How do I wire my 12inch mtx ts 55 subwoofer two outlets red with red and black with black or red and black and red and black

Tuning is a function of math related to the enclosure..You need HXWXD and material thickness, Speaker type and SPL and port size if you are going to have it ported.

This site well be helpful for you to configure the connections

Check your ground wire it could have dislodged itself and needs to be refacened

May have a blown channel in your amp.

it doesnt matter which way you connect them as they are only a coil when all is said and done at the end of the day ,their will be no loss of performance with the wires either way around ,l would imagine the grey and white is the earth but it doesnt matter

Red is positive +
Black is negative -

The little plus and minus marks are your guides, they should be on the adapters to tell you which is which.

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.

Hello moore_broder,

Your MTX 7801 is stable at 1 ohm, but you cannot wire a pair of DVC 2 ohm subs to that impedance. They can only be wired to 1/2 ohm which is too low or to 2 ohms.

Series the voice coils and parallel the subs. On each sub, jumper Black to Red/White Dot, then run both red's (positive) and both black/white dot's (negative) to your amp terminals.

The diagram is here.

Hope this helps.
