Also check to make sure that your RCA interconnects are good. If you are using interconnects that have a screw on top piece, make sure that they are all tight. This can induce all kinds of noise.

My mtx thunder 1501d car amp making noise in the subwoofers

This is common with pioneer head units, the rca jacks are not properly grounded and this lets engine noise come through the rcs cables. This thread explains a fix http://www.caraudio.com/forum/showthread.php?t=337644.

Makeing poping noise

Although open shields on the head unit generally cause MTX amps to squeal, it can sometimes cause the symptoms you described. To check the shields, you will need a multimeter. The procedure is on the following page:

Testing for Open Shields on RCA Signal Cables

If the shileds are OK, we will have to check a few other things.

if your power light is on then check your preamps (sub out from head-unit).Maybe you need to turn on that output thru head unit's audio menu.Also when using dual voice coils if you wire them out of phase there will be no output

Mtx 1501d no sound

There are a number of things that can cause it to act as you described. Have you pulled the covers off of it yet to see if you can see any problems?

If you do, disconnect power from it and don't touch ANYTHING on the board when ANY of the 3 LEDs (2 are not visible from the outside) are lit.

Hi i have a mtx 1501 d

If it does it with no RCAs plugged in, the speakers or wiring need to be checked.

If the speakers and wiring are OK, the amp may have shorted output transistors.
