Alpine MRX-M100

Fantastic little amp

I have a stock 90amp alternator and I have ZERO dimming, or much voltage drop for that matter.

This amp is super efficient and sounds great. I upgraded from a Hifonics HFi A/B amp bridged to 400W RMS, and wow what a difference. So much more detail and sound, especially at lower volumes now. It's like night and day. I would definitely recommend this, and I am even considering getting a V-Power for my fronts too.

dimming lights on this amp?

Make sue you are using at least 4 gauge wire for power and ground. I have this amp and it drives 2 mtx thunder squares at 2 ohms. ts 55's, and it performs fantastic, never gets warm etc>>> just trying to maybe help you out a bit and maybe you have done all of this. however, have never had and alpine issue of any kind. had alpine products for 25 years . i really hope this helps, if not you just might have a bad one, does happen to all electronics sometimes? take care.

Great amp

This is a great amp lots of power and since its digital it sounds great.
Pros:
-small
-runs very cool
-lots of power

Cons:
-Alpine doesn't send any stickers

its ok

had a m1000 few years ago hooked up to 2 10" kicker L5 it overheated fried and melted the fuse box. Only amp i have ever had a problem with on the other hand sounded awsome while it lasted!

A disappointment

I bought this amp a from Best Buy a few days ago. The one I got was birthed at 1110 w rms into 2 ohms. It dims my lights more than the powerbass asa 1500.1Dx that I used to have (which i ran at 1 ohm), and it makes much less power. It gets hot fast also. I have a 250 amp h/o alternator, so I do not know why I am getting so much dimming. Also it clips the signal really easy.

Lots of power for two type r 12s

Very reliable, lots of power, not too big, even looks nice.
