The light on top on my MRP-M450 blinks and the amp doesn't work
I just hooked this up in my car...I had it in my truck previously with a dual voice voil sub at 2 ohm load, and though it's a different sub in the car it's still a DVC at 2 ohm load.
I literally just wired it, and turned the stereo on. It started working fine, and I was adjusting the LP filter, Bass EQ and Gain knobs, and there was a popping sound and the sub cut out. When this happened the power light started blinking too...it's lit but it just seems like an intermittent blink or cutout of light.
I didn't have the stereo turned up nearly as loud as I previously have in my truck, so I'm not really sure what I could have done wrong.
I took the back cover off of the amp and nothing seems burned...what else can I check?

Well if you took off the cover on the amp and nothing seems to be burn't, check the voice coils on the sub. It's possible the voice coils have separated and is causing the amp to short it self out due to ground error. If that doesn't help let me know and I'll tell you the next step.

if you are sure its the amp. the problem is internal. but if your not sure, try a different stereo or source of sound to the inputs of the amp. if there is still no sound than it is the amplifier and it could be a number of things.
The amplifier may be overloaded, check to see if it can handle 4 OHM loads and 2 OHM loads. if it turns off at high volume the amp may be overloaded. if so try a 8 OHM load. if it still turns off it may be an internal problem.
my friend your amp could be getting power that does not mean that it is working.the power only goes to certain point but because your regulator or other related component is defected your amp power supply will not work until the defect is corrected.take it to a tech and have your set repaired.good luck.
im having the same problem with my amp, I took it to best buy and they said the amp was recieving power and recieving signals from the deck and i had everything hooked up right but that in the circuit board all the connections were blown, meaning i have a blown amp, i hope this isnt your problem but it definetly sounds like it. GOODLUCK
