there was a guy that came in town selling orion and massive products. one of my friends went to him for 2 massive 10s and a massive amp and the install. each 10 had about 2 cubes with a slot port down the furthest side from the middle. im not sure of the amp wattage ... maybe 500 or so.
i dont know the exact model either b/c i was gonna look it up, but he didn kno what he bought *obviously had money to spend* it sounded clean but then again anythign sounds clean at low volume. i think he spent around 500 bucks or so for the install and all. def not worth 500 bucks. in a blazer it should be even louder also. i hlped my friend move 2 legacy subs and a legacy amp from his blazer wher eit would literally shake your hair, into his new truck *under the ext cab rear seat* and it was like ..... NO bass
anyways, i wasnt impressed, im never impressed with anme brands though so u might not want my advice
