Im getting my first system and its 2 12" kenwood subs 400 rms each with a 1600w amp what do you think?

-To keep from having to possibly spend more money than required, you only need an amp with an RMS rating that is 70-100% of the combined RMS rating of your subs. For 800 watts RMS, an amp rated at 560-800 watts RMS is plenty.Thats pretty awesome. Get ready to have to strap down stuff in your car. I know someone who sold some two 12" mtx's because it was literally breaking stuff on his car. it broke part of his body kit! haha

But yeah, thats pretty nice
I'd take it!
