Question about MTX Thunder 1501D Car Audio Amplifier

2 Answers

Any ideas? I have a MTX 1501d. I have sufficient power source- 1/0 gauge wire and 2 farad Rockford Fosgate capacitor power. The amp powers on perfectly and produces sound, but only when frequency, EQ, and gain is turned all the way up, or at least halfway up. Even then, w/ all three 100% up, it only produces weak power- maybe a cpl hundred watts. Of course at that point, not only does it sound horrible, but it's nothing near as loud as it should be. When the frequency and EQ knobs are both all the way down... the gain doesn't provide any difference in power. With these three controls turned down, you only feel current going through subs, but no sound, and then when you get close to the halfway point of turning them all up, it kicks on somewhat, but never reaches full potential..... can anyone help please?!

Looking at the control panel on top of the amp you'll see three catagories; Gain Control, Processor, and Prizm EFX.

This should fix your problem:

Gain Control: Depress the button listed as Input Sens to x1 (this is the setting for line level input; x10 is for high level input). We had similar problems with an earlier class TA81002 amp. Another problem could be if you are using a head unit that has an onboard lowpass crossover, try turning the crossover off on the deck and use just the amps crossover.

Also are you sure that you don't have your subs wired out of phase with each other? This can cause a very similiar problem. Let me know if this doesn't work and I'll call an old friend at Mitek.

To charge a capacitor:

Mi lights dim everytime mi speakers beat


simple issue means your alternator is not able to supply enough amps to keep the system running properly, recommendation get a capacitor to handle the extra load, it acts like a second battery, when the alternator charges the cap it takes the load off the cap rather then the battery, so the lights and system all run with sufficient power i recommend a 1 to 2 farad capacitor for your system if it is about 800+ watts, you will notice the difference immediately

Amp stoped working


You need to run a larger power/ground cable. If you are reading low, you are not getting the kind of voltage that the amplifier requires to run, you may have been fine before adding the other products but if you wired them all to the same power wire (say an 8 gauge) you'd encounter problems. You should probably use a 2 gauge or at least a 4 gauge power kit.

The 1501 is very similar to the 81000 but there are important differences. The 1501 is a better amp.

If you turn the gain up and down, does the woofer move in and out in direct relation to the rotation of the gain?

What do you mean by "you only feel current going through subs"?

Clueless..!


You either are suffering from phase problems with the way you have your subs wired or you fried them and just don't realize it. I sell the TE1501D and these amps are not poorly made, they are however too powerful (1500+ @ 1ohm) for most subs on the market to handle continiously.
