Sounds like issue with speakers or wiring. Hook one up at a time and see if lights come back on.

SOURCE: 2 red lights after x clamp replacement

It means basically that the xbox is starting tio overheat fast. what sometimes happens is those x-clamps have to be tightened in a sequence and tight as possible but not too tight to crack the board or cut the small PCB traces. Open up the console again and just have a look underneeh the motherboard make sure there are no torn green pcb traces ( put simply green lines that connect to a silver blob of solder ) and make sure the screws are tight enough.

Hello tonytone54, The ground should go directly to the vehicle frame, never through a cap, fuse, or anything else. Also, if you are connecting positive through a cap, make sure that you charge the cap before connecting it. Hope this helps.

SOURCE: mtx thunder 304 4ch red amp light comes on but no audio

if the lights on and there is no sound it's either a cd player issue or your rca issue or the inputs for rca's on the amp are no good. or you have your subs wired at a wrong load to your amp and it is in a constant protection to avoid burning up.

I bought a mtx terminator amp model no TNA251 600 watt and two subs installed. It works good for few days but now its not cranking up proper bass and sound. It always has three solid red lights everytime....


does it do this all the time when you turn it on? any sound at all?
provide more information, but my guess its that the amp is blown. replace it or sell it for parts.

I have the same sub combo. The problem is the amp is underpowered for the 2 MTX 12s, get a bigger amp and you should be fine.

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


The TS55 is a DVC subwoofer that can be wired for either 4 ohms (voice coils in series) or 1 ohm (voice coils in parallel). The appropriate wiring depends on the amp.

If the amp is stable at 1 ohm, wire both positives and both negatives to the matching amp output terminal (parallel) as shown in Wiring Option #1.

If the amp isn't stable at 1 ohm, connect a jumper between the positive on one voice coil and the negative on the other voice coil. Then connect the remaining positive and negative to the matching amp output terminal (series) as shown in Wiring Option #2.

I just replaced my old terminator 12" subs with two new 12" jl audio w3 4ohm subs and the mtx terminator amp keeps shutting off and flashing red. I kept everthing the same from my original mtx...


You may have touching speaker leads going into the amp. Make sure the tinsel is not touching across the speaker inputs on the amp. Also check your ground. It should be solidly connected to the vehicle chassis in a paint-free location. Finally, make sure there are no exposed speaker wires touching the vehicle chassis.
