I have 6 of these in my range rover sport in a sealed enclosure on a kicker warhorse amp @ 2ohms with 3 sets of GTI components. With the JBL sound processor. Gets very loud and crystal clear. You will love it!

I blew this sub up 2 times it sounds good when it works tell it blows, wound get another one, i would go alpine type X hits hard and gives clean sound...
have to love sonice tho #1 prices and tech

I have always wanted this sub from when it first came out years ago, if you are after a real SQ sub , this is the one. I have it wired to 3ohm and feeding it 1000rms all day, even tho its rated at 600rms, it is more than capable. If you are going to buy this sub , please do it justice and sound deaden the inside of the box and use marine ply 18-25mm, sealed. you will not regret buying the MKii range of subs, it goes hard and plays very accurately.
oh i and play D & B , Tech death metal every day for at least 3 hours, JBL = WIN!

I have (1) one of these. Yes, just one of them in a 2.75 cubic ft. PNR ported enclosure, running it is a Phoenix Gold MS 2125. Hits deep like 15's, with the Audio Control Epicenter. Its all about the enclosure, a damn good sub like this, and an American made old school amp. So just build smart and lets take it back to basics for car audio in the year 2010.
