A bit more info would be needed to give you an actual recommendation. The model of the drivers you're using would help. Also what kind of enclosure do you plan on using...it will determine what kind of features your amp may need...like if you're going to go with a ported enclosure then you may want an amp with a subsonic filter etc. Do you have certain budgetary or electrical restrictions? Are your goals more SQ or are you lookin to shake the block?
Yeah man, you need to advised you want to pound the pavement or more an SQ dude! Also please provide us the model number of your subwoofers so we know its single or dual voice coils. Also your ride so we know its not space restricted in size. Cheers mate!
Tiny so it will fit under a seat no problem and they do rated power. Little overkill for two 300 watt rms subwoofers but headroom is always nice to have.
