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.

Power remote and ground. Speaker wire

Use a volt meter to check the power going to the amp. without disconnecting the wires, put the leads on the + and - terminals. you should be getting at least 10V but hopefully closer to 14V.If not, check it is properly grounded and good connection at the battery. Next check the speakers. use an Ohm meter to check the Ohm load. disconnect from the amp and check they are not below 2 ohms (although 4 is better).
plaese rate if this was helpful!

If none of the lights are coming on for the amp then the amp is not getting power and/or ground. Check the connections. Check the fuses. Or the amp is no good.

Your basic crossover is going to have a power (+) and ground (-). Your power wire goes to the battery, and your ground goes to the frame. You will need to hook up your RCA or speaker wires to the input side. Then hook the other two RCA connections to your amp.

yes, the amp can be used fof full range speakers. to use it a s such, the amp's "crossover" switch must be set to "off" (could also be labeled as "full-range" or "defeat").

the amp is 2 channel. 4 channel is for surround sound or to have independent front and rear channels/volumes. this 2 channel amp will support 4 speakers, but you wont be able to balance from front to back- the front and back speakers will be at the same volume all the time if both are hooked up to the amp.

I can't be sure but it sounds like the battery just can't supply enough current while the car is starting, which is not unreasonable as the current load to start the car is quite high. I can only suggest fitting a capacitor as near to the unit's supply as possible or fitting a much uprated battery.(Batteries also lose the capacity to provide high current as they age, how old is the battery?)
I thought the fitting a capacitor was more or less standard in high power installations these days?

if your talkin external fuse use a 32v fuse

Using a multimeter, check the power going to the amplifier for around 12 volts, and check the remote wire for anywhere from 3 to 12 volts. If power is getting to the amplifier and the remote wire is signalling the amp to turn on, check the fuse/s on the amplifier. If the fuse is not blown, have the amplifier checked out by a stereo shop or send it to the manufacturer for warranty repairs.

Check your remote wire on both the deck and amp... If the remote wire is loose it will turn the amp on and off constantly... Also check to make sure that the fuses on the amp it self are properly seated.
