Question about Alpine PDX-1.1000 1000W x 1 Car Amplifier Car Audio Amplifier

1 Answer

Blown fuses I have an Alpine pdx 1.1000 pushing 2 Alpine 12" type R subs, and my power supply also feed an Alpine MRP-F450 for the front speakers. I have a 100 amp fuse at the battery using 4 gage wire to a Tsunami 2-farad cap then 8 gage to each amp. As I turn it up, the 4 20-amp fuses blow on the PDX 1.1000 amp. Also, my lights dim with the bass.

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.

Is it possible that you may have over driven the unit and blown either the power supply or output stages? Well, if the amp is getting power as you indicate the issue lies within the stages I just mentioned.

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.
