question about Nakamichi PA-2002 Car Audio Amplifier

1990 Lexus LS400 Nakamichi Car Stero Amp problems

I recently went to have my aftermarket system "professionaly" installed in my car and they car audio store told me that i had a problem with my amplifier for that system... that is not the amp i am asking about but shortly after they ran my wires and told of this, my sound for my radio started to cut out and then went out all together. If you turn the volume up all of the way you can faintly hear the radio. So anyways I took in back to the place to hear what they had to say and they said that my factory amp for the nakamichi premium sound system had quit working or gave out. Now I didnt value what they had to say fully because of the poor work they had done running the wires from my aftermarket system, but as i looked around on the web it seems that it is very possible that my facory amp could have just took a turn for the worse (it is 17 years old). So what i am asking is how do you test a 1990 Nakamichi car stereo amp to see if indeed that is the problem? I have decided not to take my car back to that car audio place all together because of the poor customer service along with the equally poor work they did. Any useful feedback would be greatly appreciated, seeing as how i dont have any tunes at the time. Thanks alot, Kyle.

    My sound went out today just as described. Normal operation for a while, then I heard a popping sound and the volume faded away. Now I have only a faint sound coming from the speakers at the rear of the car.

If the amp is damage it needs to be repaired or replace but the age of any amp doesn't matter, all are compatible to work.

Check Engine light comes on for Mass Air Flow Input, yet I recently installed a new sensor and new aftermarket intake, with no air leaks, so why does the light come up?

Try swapping with another MAF sensor at the parts store. If it was very cheap compared to prices of other auto parts store, then it may be very low quality and defective brand new. I've always been told not to use aftermarket intakes that use oil as the oil will get on the MAF wire over time and cause the sensor readings to be off.

Need to know how to install my deck in my 1999 chevy suburban

The best way to install an aftermarket stereo is to go to a stereo installation store and get the in dash "metra" kit and the wiring harness adapter that allows you to connect the aftermarket stereo wiring to the factory wiring on the truck...the "metra" kit adapts the aftermarket radio to fit into the space for your particualar vehicle..the tech at the stereo store will know what all this means if they know what they are doing...To clarify, "metra" is a brand name for these kits andthey also go by the name scoshe...

You don't mention what make of printer you have but all of the major brand name printer manufacturers have software support for their printers available for free download from their respective websites. Browse to your printer manufacturer web page and look for a "Support" link which is usually where you will find your printer software.

Blower motor or resistor?

If it was the motor that went out then it would not blow at all. The resistor is the culprit that starts killing off speeds. It should be about $25 to $30 at an aftermarket store like autozone or advanced auto parts.
