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

The most likely suspect would be an internal fault on the Alpine PDX-1.1000. So other than verify the 2 ohms per speaker using a continuity tester (DVM / VOM), all others involve opening the Alpine amp to effect repairs.
Options then are: to consider a DIY (do-it-yourself) repair if and only if you're very familiar with electronic components & circuitry, use of a DVM/VOM and a soldering iron/station.
Access to a Service Manual or at the very least, a schematic diagram would be a necessity (although a challenge in itself) as detailed procedures, test points diagnosis flowchart would be outlined though should you be uncomfortable with a DIY, perhaps your best bet would then be to seek the services of an authorized Alpine Service Center (specially if still under warranty) or a qualified professional.

"1. Does your amp have a high input port? This is where instead of RCA's you feed it speaker output from your head unit? 2 If so try this and see if the magic happens.. If it doesn't your screwed and the problem is internal most likely in the input stage and that's why your having to "fool" the amp.
3. Also take off the remote turn on wire and make a short little jumper from the remote turn on to the B+ on the amp. Yeah the amp will blaze on but see if it changes the output."

SOURCE: IS the alpine 3552 any good?
alpine makes amaizing amps... as long as it's matched to the speakers/subs you are going to put on it this amp will last you a very long time... and it will put out amazing power... you won't be disappointed.
