With two amplifiers and a low output alternator it isn't uncommon to have the lights dim when the volume is up..

You are probably burning the alternators out because of the constant overload from the extra electrical draw of the additional components.

Most people that run a high output stereo will also run a high output alternator and a capacitor. The higher output alternator will keep up with the demand without overheating and the capacitor will clean up the supply so the voltage won't dip when the stereo is turned up and the bass hits.

The idle "kick up" (much like lock up) was a funtion of your computer which is no longer in use. It mainly worked with the A/C and power steering. You can turn the idle up a little manually to help this, I wouldn't go further than 800 in neutral being that your car has a tight torque converter to avoid the car slamming into gear and trying to "drive itself" without your foot on the gas.
