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.

I have a mtx thunder 421d. I've had it about 5 years,about a week ago it started going out from time to time. I checked my hot wire and fuses,they are ok.Now the amp stop working, and dont light up. Will...

If you have proof of purchase(invoice or receipt) showing the purchase date and you are still within the warranty period then yes it would be repaired by MTX under the warranty guidlines, and by the way MTX is great at customer service and they are great to work with(very fair)!!!!
Keep in mind that the seal on the bottom of the amp cannot be broken or that will void warranty coverage.
Give them a call, you will be glad you did!

I have a TN250/1 MTX class D, mono-block amp, protection light comes on and thats it. Whats the problem?

Two things, a problem with the speakers, or the amp is toast. If there is a short is the speaker, wire touching, bad voice coil, the amp will go into protect. I have also seen many, many MTX amps that go bad, and just stay in protect. the easiest way to check, is to unhook the speaker wire from the amp, then power it up, if it still goes into protect without a speaker hooked to it, you have a bad amp. Hope this helps.

Need proper wiring details.

This is a dual 4 ohm sub. By wiring the terminals in series (one set of + to - from one side to the other) you will have an 8 ohm sub (most folks probably don't want this). By wiring in parallel (+ to + and - to - and connect the - wire to the - terminal on your amp and the + wire to the + terminal on your amp you'll have a 2 ohm sub.

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.

Amp only plays during low engine rpm

yes, the overvoltage...compounded by maybe an alternator that is also not operating within limits (Does your headlights or horn get brighter / louder?). look inside the amp for any adjustable device for OVER VOLTAGE THRESHOLD or similar and turn it slightly clockwise

Amp Will Not Stop Overheating

You say you have 2 p312d2 subs. Ok so the d2 stands for dual 2homs (2 X 2homs voice coils per sub) , conecting in parallel the 2 voice coils of only one sub will create 1hom load to the amp, and if your amp is 2homs stable per chanel that means you are lowering too much your homs causing the overhwating to it.
