My alpine pdx 1.1000 amp cuts out, the sub cuts off and the amp goes in safe mode but it does it before it even gets loud, the sub is a 2000W rms sub, why dos the amp go in to safe mode, i cant turn the amp or anything

I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

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.

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

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.

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

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

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

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.

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.

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
