well whether or not you want to be heard or not, your probly going to be in a bandpass box. hehe. please not that bandpass boxes get loud, the sound quality on most is below par. but anyway, on to the amp. we need to know how many voice coils each sub has, how many ohms each sub is, and how many watts(make sure its a rms rating, not max) each sub can handle. i'm probly gonna say a jbl mono amp, but i dont know which one, until you give us more specs. you can get either 4 channel 2 channel, or mono channel for your subs. however i would go with mono channel, its just plain eaiser. both subs are going in the same box right? well wire the subs together, the wire the single channel of the amp to the terminals on the box. keep it simple.
