no.... you can see it in the picture!! and for support of the sheet underneath there are side beams!! its pretty solid !!! GUYS EMM I WAS THINKIN OF GETTIN PIONEER D1200SPL! should i go for it?? its for 45 thousand brand new excluding shiping! its 1200 rms at 1 ohm! any other option with in this range i guess this amp is going to give pretty clean sound and is wayyyyy above the required 750 rms for the sub so i think its going to beat well!! for now i will be using the sony that gives 500 rms at 4 ohms !! i guess that wont be pretty bad too!!
