amp putting out low power

Are you certain the signal to the amp is still strong?

To be clear, was the system working OK one minute than "got quieter" the next?  Or did you change amps and that caused the change?

If the former, you have a defective amp (power supply or output feedback regulation circuit is a guess.)  If the later, you need to setup the input gain on the new amp properly, you have a defect in the speakers or wiring, the new amp is bad, or you are simply noticing the different output of a different amp.

the problem occured as soon as the new amp was installed...the gains were not the problem as it still occured weather gains were all the way down, all the way up or somewhere in between. speaker and wiring should not be the issue because worked properly with original amp and i checked wiring after new amp was in also....is there repair shops in the montgomery county, maryland area that are rockford certified that i can have it repair at and possibly tweaked at?

Well, there may or may not be a problem since this is a new amp, but it could certainly be an out-of-the-box defect.  I suggest getting the amp checked out.  Take it back where you bought it and make sure it is OK.

Sounds like yet another victim of the "i wanna save a few bucks on ebay" syndrome.  In my experience, you'll get a few good deals out of ebay if your lucky, then get shafted.  Making up all the money you saved on the last few purchases with that piece of crap that just arrived Fed-Ex to your door.  Oh, and you don’t have a warranty on that other stuff you bought either!  Hope nothing goes wrong.

Go to the Rockford website and look up local repair centers.  Chances are its not worth repairing.
