Car audio amp and sub question?

check out the rms on that amplifier and the rms on your sub...technically sure you can hook it up too that amp but if you crank it up too high and your sub isnt rated for it you could blow it up. just be careful with your gain unless your sub is rated for whatever that amp puts out then you should be able to crank it no problem.(given your amp doesnt overheat). if the amp your using is rated at 800 max then its rms is probably alot lower then that... but really who knows companies these days put out all kinds of crazy numbers that dont mean jack. Just hook the thing up turn your gain up until it sounds nice and loud without distortion and monitor your amp for overheating and you should be fine.If your amp gets hot really fast you are underpowering the sub if it doesnt get hot and the sub looks like it about to jump out of the box you are overpowering it.. if it doesnt get hot really fast and the sub doesnt look like its about ready to self destruct(along with weird distortion) then you are fine.

Given that the 800watts you've given us is in wattsRMS, and not peak power, and that the sub-woofer is rated at 800wRMS or over, you should be fine. You'd also have to check that the amplifier is able to drive 4Ohms without damaging itself. The size of the sub-woofer, ie. 12", 10" etc doesn't matter in terms of power handling. It only matters for the sound you want out in the end.

yes that sounds about right. 800w, possibly 400+ RMS. For 1 12" 4 ohm sounds like it would fit perfectly.
