Power connector block for MTX MXA8001

Anyone know where you can get these blocks?? MTX says "send it in" - they don't sell amp parts. It uses the same board as the Coustic model 1600DB.

Has mtx stop selling the mtx ta81001?

Hello t3h_b,

The MTX web site shows the amp as a current product. sells the amp and claims to have it in stock. However, MTX lists only 2 authorized online resellers: and

Crutchfield doesn't list the amp at all and SonicElectronix shows it as "discontinued". I'd recommend going to MTX's contact page and ask them directly. They'll usually respond within a day or two.

Hope this helps.

Amp shutoff while playin

It may be a mosfet in the power supply section that is blown. These parts are usually available from electronics part suppliers. Or it may be one of the amplifer transistors that is blown and it will also usually be available from parts suppliers. This fault is usually caused by battery voltage dropping to low so the amplifers output starts to clip and put D.C on the mosfets causing them to blow.

Amp is a mtx 801d not sure

no you will not blow it out by hooking up both voice coils. But First before you do, what oms are they. and is your amp one oms stable? There a lot of ways you can wire double voice coil. But if you can get me that info i can send you some digrams to help you out and tell you whats best.

MTX 1501 D

If the terminals were smoking, it's probably due to loose screws in the terminal block or wire that's too small.

Did the amp work properly after the terminal blocks smoked?

There are a lot of problems that can cause the amp to apply DC to the speaker terminals.

Before we go any farther, you should know that this amp stores enough energy to kill. When power is applied, the transistors must be clamped to the sink. After removing power, you MUST wait for ALL LEDs to go COMPLETELY out.

You need to CAREFULLY measure the DC voltage from leg 1 to leg 3 of all of the output transistors (the ones you changed). Post a list of the voltages and circuit board designation (FETxyz) for any that read more than 1v.

Do NOT let the probes short to other pins or to the heatsink when measuring the voltage.

Remember... High voltage and lots of stored energy. Be careful.

Amp works fine i think??? but Prsim efx not working at all

You need to contact MTX tech support before the warranty runs out. You'll probably have to get an RA number to send it back.
