I have a PDX 1000.1 and it keeps shutting down on the low notes when I am rocking out....I have the gain set at around 75% on two memphis shallow dual 4 ohm subs wired so that it is a 4 ohm load....worked fine for a couple of weeks now it just started messing up...anything PDX owners can think off?

Sounds like an installation issue.
If it was a install problem if i just swapped out the amp with a TMA 500 would it work because it does....I don't know if I just bought a bad one I got it from a local dealer so I have a warranty man I should have just got a JL amp!!!
Also the memphis subs are great maybe just a hair under the JL's but over half the price

Wouldn't matter?
From what I remember the PDX is stable at 1ohm, and puts out regulated power of 1000 watts no matter what ohm configuration.
Stable down to 2 ohms... http://vault.alpine-usa.com/products/documents/PDX-1.1000 OM.PDF
OK quick update....
Went to the shop that it was purchased from they bench tested and stated that it worked because it pushed the little 5 inch speaker they attached to the amp....I said o' yea then install it back in my truck and thank you for checking it for me...The installer came back within 5 minutes and asked me what was it doing again so I told him...He told the manager yea that is what it happening when the bass hits sometimes it will play it, sometimes not, and sometimes turns off all the way (no power lights at all)...Double check all wires and everything was up to speed...Subs wired correctly, Power, Ground, Remote wire, RCA's....
Shop agreed to send it back to alpine now just waiting to see how long the turn around time is gonna be....I dont know if I bought a faulty one or if the owner just scammed me I only paid 395.00 for it brand new in the box from an authorized Alpine Dealer but have had battles with it since day one..I really hope that Alpine is able to fix it I like the size and power when it does work...

Maybe you should actually listen to the PM i sent you...
The amp shuts off because your charging system isnt supplying enough power to the amp so the amp goes into protect. I had the same amp, same problem and found multiple, multiple similar cases with the same situation, same amp. Get a better battery and do the big 3 upgrade if necessary to fix the problem.

Maybe not the big 3, but a better battery should definitely help
What is the big three exactly? Battery, Alternator and ?

ground,
Yeah i don't believe you killed an pdx 1000
you only paid 400 for a pdx 1000 ??? dude their 800 new, are you sure thats real ?????
on a side note
Isn't the pdx tested and rated at 11.8 volts ? so it should be stable, unless you **** stuff dips below 10 volts and you would really notice that
