Generally when you have all your connections sorted disconnect the power and reconnect once all other wiring is complete,if the red light comes back on its more than likely there is other problems.

I have a problem .. I have a mrv t757 amp and it isnt bumping like I used too .. If i keep the volume low all 3 lights are green but once I turn it up it blinks red n yellow n green back andn for in the...

check all your connections to make sure you don't have a short, but most likely it's your amp. If it was the battery it would turn on and off, including radio, then your car wouldn't start(dead battery), but if it does this and your car turns on no problem then it sounds like the amp gave out.

The light power is red and it smell like melt

on an amplifier that usually means that its burnt out, or that you've melted one of the wires. check the ground wires and whatever you have the amp sitting on. if everything looks alrite then its most likely the inside of the amp is fried.

Hi Big Nick,


Sounds like you have got almost all the good out of those Subs. You can find the screws you need at almost any hardware store or Auto parts store. The light is becase you are dloading the amp with low OHMS.  You may need use one channel and Run the wiring like written blow to get the power problem to disappear.
