Alpine amp not working.

I have two alpine pdx-1.1000s that just stopped working in the middle of a song. the fuses in the amps are all good. the light on the top is on. the fuse in my 0 gauge wiring kit is also good. i checked all the rca cables behind the cd player and going in to the amps. i know a lot about car audio and this has me stumped. did something burn up in side the amp?

Disconnect all speaker leads from the PDXf4 - test. If the amp turns on and says on ok - then turn off, and attach one speaker lead at a time until it turns off. When it does check that speaker and the speaker wire to see if it is blown, shorted out etc.

PDX 1.1000 amp overheating?


Hello thefatman69e,

The Alpine PDX-1.1000 is a physically small amp to produce the power that it does. The result is that it has less physical area for heat to dissipate. Running at or near it's maximum output into a 2 ohm load, it needs some serious airflow to keep it cooled down. I'd look for some way to get more air to it.

Hope this helps.

Alpine pdx 1.000 keeps cutting out


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

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.
