I don't usually write reviews for a 10 year old product but for the Alpine MRP F-240 I will make an exception! I installed this in my truck sometime around 2004-05 if I remember correctly, it is mounted to the rear cab wall behind the seat back, as is my MRV M-500, it is a tank! Not once in the entire time I have owned it has it ever given me one single issue, no faults, no protect mode, nothing to complain about! It is a shame they don't make it or any of this line anymore, of course time marches on and perfectly good products get replaced, but I am always looking out for one on EBay and CL just incase. If you should happen to need a tough reliable amp to run your main speakers and you come across one of these don't pass it up just because its an old model. It was originally running 2 sets of Kenwood 5"x7" speakers in my doors, now it is running 2 sets of Infinity Kappa 5"x7" speakers with a set of crossovers and added Infinity tweeters in my front doors. Peaked and tuned each time, running 12 Ga. wiring having ditched the factory F150 wiring a long time ago, when I added the subwoofers and the M-500 I really thought about updating it, but thankfully I talked myself out of it, probably because it required more work! My truck does truck stuff, it hauls, it tows, it goes off road and loves the snow, this amp has taken every bit of abuse I could throw at it and just kept on cranking out the tunes!
Pros: Solid, tough, capable, powerful, compact footprint even for its day, basically indestructible!
Cons: They stopped making it!
