I have the Alpine 9853 and would recommend it. Tuning it wasn't easy, but I am now very pleased with the sound. I should rephrase that tuning it wasn't easy due to my Audiocontrol EQ, and DEI crossover, trying to get them all in good harmony was difficult, if you just have an amp or two it shouldn't be that hard to get the internal EQ and Crossover set. This is my 2nd Alpine and I haven't had any problems.
