MTX 4501 Mono Amp - no output

Hooked up new MTX 4501 Amp tonight and no out put under normal hook up.

Did get the sub to work when holding down the cross over button, but goes silent when releasing the button.

What could it be ?

Thanks

It sounds like you have a defective switch or a broken solder connection. If the amp is new, return it for repair/replacement. Don't break the warranty seal if it has a warranty.

Your amp went in to power protect. You must adjust the settings on amp. This is usually very time consuming to get it right. Good Luck

MTX Thunder 81001 wont push subs


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.

Help connecting the sub


Your sub or amp is probably blown. Do you get any power to the amp? try hooking up another speaker and seeing if you get any signal at all.

Mtx 895 trouble


check your fuse up front first. some amps will turn the light on with only the remote wire (the 12 volt signal from the head unit). That may be your issue. If not you need to check your signal input. try hooking the rca's to a diffrent source, i.e. other radio your tv anything with Rca out put. If still you get nothing then pull your subs out and take a regular 9 volt battery and touch the leads to the positive and negative of the sub. Just for a moment though if the subs move when they come in contact with the charge from the battery then my last suggestion would be to take it to a store where you can have an authorized tech check out the equiptment. Good luck
