SOURCE: When i have the stereo on radio my amp/subs work

use the blue/white wire (amplifier remote turn on) instead of the blue wire (power antenna remote turn on) to turn your amp on. the power antenna wire shuts off when leaving tuner mode.

I have a stock stereo and two subs with an amp in the trunk. Also two alpine speakers in the rear. Whenever I turn my balance to the left my subs don't play. What's wrong?
Hello.... I am sorry to hear you are having problems. The reason for this is that since you have a stock stereo, the shop (or person) whom installed the amp and subs used a line out converter. What this part does is allows the connection of RCA cables to the factory head unit. Almost all bass signals are always in stereo, so since you were only hooking an amplifier for just subs, you can actually just connect to just one of the rear speakers instead of connecting to the right and left. Just makes the install a little quicker. There is nothing wrong with this as I usually do the same thing in our shop. However, if you are going to be using the balance control, then you will need to go back to the shop and have them hook the converter up in stereo (to both rear speakers). Hope this helps!

I installed the amp and the light is on but no sound from speakers. i've checked everything i can think of. any other ideas?
There are several things that you can check for this issue:

Check that the remote turn on wire is connected.
Check that the RCAs from the stereo are connected at both the amp and the sub output of the stereo.
Check the stereo; some head units have settings for the sub output. You made need to set the sub output to "on" at the stereo.
If your subs/speakers are in a box, check the connections there.

I have hooked up my subwoofer and amp to my factory stereo in a 2011 camry. My power wire is hooked directly up to my battery, my ground to the chassis and my remote to my fuse. I have my RCA wires (RCA on...
Rewire your stereo cables as such:

Red- positive - battery
Black - ground - chassis
Remote (Yellow) - ignition switch

The "LINE OUT" should go to your SUB-WOOFER.

The while-lined wires paired with the solid colored wires are either your Front LR and/or Rear L/R.

I get a pop from the sub when the power comes on.
This is caused because the stereo you have put in, is a high power output, or higher than the factory and puts that extra power into the factory amp systems causing the amp to surge the power to the speaker resulting in the pop sound,most newer cars use a stereo system without an internal amp so as to reduce heat and a external amp in usually under a seat or dash and a high power stereo boost the output of the amp.

No sub signal from a CDX GT520.
connect the speake(sub) directly to the stereo(just use one of the rear 6x9 speaker wire to test the sub and make sure it's not the amp. if it does not work, it's the sub

Installing PA5422 in two channewl mode
Since your first paragraph is leading to your question paragraph, I'll adress that. "what is the difference amongst the MONO/STEREO/L+R switch options available on both Front and Rear AMP X-over Sections of the PA5422?" Mono is same sound output on each channel, stereo is what you want as it gives out stereo sound, and L+R is most likely blending the channels together.
