    The amp was on sale so I bought it in november!  OMG!  Pioneer 10" in single enclosed box freaking slams my 79 chevy blazer like mad!  I Had to turn the gains down on the amp was afraid to blow the subwoofer up!  Going to add another subwoofer onto the amp here very soon,  has dual sub hookups and auto drops to 2 ohms for you!  Crossover build in and has rca outputs as well for adding more amplifiers to the system!  Hooked up to an alpine cdx stereo and pioneer 2 way 6 1/2!  I would recommend this amp to anyone,  just make sure that you have a good high powered subwoofer cause its pure raw power!
