Alpine Mrx-m100 - Monoblock 1000 Watt RMS Subwoofer Amplifier

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.

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.

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.

This Amp was actually very good,it paired well with my Alpine Subs,but it Completely died on me all of a Sudden.

great just not enough power

I have this hooked up to 2 12" JL W3V3's and it bumps hard and is very crisp. The power of this amp perfectly matches the speakers. I have the gain and everything set correctly so that at max volume you are 1 tick away from clipping. And at that volume it makes good bass. Obviously it sounds better with my JLs than it does with my kickers. But definately the best 1000w amp for the money ive encountered.Ive had this thing bumping for 21 months. Still going strong. Usually for me 2-3 years is about all i expect out of an amp so its approaching that mark soon. Hopefully it will continue for a bit longer so i can upgrade when it goes out. But definitely my fav amp for the price.

The amp did its job in the beginning. I never pushed it to it's limit and it only lasted a little over a year.

I had it professionally installed. As soon as I turned it on , it never worked at all. I would recommend to go with another Amplifier because mine did not work whatsoever. Very upset considering I paid around $250 for a broken amplifier
