MTX Thunder 81001 wont push subs

I have an MTX Thunder 81001 with 4 gauge power wire. Everything is wired right and the amp comes on but it is not pushing the subs. Could my power wire be too small? The subs are doing NOTHING.

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.

Power light on my power acoutics amp and also my mtx 81001 thunder mono block amp turns on but no sound comes out to the subs?? how do i fix it? or they are no good


you maybe plugged the RCA's into the wrong inputs. or the amplifier is damaged.

turn up the gain and check the output settings of your deck and turn on the sub out channel.

Need to know how to wire my system ...I have the infinity reference series 611a I was told it was a mono block but it has two channels on the exterrior...also I have two 12 inch MTX thunder dual voice coil...


it all depends on what kind of box the mtx subs are in as far as wiring the subs. The best way would be take the speaker wire from both sub boxes and run the positive into the right positive then the negative into the left negative. and run 8 gauge wiring kit to the amp because 10 might be to small and 4 is to big 8 gauge is perfect for this amp.

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.

Mtx thunder 6152 is getting way to hot and shuts its self off when it get really hot


okay, first thing i would do is turn down your gain. Sounds like you are over working the amp thats wire your amp gets hot and shut off, it's going into protection mode. Is your amp enough for your subs. Some times not getting enough power to your amp might do this too. But if your subs wattage is way over your amp watts, you need to upgrade your amp. Also check your subs and see how the are wired up with the ohms, And see if your amp can take a 1 ohm stable load or how ever it's wired up at. hope this was helpfull.

What is Positive and what is Negative


Hi Mason.
Are the positions colour coded in any way?
Red = Positive
Black = Negative
I've looked at some photo's from the website and at a guess I would say that yours are the push on crimp types, so no colour markings.
Have a look at the pdf wiring diagram they supply here as it may shed some light on things:
MTX Thunder US-XT12-44
I've looked over loads of forums but none seem to mention the wiring of these subs.
Understandably you want to get this right as they are a very nice set of subs when they're up and running.
If all else fails try looking at the MTX contact list and ringing one of their supported dealers for more info.
Regards
Mike

Subwoofers won't work and they are brand new


Hello,

I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.

My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.

First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.

Confused


Hi jimmyjames,

 

How do you have the wires hooked from the sony reciever to the inputs on the mtx? 

 Sounds like your Remote wire is way too big. it should be 14 guage.  It only sends a low voltage low amp signal.

 

Another thing that could be messing up the sounds is the routing of the wires.  you should have the power supply wires separate from the Audiop signal wiring.  Power should run down the Driver side and Audio down the passenger side.

 

When you answer I may be able to tell you more.
