Need Service Manual for Alpine PDX 1.600

I have the service manual for the PDX 1.1000 model, but the designs are slightly different, more then just bigger components.

SOURCE: Blown fuses

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.

According to the manual, the issue could be:

  • Internal issue with the amp circuitry.
  • A short on the speaker output(s).
  • Power source voltage is too high (aka above 14.5V).
  • Overheating.
The easiest thing to do is to try removing the connections to the speakers at the amp and see if the issue disappears after each set has been disconnected. Keep removing wires until both LEDs stay blue.

Hello Briankt69,

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

Thank you,

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

How do you bridge an Alpine PDX amp


you have 2 + and 2- right? twine both speaker wires together. like + to + and - to - and then pick only 1+ and 1- to hook up and then you should double the power to the speakers only

I have a alpine pdx 1.1000 and it is in protect mode so i disconnected it i started to hook it back up and put power to it and it gose right to protect mode anyway to get it out of protect mode


The most likely suspect would be an internal fault on the Alpine PDX-1.1000. So other than verify the 2 ohms per speaker using a continuity tester (DVM / VOM), all others involve opening the Alpine amp to effect repairs.
Options then are: to consider a DIY (do-it-yourself) repair if and only if you're very familiar with electronic components & circuitry, use of a DVM/VOM and a soldering iron/station.
Access to a Service Manual or at the very least, a schematic diagram would be a necessity (although a challenge in itself) as detailed procedures, test points diagnosis flowchart would be outlined though should you be uncomfortable with a DIY, perhaps your best bet would then be to seek the services of an authorized Alpine Service Center (specially if still under warranty) or a qualified professional.
Now referring to http://www.fixya.com/support/t1817194-stuck_in_protect_mode_phoenix_gold_ryval

"1. Does your amp have a high input port? This is where instead of RCA's you feed it speaker output from your head unit?
2 If so try this and see if the magic happens.. If it doesn't your screwed and the problem is internal most likely in the input stage and that's why your having to "fool" the amp.
3. Also take off the remote turn on wire and make a short little jumper from the remote turn on to the B+ on the amp. Yeah the amp will blaze on but see if it changes the output."

My alpine clips out at high volume I took the subs out and hooked um up outside of the car and it was working fine. do I just have a short in a ire or is this the pdx 1000 safe mode. How can I get it fixed


Go to rockfordfosgate.com they have a woolfer wiring wizard that can help you make sure your amp is under the correct ohm load, if your woolfers are wiring up on a 1 ohm stable load the amp will overheat and go into protection mode and cut out.. Need the woolfers on a 2 or 4 ohm stable load, and the amp should run fine with a capacitor, and some good 0 to 2 guage cable, plus a good battery and alternator to feed it

you need more batt, more amps, try new batt, capacitors are paperweights, spend on good batt.

I have an Alpine CDA9884 the deck has been in my car for about 3mos and I've been listening to my speaker from the power put out by the deck itself. I have installed an Alpine PDX 4.100 and a PDX 1.600....


the manual says that you should power off the internal amp if using external amps. Maybe you need to do this to get power going through the remote turn on?

in the menu its "POWER IC ON" you need to change it to "POWER IC OFF"

hope this helps?

Alpine amp and subs questions


it will depend on how you use the 2 alpine subs,, do you know what there individual impedance is [ ohms ] and how you intend on wiring them,,,in series, in parallel, in any case you must maintain the min load in order to load the amplifier properly,,,otherwise the amplifier will operate improperly and allow DC [ direct current ] to pass and fry your subs...so what I really need is more in formation
