Question about Alpine PDX-1.600 Car Audio Amplifier
I have the service manual for the PDX 1.1000 model, but the designs are slightly different, more then just bigger components.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

This is a sign the you have poor voltage regulation. Which may mean that you are taxing the electrical system of your vehicle. I would suggest you adding a secondary electrical supply for you audio system. This can be done by adding an extra alternator and voltage regulator and battery supply. This will allow you to drive your audio system without having it (power supply) split between the vehicle and the audio system. The fact is your system is drawing to much current for the unit and your vehicle. You are blowing the 20-amp fuses which means the the amp is creating a currnet draw which is past the rated value of the fuses, which if done too many times could damage the power amp components in the unit. I would also check the ohmage reating on the speakers connect to the unit since you may have the wrong impedance which may also cause excessive current draw and actuate some sort of overcurrent protection.

Ot two issues, First the AMP is going into a protection mode this means that it is drawing too much current. As netrecov said you need a capacitor, this will oppose the rapid current draw, by allowing the voltage to remain constant. However I would also sugget that you rewire the setup to manufatures specification and make sure that all grounds and supply leads are installed properly. Taking into mind the the 4awg wire has less cross sectional surface than the 2 or 0 AWG wire causing it to have more resistance this is power loss in this case (follow the specifications).
I hope this helps

You are going to want to make sure all your power wires and grounds are 4 gauge as well as the wire leads to and from the capacitor-4 gauge also. make sure you have a very good ground - the power wire from the battery should hit a distribution block-from the dist. block a 4 gauge should go to the capacitor another 4 gauge to the mono amp and another to the 4 channel amp -every component should have a good solid ground even if you have to bust out a grinder and a drill and some self tapping sheet metal screws and go nuts on it- see if that helps you
