## Description

Use-Like New Alpine MRX-M100 Mono 1900 Watt Peak / 1000 Watt RMS Class D Digital Car Audio Amplifier with MOSFET Power Supply and Nickel-Plated Screw Terminals

Review: Beats Hard! - Great amp. Very efficient and good cost/watt and is very loud hooked up to my 2 4ohm 12" Infinity Perfects in a sealed box. I upgraded my factory alternator wiring and ran 4 gauge from battery to 1F cap and amp and 4 gauge grounds directly to chassis. I used 10 gauge speaker wires to each sub. This may be slightly overkill, but I think I am getting the full power of this amp. It beats hard. It runs cool, but will get hot if you run it loud for a 1/2 hour or longer. Also, it does cut in and out if run hard for a long time (like only during continuous rap type bass and it would cut in and out very quickly so it didn't totally shut off which is better than totally shutting off like my Rockford amps). Seems like very nice build quality for the price. More expensive Alpine/JL/etc. amps are better, but this is the best 1000Watt amp for the price.
Review: Never buy a used product. - Ive always relied on Alpine, they are by far the best sound company out there (in my opinion). I decided to be cheap and go buy the used one of this amp, new one costs around 300, and it stopped working on me after a week and a half. lol >.< Word of advice; dont buy used products.

## Questions & Answers

**Q: I have this paired with one type r 12, where should i have the gain set so that i get the most out of my sub without blowing it?**
A: I would set it no higher then half with the bass boost about third way up. I blew a 15" type r with the same amp wired art two ohms

**Q: so it puts out more power at 2 ohms more then it does at 1 ohm?... im confused**
A: Yeah, Alpine built this amp to be a 2 ohm amp. That's where this one puts out 1000

**Q: Can this amp handle a 10 inch 800 watt skar sub?**
A: Is the subwoofer 800 watts rms or is it's Peake power 800 watts? Either way if it's true is 800 watts rms then yes the amp can more than handle the sub. But the thing is...... alpine products are 100 percent spot on when it comes to there information about true power.... other lower grade brands fluctuate dramatically. My question to you would be can you sub actually handle  a alpine amp at a true 1000 watts Mrs.? I have 2 of these amps powering 2 12 inch 1000 watt type r 1000 watt rms alpine subs and they put out a ton of power.... I ended up also upgrading to a competition alternator.....

**Q: Would this amp be a good match for my (2) 10" Audiobahn aw1000x/4ohm/dual v.c./600watts rms (each)? Any response would be greatly appreciated.**
A: You can only wire those to 1ohm or 4ohm with both subs, so you'll only get ~600Watt instead of the 1000watt at 2ohm.  It should work fine, but just not as much watt/$ as if you had a 1ohm stable amp or 2ohm load.

### ⭐⭐⭐ Not a bad amp, delivers a lot of power
*by T***Y on October 10, 2014*

Not a bad amp, delivers a lot of power, however it doesn't seem to cover the range as much as I would like, seems to soften out and not do well with certain tones.
