Most likely the ohm load is too low, if you have the subs wired in parallel rewire them in series and see if that resolves the problem. if not then you do not have enough battery power to support the draw that the amplifier pulls. if the vehicles voltage drops below 11.5 volts the amplifier will momentarily shut off, similar to how the lights in your house dim when the a/c cuts on due to the sudden power draw. hope this helps. p.s. if you cant afford another battery right away, lowering the crossover frequency to around 65hz will greatly reduce the amount of current necessary to keep the amp pumping. (in my opinion it sound better that way anyhow.)

Rewire your stereo cables as such:

Red- positive - battery
Black - ground - chassis
Remote (Yellow) - ignition switch

The "LINE OUT" should go to your SUB-WOOFER.

The while-lined wires paired with the solid colored wires are either your Front LR and/or Rear L/R.

2 MTX Thunder Problem.. Bridging?


Is there a option on the chanels that say ''Bridged''? If so, you can hook the subs up in parellel or series to get different ohm loads. Usually the lower ohms, the more power amp puts out. Those subs can handle 225 watts RMS whitch means the power it can handle constantly. If the amp gives more than 225 watts RMs, you could be at risk of blowing the sub. If you could give me the model # of the amp, I can be of more help.

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 have 4 MTX 10s and a JL 1400D amp and it cuts off if i turn it up to bang it what do i do


How do you have the subs wired and what impedance are they? Your amp is only stable to 2ohms. If they are 4ohm drivers, 2 have to be series & 2 have to be parallel. If their 8ohm drivers, parallel is fine. If your not sure, add a comment to this post with the model numbers on your subs and I will get you the correct info needed to do it right.

My subwoofer doesnt work


you mean that the SUBWOOFERS connected to the amp cuts off and come back on randomly?? did you bring the SUBS level to a high volume ? i suggest to check first the value of the speaker (ex. 4 , 8 , 16 ohms ) matches the same value with the amp . second , hows the subs connected , in series ? or parallel . you will need a multimeter for this task .
