I just install my new setup ,i have 1 pdx f4 ,1 pdx m12 and 2 sub 10''type r and my pproblems is when i put a song the pdx f4 lights become red and my mid and tweeter cut ...

1.take it back to who installed it and ask them to do it right. 2.your sub may be wired incorrectly 3.your sub may be cooked.

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.

ur speakers are probably connected wrong so diconected and and connected differently. and if ur speakers a dual coil see if they connected it if not do this. only if ur speaker is double coil meanin if ur speaker has 4 connections for speaker wire. and if it does than connect possitve to negative from one coil to another and negative to positive from the other one than from one of the coils connect the wires going to ur amp positiv to positiv and negative to negative bringind the sub to 2ohm constant
try that see if it works. only if u have a double coil subs

system not configurate properly go to a pro and let them do for you you have good equipment just need to put together rite.for wht you have you can get better sound than that,,good luck

1. check your B+ wire and make sure the fuse is good, and your ground wire and are you certain that the remote turn on is good?
2. If you have 3 subs runninng on the amp i hope those subs are 8ohms and you wired them in parelell to give an impedance of 2ohms. Let me know. Mark @ Sounds Good to Me.. tempe, az

well you would have to look into the ohms of the amp compared to the ohms of the speaker. If the ohms are different you would have to hook them up in a different way. check the RMS on the speaker as well as the amp, this can also be sufficed by wiring it different if ohms match up properly! Hope this helps you out and if this is not the case let me know.

He may be right! You might try finding a new source of contact for your ground cause it may not be sufficent enough to ground to, also make sure that no wires from the back of your radio have any wires sticking out touching other interfering things that could possibly be causing the noise

what is happening is the amp can draw the current. u need a capacitor

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.

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.
