Yes, Alpine amps are good and they are underrated as their written specs. As I am saying, their amps are fairly small. Easily get hot. Trust me or not.! I just giving suggestions.! No one has been selling me any Alpine amps or any types of speakers yet.!
But, ( LOL ), to be honest, I am usingthe Alpine deck. The most lovely about Alpine, are their decks. Prices are reasonable and also in good sound quality. One problem thus, which is the same old problem of Alpine, it gets hot too easily. My Alpine deck gets hot once i hit to 25 volume and run it for an hour or so. Than the Cd seems get hot and the cd-reader seems not reading the cd-data properly. Starting to hear some zzaa zzaaaa sound.!
For normally listening, its perfection to me.!
