first of all you should check the minimal impedance your amp handles , if is class d it should handle between 1-2 ohms total impedance in a mono conection , meaning whatever quantity of subs you have hooked to your amplifier,their total impedance should the minimum the amp handles that way all the power from your amplifier will be used.

SOURCE: i have two four ohm

Wire the kickers in parallel -- hook the positive from each speaker to the positive on the amp, and the negative from each speaker to the negative on the amp.

This will present a 2 ohm load to the amp, and it's rated down to 2 ohms.

sounds like you may have a bad torroid (the donut looking thing). you may also have a bad ground connection. make sure you have completely bare metal where the ground connection is. you need a very clean connection.

Amp and sub have been working great together then all of a sudden the amp is not putting out enough power to push the sub. MTX Thunder 311D


check to see if one of the RCA cables is unplugged or bad. check the gain check the sub level control on the deck if yours has one.

If you have proof of purchase(invoice or receipt) showing the purchase date and you are still within the warranty period then yes it would be repaired by MTX under the warranty guidlines, and by the way MTX is great at customer service and they are great to work with(very fair)!!!!
Keep in mind that the seal on the bottom of the amp cannot be broken or that will void warranty coverage.
Give them a call, you will be glad you did!

I am guessing the bass control is just a potentiometer that you plug in. It could be open and that is why the bass dies. As far as the switch goes, I am not familiar with the amp but it sounds like a crossover between low frequency and subsonic frequency.

Subs will go off the wall with bass, but not in tune with music.


hi, first disconnect the rca input, then switch on headunit and if the amp produces a constant bass thump it then means it has an internal fault. if the amp idles quietly then replace the rca cable, or try connecting the headunit lineout feed directly to the bass amp, in this way you cud find out if your fault is coming from the headunit or the equaliser. cheers
