These subs are dual voice coil I'm sure...make sure they are putting a 2 ohm load on the amp total, and also set your gain and frequency setting right. Set the frequency around 85 or 90, make sure the lo pass filter is on. Turn the gain ALL the way down and turn your stereo to the point right before your speakers distort....then slowly increase the gain until the subs are playing at full volume. This should not even be close to all the way up, and the subs should sound accurate and bold. Turning them past this point will cause distortion, in which case you should back off the gain a bit. Distortion causes power to cycle through the amp very rapidly and can cause blown subs and blown fuses. If you do not know how to wire both subs for a combined load of 2 ohms, please let me know what type of subs you have.

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.

straight up. Since it has the power saving technology where it gives out the same power at 2 ohm and 4 ohm loads then u dont have to bridge it and since its a single speaker you dont have to bridge it and since it is a mono block oyu dont have to bridge it. just wire + to + and - to -.

SOURCE: 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

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.

I just purchased and had installed an alpine pdx-1.1000 amp. powering 2 12" jbl's. while the owner was demonstrating this to me, we had it going loud, and it blew its 4 fuses. once he replaced the fuses,...


Technically, the manual says the amp should have 20A fuses, so by putting 25A fuses in, you've allowed more current to get to the amp before the fuses blow than recommended. I'd be more concerned about why the amp is blowing fuses.

If the subs are single 4 ohm voice coils and wired in parallel, you're fine. If they're dual 4 ohm voice coils, and everything (subs and voice coils) are in parallel, you're putting a 1 ohm load on the amp, which it's not rated for.
